The damn Actuonix linear actuators with potentiometer feedback don't even come with limit switches. I hit the limit for a just a second and the entire housing started warping. Damnedest thing I have ever seen. Glad you guys designed it right.
Thanks for the video. You both explained all the questions I had with perfect detail; opening the unit itself and displaying the inner working of the actuator was a bonus.!
Looking at one of these linear servos to convert a riding mower into a RC mower. Gonna need one for steering, and a light duty one for actuating the hydrostatic transmission control lever. It's gonna be sweet!
Thank you so much for the video..its very informative.. I had coded a program to set a timer to count the forward extension and reverse retraction of the actuator using 16f877a and to display the time in LCD.
Is there an amount of what they can push an pull ? Is there a certain amount of pressure you can do this with ?. Also what sizes do the come ? Also is there a a breakdown of what poundage you can use . Basically if I was standing on it will it move me up or will it break due to ,to being to lite of a motor .
It sounds like you're after a linear servo of some sort, likely combined with a microcontroller to send it position commands such as an Ardunio (www.servocity.com/pololu-a-star-32u4-prime-sv/) To interpret the signals from a solar tracking sensor or something of the like.
So I may or may not be planning on using this to gimbal a rocket nozzle… Do you know anything similar that can open and close without having to manually change it? I’m not a professional at electronics lol I think the simplest way would be an automated modification of the system shown at 3:20
Hello, If I'm understanding correctly, you want a system to continuously run in and out? If so: I think the easiest option would be the combination of a motor controller, an Arduino, and a Linear Actuator. The linear actuator has a pot that communicates the position of the actuator. The Arduino can read that pot, and control a motor controller. Some simple code could tell the motor controller to run the actuator in one direction, or the other depending on the current position of the actuator.
I bought an actuator for my boat trim motor and it lasted about 3 weeks before it died. I made sure it was water proof and then I also sprayed it with water proofing. So that is one thing you forget to mention. It had much more dynamic and static load rating than I needed and was the correct voltage. It was slow but I would rather slow than not enough lift. Anyway, I would be interested to know what went wrong. The company had a 30 day return but by the time I was able to install I really only got about 3 weeks out of it and maybe had to lift the motor 8 times during that period. Can you comment on what may have/could have gone wrong ?
You guys are great together, Cracked me when you pulled out the linear servo how Jason was looking at you thinking "why is this dude trying to one up me man"
Awesome vid...does the amp of battery effect the actuator? Asking because I plan to install 2 linear actuators in my truck and debating if I should tap off the truck battery or off separate battery. Thanks
Thanks, Benjamin. If you are running linear actuators, you can tie them into your vehicle battery without a problem. The motor in an actuator won't be bothered by the fluctuation in voltage due to the alternator. More care would need to be taken if a micro-controller were in the equation. Feel free to email us should you have any other questions tech@servocity.com.
Very good demo.I like the contrast between you two, I actually learned a lot from two perspectives, that was very thorough and satisfying considering my obsession with finding out everything tech,especially electric motors I will subscribe and like. I love the way you get down to business, no extra B.S. I’m a K.I.S.S. fan myself, keep it simple is usually my aspect on things, I also enjoyed the disassembly, appreciate the convinces you 2 have provided and fantastic presentation!
A couple questions! What is the noise rating on the servo? Also, if I were to open the servo and move the limit switch on the fully-extended side (desolder, drill, solder), would the servo have a correctly-functioning shortened range? I'm looking to do ~85 lbs with a ~1.5" throw and it would be excellent to have the safety in hardware, not software.
Hello! Great video. Is it possible to create an automatic reciprocating (preferably adjustable) movement with a linear actuator (without having to turn a switch back and forth) and if so what equipment would one need? Thank you so much 😊
Great video, area there any problems that you are aware of regarding installing them in a hot humid greenhouse for ridge and side vent opening? Thank you.
Hi Charlie, our linear actuators and linear servos have IP ratings which will give you the extent of the water resistance. Feel free to contact our Tech Team should you have any other questions tech@servocity.com.
That was an awesome demo guys..I have a question..I am trying to build a scale model of an excavator using the hydraulic principle with syringes.these motors act as Pistons so I should be able to use them instead right,I want to know what torque do these motors have cause I want my excavator to dig and lift just like the real thing.are they expensive to buy and could you pls do a demo on how to convert it to remote control..tnx guys
You can certainly use linear actuators or linear servos in place of hydraulics if the speed, thrust, stroke length and overall size fit your model. Since we’re quantifying a linear force they are rated in pounds rather than a torque measurement. The amount of weight it can lift will depend on the placement of the actuator in your assembly. Prices vary based on what selection you make; we have HD linear servos which are the most plug-and-play solution for r/c. We offer HD linear actuators that are less expensive but more intensive to hook up to R/C (require a motor controller that can convert the PWM signal to a voltage that would get sent on to the motor). and SD linear actuators which are the same as the smaller ‘HD’ linear actuators but beefier for more industrial applications. The video covers how to connect a linear servo or linear actuator to a servo controller. An R/C transmitter and receiver is just a wireless servo controller so it’ll connect the same way. Please let us know if you have any additional questions tech@servocity.com
Super!!!tnx for the prompt reply!! Another question..how does the boom of a crane extend..do they all have multistage cylinders or are they also equipped with linear actuators within each boom extension? And i.would really appreciate it if u could do a demo on how the excavotor rotates 360degs and still powers its tracks without its wirings and hydraulics getting twisted in the slew ring.i have looked online but not really satusfued with info or the lack of detail given. Cheers bros!!
Here’s a link to a brief explanation of how a crane boom extends: answers.yahoo.com/question/index?qid=20081125153736AAiN8mW. I would have to do more research on an excavator before commenting on the rotating base; sorry I couldn’t be more assistance in that department. Let us know if you have any other questions tech@servocity.com. Thank you
You will need to consider the IP rating of an actuator in such an application. Most of our actuators are IP54. While it depends how you use your tractor, I would suggest looking for IP67 or higher. Feel free to reach out should you have any other questions tech@servocity.com.
Very useful video.because of the situation I will put it,sometimes it will work manual,so the power sometimes will be from the bracket to servo motor.Can it move?Will it may do a problem to the servo motor?
That would work with Linear Servos, you would need a servo controller sending the same signal to each of the 4 servos. That would keep them synced up well. Depending on the tolerance for misalignment in the mechanism, a standard linear actuator on each corner with one switch controlling them all may work just fine for you.
Great review. I have a question. If you stop it in the middle before it hit the limit switch and keep for a few hours does it use any electricity and drain the battery?
The current draw will be considerably less given the motor is going to be at idle but it will continue to draw from your battery until it's turned off of the battery is discharged. Let us know if you have any other questions tech@servocity.com.
Great video. My question is, can I remove the cover of my "Windy City" actuator and reposition either, or both of the limit switches to stop the extension, or retraction, at a particular position? Thank you.
Hey guys just stumbled upon your channel after trying to find a solution to a problem im having. I have little knowledge of anything to do with servos and could really use a hand figuring out what i need to do what i need to do. Im trying to make an exoskeletal arm brace/ elbow joint for my mum who suffered from arthritis and had many failed attempts at replacing the joint. She now has no elbow or bone 8 inches either side of where the elbow should be. Ive figured out the rigging now im stuck on how to wire up an actuator to extend and hold in place with one button and retract and hold in place when released with another. This is a long shot and im sure youre very busy but any push in the right direction would be amazing! Thanks for your time. Karl :)
If you remove power from an actuator the motor driving it has no voltage going to it. The motor will stop and therefore the actuator will stay in the position it was in when power was removed.
Actuators are very commonly used on gate openers. You'll just need to find one that is rated for the environment. The IP rating will tell you how well it's sealed up. Please let us know if you have any further questions.

If it's an actuator from ServoCity we have documentation online that would tell you everything you need to know. If it's from somewhere else, you could measure the resistance between the wires to locate the potentiometer wires, or, open it up and trace the wires. Please let us know if you have any further questions.
@@ServoCity it is not one of yours unfortunately it is a duratron mc42-1015h. It says 115v but I thought all linear actuator were dc. Came from a old hospital bed
If the actuator you choose pulls less than 1 amp under load then it may work. Some trickle chargers may have circuitry that keeps them from supplying voltage til they receive a certain amount of voltage from the battery they are connected to. To check your trickle charger, plug it into the wall, connect it to a multi-meter and see if it's supplying a voltage. Please feel free to reach out to our technical team should you have any further questions at Tech@ServoCity.com.
@@ServoCity Interestingly, a multi-meter does show voltage on my trickle charges But the linear actuator still won't work with any of them - must be some sort of circuitry in the charger to prevent this type of use - so I am scouring my supply of old AC-DC chargers from old phones and rechargeable tools to see if I have anything in the 12V 1 amp range
Hi David, there are various ways you could go about it. For example you could use a limit switch ( www.servocity.com/electronics/components/switches/limit-switches ) that is physically engaged to turn on the light. Or you if you are using something like an Arduino or Raspberry Pi with a servo hat you could use a linear servo ( www.servocity.com/servos/linear-servos ) and a PWM switch ( www.servocity.com/electronics/components/switches/pwm-switches ) and send two PWM signals, one to control the linear servo and one to turn on the light via the PWM switch. You could also use a PWM switch with a Y-harness and linear servo to run them both off of the same PWM signal (like from an RC receiver or Arduino, Raspbery Pi etc) but the light would turn on the entire time the servo is extending and not just at full extension. Let us know if you have any other questions tech@servocity.com.
Hi Parish, yes, that's one way to make a linear servo. Keep in mind that normal threaded rod is not meant for creating linear motion but for fastening. The threads of a lead screw are cut much smoother and more consistent to create linear motion while minimizing friction. Please let us know if you have any other questions tech@servocity.com. Thank you
Thanks for a great instructional video. I am going to use actuators to control my boats speed and shift her transmission. Do you know of any better suited for the marine environment?

i, I have an INCA TV lift with a tubular motor. We lost the remote, and lift got stuck in up position. Any advice how to bring it down? Any ideas or how to reverse the motor movement? Highly appreciated. Thanks for sharing awesome ideas.
Hello! That sounds much outside the realm of our technical support. If you'd like you can send our team an email and see if they can help you out. But no guarantees they will be able to assist troubleshooting other company's products. tech@servocity.com
Hi Jonathan, there are a lot of variables that come into play. In general, the weight an actuator can hold is greater than the amount that it can move. The amount that it can move is heavily dependent on the ratio you choose. Feel free to contact our Tech Team should you have any additional questions tech@servocity.com.
Here's a video on how to adjust limits on the Super Duty linear actuators. ua-cam.com/video/3jzyQ5gQUFE/v-deo.html Heavy Duty linear actuators do not have adjustable limits. Please let us know should you have any other questions tech@servocity.com.
First it's not up and down. It's in / out or extend / retract. Next the screw rotates, it doesn't move in or out. The lead screw nut is what travels along the lead screw and Push Rod / Extension Tube is attached to that nut. The gears that drive the lead screw are a combination of a worm drive/screw that drives the rest of the spur gears. OOPs My apologies. The one he is showing here does not use a worm gear. It is just a set of spur gears.
I am looking for some ideas as to how to build an old school arcade driving cabinet like Out Run where with the turn of the wheel, the base would move. I am thinking about putting an actuator or servo, I think 4 will do the job. But what I don't know is where to start or look for. Would something like these work at high speed sensitivity and would they handle the weight? I originally was looking at hydraulics, but outside of weight, they would seem slow. Suggestions?
Thank you for reaching out to us. If you could please send additional specifications to our technical department they would be happy to help with some recommendations at tech@servocity.com
The output force can be varied by changing the voltage or limiting the current supplied to the motor. If you want to have even more control there are force sensors available that could be used in conjunction with a motor controller as a closed loop system. Please let us know if you have any other questions tech@servocity.com
Is there a servo or actuator that is big enough to reach 8-10 feet? Or something that can reach close to that height? Working on a project for wireless surveys and need something like this to add to a pi
There are some very large linear actuators on the market, but I doubt you'll want to tote something of that scale around given the weight that is likely to be associated. If you take on building something for your application you might get some inspiration from an extension ladder; pull the rope and it extends out. You could use a motor to reel in the rope or cable that you use to drive your assembly. Feel free to email our Tech Team should you have any other questions tech@servocity.com.
Hi Sayan, the HD actuators are rated for 500lbs static load so far greater than the amount of thrust they can exert. I'm not sure what o/p means - if you can restate your question i'd be glad to help.
We have several different sizes of linear actuators and linear servos so they use different motors. They're all brushed DC motors at this point. Feel free to reach out to our Tech Team should you have any other questions tech@servocity.com.
I am ready to buy the linear servo for an autonomous boat installation using the PIXHAWK Flight/ navagation controller A- How do I go about connecting the pixhawk to the linear servo?
I want to use these motors for my robotic arm project.But my doubt is whether these motors are able to hold the weight of robotic arm when not powered or are at halt at a certain point .
Hi Saksham, the HD series actuators are extremely difficult to backdrive. It depends on your setup, but I would highly doubt that it will cause the actuators to move when powered down. Let us know should you have any other questions tech@servocity.com.
I've notice some linear actuator move super fast and smooth. They are almost silent. Are these powered by electric motors and a threaded shaft. The way they operation almost seems like they are powered magnetically. What are these linear actuators called?
It's hard to say for sure without knowing the actuator models you are looking into, they could be magnetic. However, there are also pneumatic cylinders that can be very fast, or hydraulics. If you still have questions please feel free to email tech@servocity.com and provide a link if possible for our team to look into further.
do you have a video on how to make an app for an iphone or any phone to be able to control an actuator? like having the actuator connected through wifi to be able to control it from your phone from say another state? thanks in advance!
I was looking at repurposing some adjustable bed linear actuator but the wire has a multi-conductor plug with 4 pins. Why? Can I convert this to be 2 wires like the actuator in your video. I can't wrap my head around why there's more than two conductors in the plug. The linear actuator doesn't do anything but go in and out to lift bed up and down. So why so many pins in certain bed actuator? I've seen some with 4 or 5 even 6 pin plugs on some. Can you explain why a simple motor would need so many condutors in the plug?
Hello! We are not sure why your unit has 4 wires unfortunately, it is possible it is not running a standard brushed-dc motor. Something like a brushless DC or Stepper motor would require more than 2 wires to operate most likely. It's also possible that the additional wires are some kind of feedback device. Our actuators for example have 2 power wires, and a 3 wire analog position output set. So 5 wires in total.
@@ServoCity I thought that could be the case. I think I will get the info off the actuator and see if that will help me find out anything more. Also I'll probably have to carefully cut back the wire cover and see how many wires are on the actual wire part after the plug. I was hoping to avoid having to do that but I guess I'll have to and test wires with my multimeter. Do you HAVE to hook up the extra wires for feedback? The bed controller I'm trying to use is better in every way than my current controller but the difference is the plug on the actuator motors. The new control box has just two wire sockets for motors but far more programming options than the much older box that has 4 pin plug. I don't see why there would be feedback wires. The original controller didn't even have massage or any other features save for "all flat" and two memory locations, so I don't think the extra pins are being used for feedback on such a basic model and old of bed. But I could be wrong. And if feedback wires are there, do I have to use them if the new controller doesn't use them? These are the questions that keep me up at night lol. I'm hoping that it's just two wires after the plug but like I said I will have to do some testing it looks like. And if I don't have to use the extra wires, then I won't. Do you know anything about not using the feedback wires? And just the motor power wires?
UPDATE... Additional info. The model from the label says fd24-a4-320.400-c12-p0 I looked up the specs hoping to find info on a pinout but nothing. I did find out what those codes mean and the very last "p0" denotes the basic version with no "Hall Sensors" which I assume means feedback sensors. Because they can have one or two and the code would change to "HS1" or "HS2" accordingly.... Which again "p0" means no sensors So it's looking better and better that the extra pins are not being used for feedback sensors.
Some cool information! I would agree that it doesn't sound like the extra feedback wires are being used. Please feel free to reach out to us via email or phone with any more info, but from what it sounds like they are extra and most likely there are just 2 wires that are being fed 12v actuator power. Most actuators are fully capable of running without their feedback device being read, it just allows more complex control of the unit.
@@ServoCity thank you for helping me to believe that my initial assumptions could be correct. One new thing I learned. I was facing a similar situation with the plugs on the massage motors. Again the sockets on new controller were two pin but the massage motors I picked up were 5 pin. I took the massage motor casing apart, reasoning to myself that these are nothing more than simple dc motors. Why on earth would you need 5 pins? Turns out you don't. The wire inside the casing and soldered to the motor was only 2 wire. So far my quest to put together my own upgraded adjustable bed is going wonderfully. Hope the linear actuator problem goes just as easy when I test those next. Thank you again for your help!
Hi guys! I have been enjoying the channel! Thanks for all the useful info! I have a question about linear actuators and remote setups that - I don't know if you could answer for me? But I thought you might at least be able to point me in the right direction... I have a project I'm working on that requires 2 sets of actuators. I would like them to operate independently and I am trying to use 1 power supply and 1 2-4 channel remote. Let me know if you can help. Take care!
Thanks, Ryan and glad you've found our videos helpful! Our Tech Team has sent an email your way to answer your questions. Let us know if there is anything else we can assist with.
If your still around I would like to ask a question. I have an actuator that has stopped working (extending and retracting) and need to raise (retract) the shaft to its shortest length. What would be the simplest way to do this manually, if possible?
It depends on the design of your actuator, but if you can access the lead screw driving the piston, just rotate the lead screw manually (assuming it will still turn) to manually extend/retract. Feel free to contact us should you have any other questions tech@servocity.com.
Is there any way we can get benefits of servo actuator in linear actuators with some simple additions or changes.Secondly what's cost difference in general? What's the max speed force and stopping accuracy of each of them?
You can create a linear servo on your own using a linear actuator and a motor controller that has positioning feedback. Cost is dependent on what components you select for your project. Speed is dependent on the ratio you use and accuracy is going to come down to the stroke length of the actuator (as that will somewhat determine the resolution from the potentiometer) and the circuit board you choose to drive it. Email us at tech@servocity.com if you have any other questions and we'll assist you.
@@ServoCity thank you for elaborate reply.Readon being as a designer one tends to over design by using servos thereby increasing overall cost Thank you providing your contact email.

good info and good video. Now if I wanted the servo or actuator to just keep going in and out on its own but be able to control the speed how would that be done. To add another option if I wanted the auto function (the in and out on it own) with speed control then switch it to be able to control position. how is that magic done? any info you have or if you can point me in a direction. please.
Hi Darrell, sometimes a rotating assembly (think crank, rods, pistons in a car engine) is a preferred setup for linear motion that runs continually. This will keep from having to ask the motor to change directions over and over so your efficiency can potentially be better. If you want to use the actuator I'm sure there are many ways to do it electronically - one of those ways would be to slightly rewire the limits and include a latching relay that would allow it to change direction when either limit is contacted. If it's a linear servo just have a controller with a program to tell the servo to go in and out at whatever rate you want. Note you're using the position control to control the speed in this setup but it works just as you've asked. For the position control setup you've requested while using an actuator, a motor controller with a feedback loop could be used and a program could be written to precisely control the position of the actuator. Or if it's a linear servo just have a program sending the PWM signal to the linear servo (much like setup 1 using a linear servo) but have a manual mode where you can adjust that PWM signal with some form of input (potentiometer for example). Let us know if you have any other questions tech@servocity.com.

hello, excellent video !!! Do you know if the linear servos or the linear actuators would have the necessary force to be able to step on the clutch of a mechanical car? If so, please recommend one. I am disabled, I appreciate your response.
Glad you found our video helpful, Braulio. Yes, a linear actuator or linear servo is capable of actuating the clutch on a vehicle. There are a lot of variables involved such as the position of the actuator in relation to the fulcrum, the type of clutch (mechanical, hydraulic, etc.), the pressure of the clutch, rated force of the actuator, etc. Please contact us should you have any additional questions tech@servocity.com, we'd be glad to help.
Yes, that is possible with either a Linear Servo or a Linear Actuator (one that has a potentiometer). I recommend using an Arduino for this application. A linear servo would be easier than a linear actuator since you would not have to purchase or learn how to use a motor controller. Let us know should you have any other questions tech@servocity.com
Hi Natan, we only have one category of actuators able to provide such length.

So that is one thing you forget to mention. It had much more dynamic and static load rating than I needed and was the correct voltage. It was slow but I would rather slow than not enough lift. Anyway, I would be interested to know what went wrong.

At 5:47 what is the part # for that linear servo ?
it is the actuator shown here: www.servocity.com/8-stroke-25-lb-thrust-linear-servo/
You guys are great together, Cracked me when you pulled out the linear servo how Jason was looking at you thinking "why is this dude trying to one up me man"
Awesome vid...does the amp of battery effect the actuator? Asking because I plan to install 2 linear actuators in my truck and debating if I should tap off the truck battery or off separate battery. Thanks
Thanks, Benjamin. If you are running linear actuators, you can tie them into your vehicle battery without a problem. The motor in an actuator won't be bothered by the fluctuation in voltage due to the alternator. More care would need to be taken if a micro-controller were in the equation. Feel free to email us should you have any other questions tech@servocity.com.
@@ServoCity awesome, thank you!!!
Very good demo.I like the contrast between you two, I actually learned a lot from two perspectives, that was very thorough and satisfying considering my obsession with finding out everything tech,especially electric motors I will subscribe and like. I love the way you get down to business, no extra B.S. I’m a K.I.S.S. fan myself, keep it simple is usually my aspect on things, I also enjoyed the disassembly, appreciate the convinces you 2 have provided and fantastic presentation!
Thanks, Tommy! We appreciate the kind words and are glad you found it helpful!
I loved the way the linear actuator moved. Way better than the servo's jerky moves.
this is what i looking for.. thanks for the video..
Glad you found it helpful!
What brand of actuator are you using in your video??
They are the actuators that we sell. We have the links listed on the top of the comments. Please let us know if you have any further questions.
@@ServoCity Thank you.
Is it possible to have it extend and retract on a constant basis?
A couple questions! What is the noise rating on the servo? Also, if I were to open the servo and move the limit switch on the fully-extended side (desolder, drill, solder), would the servo have a correctly-functioning shortened range? I'm looking to do ~85 lbs with a ~1.5" throw and it would be excellent to have the safety in hardware, not software.
Hello! Great video. Is it possible to create an automatic reciprocating (preferably adjustable) movement with a linear actuator (without having to turn a switch back and forth) and if so what equipment would one need? Thank you so much 😊
arduino
Great video, area there any problems that you are aware of regarding installing them in a hot humid greenhouse for ridge and side vent opening? Thank you.
Are these water proof or do you need to buy ones that come water proof.
Hi Charlie, our linear actuators and linear servos have IP ratings which will give you the extent of the water resistance. Feel free to contact our Tech Team should you have any other questions tech@servocity.com.
That was an awesome demo guys..I have a question..I am trying to build a scale model of an excavator using the hydraulic principle with syringes.these motors act as Pistons so I should be able to use them instead right,I want to know what torque do these motors have cause I want my excavator to dig and lift just like the real thing.are they expensive to buy and could you pls do a demo on how to convert it to remote control..tnx guys
You can certainly use linear actuators or linear servos in place of hydraulics if the speed, thrust, stroke length and overall size fit your model. Since we’re quantifying a linear force they are rated in pounds rather than a torque measurement. The amount of weight it can lift will depend on the placement of the actuator in your assembly. Prices vary based on what selection you make; we have HD linear servos which are the most plug-and-play solution for r/c. We offer HD linear actuators that are less expensive but more intensive to hook up to R/C (require a motor controller that can convert the PWM signal to a voltage that would get sent on to the motor). and SD linear actuators which are the same as the smaller ‘HD’ linear actuators but beefier for more industrial applications. The video covers how to connect a linear servo or linear actuator to a servo controller. An R/C transmitter and receiver is just a wireless servo controller so it’ll connect the same way. Please let us know if you have any additional questions tech@servocity.com
Super!!!tnx for the prompt reply!!
Another question..how does the boom of a crane extend..do they all have multistage cylinders or are they also equipped with linear actuators within each boom extension?
And i.would really appreciate it if u could do a demo on how the excavotor rotates 360degs and still powers its tracks without its wirings and hydraulics getting twisted in the slew ring.i have looked online but not really satusfued with info or the lack of detail given. Cheers bros!!
Here’s a link to a brief explanation of how a crane boom extends: answers.yahoo.com/question/index?qid=20081125153736AAiN8mW. I would have to do more research on an excavator before commenting on the rotating base; sorry I couldn’t be more assistance in that department. Let us know if you have any other questions tech@servocity.com. Thank you
How do these cope with dirty and wet environments like on a tractor bucket?
You will need to consider the IP rating of an actuator in such an application. Most of our actuators are IP54. While it depends how you use your tractor, I would suggest looking for IP67 or higher. Feel free to reach out should you have any other questions tech@servocity.com.

Can you provide links to the Proportiojnal Actuator and Controller
Can 4 linear servos be connected to a battery and a switch together so that all 4 actuates in sync?
That would work with Linear Servos, you would need a servo controller sending the same signal to each of the 4 servos. That would keep them synced up well.
Depending on the tolerance for misalignment in the mechanism, a standard linear actuator on each corner with one switch controlling them all may work just fine for you.
Great review. I have a question. If you stop it in the middle before it hit the limit switch and keep for a few hours does it use any electricity and drain the battery?
The current draw will be considerably less given the motor is going to be at idle but it will continue to draw from your battery until it's turned off of the battery is discharged. Let us know if you have any other questions tech@servocity.com.
Thanks for showing that actuator. I thought I would need a hydraulic cartridge to push something up, but that should work.
Glad you found it helpful, Ted. Let us know should you have any questions tech@servocity.com.
Great video. My question is, can I remove the cover of my "Windy City" actuator and reposition either, or both of the limit switches to stop the extension, or retraction, at a particular position? Thank you.
Hey guys just stumbled upon your channel after trying to find a solution to a problem im having. I have little knowledge of anything to do with servos and could really use a hand figuring out what i need to do what i need to do. Im trying to make an exoskeletal arm brace/ elbow joint for my mum who suffered from arthritis and had many failed attempts at replacing the joint. She now has no elbow or bone 8 inches either side of where the elbow should be. Ive figured out the rigging now im stuck on how to wire up an actuator to extend and hold in place with one button and retract and hold in place when released with another. This is a long shot and im sure youre very busy but any push in the right direction would be amazing! Thanks for your time. Karl :)
can this be use to move the handles in a hydraulic crane system?
in case of a real closed loop control, ism't it more correct to use the last stage sensor in place of in-box potentiometer?
What would happen if the power goes out in a mid position? Will it hold the position? Or will it go back to the initial position?
If you remove power from an actuator the motor driving it has no voltage going to it. The motor will stop and therefore the actuator will stay in the position it was in when power was removed.
Thanks Man, it was awesome video, I will be contacting you guys later on for assistance on my project.
Bravo and thank you very much for this video

I'm designing a gate opener. How well would a linear actuator hold up outdoors?
Actuators are very commonly used on gate openers. You'll just need to find one that is rated for the environment. The IP rating will tell you how well it's sealed up. Please let us know if you have any further questions.

What if you don't know what the feedback wires are. I have no documentation on mine as it is a used actuator
If it's an actuator from ServoCity we have documentation online that would tell you everything you need to know. If it's from somewhere else, you could measure the resistance between the wires to locate the potentiometer wires, or, open it up and trace the wires. Please let us know if you have any further questions.
@@ServoCity it is not one of yours unfortunately it is a duratron mc42-1015h. It says 115v but I thought all linear actuator were dc. Came from a old hospital bed
could the power source for a 12 volt linear actuator be a ac plug in 1 amp 12 volt car battery trickle charger ?
Thanks - and great video
If the actuator you choose pulls less than 1 amp under load then it may work. Some trickle chargers may have circuitry that keeps them from supplying voltage til they receive a certain amount of voltage from the battery they are connected to. To check your trickle charger, plug it into the wall, connect it to a multi-meter and see if it's supplying a voltage. Please feel free to reach out to our technical team should you have any further questions at Tech@ServoCity.com.
@@ServoCity Interestingly, a multi-meter does show voltage on my trickle charges But the linear actuator still won't work with any of them - must be some sort of circuitry in the charger to prevent this type of use - so I am scouring my supply of old AC-DC chargers from old phones and rechargeable tools to see if I have anything in the 12V 1 amp range
any silent actuators ??
I would like to trigger a light to come on when the actuator is fully extended. Is this possible?
Hi David, there are various ways you could go about it. For example you could use a limit switch ( www.servocity.com/electronics/components/switches/limit-switches ) that is physically engaged to turn on the light. Or you if you are using something like an Arduino or Raspberry Pi with a servo hat you could use a linear servo ( www.servocity.com/servos/linear-servos ) and a PWM switch ( www.servocity.com/electronics/components/switches/pwm-switches ) and send two PWM signals, one to control the linear servo and one to turn on the light via the PWM switch. You could also use a PWM switch with a Y-harness and linear servo to run them both off of the same PWM signal (like from an RC receiver or Arduino, Raspbery Pi etc) but the light would turn on the entire time the servo is extending and not just at full extension. Let us know if you have any other questions tech@servocity.com.
thanks you guys are awesome.

Will it work if we use a hi torque dc geared motor to drive a threaded rod using a timer belt and a pully enclosed in a hard PVC pipe/casing?
Hi Parish, yes, that's one way to make a linear servo. Keep in mind that normal threaded rod is not meant for creating linear motion but for fastening. The threads of a lead screw are cut much smoother and more consistent to create linear motion while minimizing friction. Please let us know if you have any other questions tech@servocity.com.

What kind of weight can this hold?
Hi Jonathan, there are a lot of variables that come into play. In general, the weight an actuator can hold is greater than the amount that it can move. The amount that it can move is heavily dependent on the ratio you choose. Feel free to contact our Tech Team should you have any additional questions tech@servocity.com.
You didn't open up the linear actuator.. I wanted to open up mine to change the position of the limit switch.. Would you recommend to do so?

Anyone know what brand or model that linear servo is? Looking for one very similar... Fairly quick with roughly an 8 inch stroke
thanks man! i just have a question, what do you call the gear that moves the threaded rod up and down?
The threaded rod (lead screw) gets rotated, it has a lead screw nut which moves up and down along the lead screw as the lead screw rotates.
First it's not up and down. It's in / out or extend / retract.
Next the screw rotates, it doesn't move in or out. The lead screw nut is what travels along the lead screw and Push Rod / Extension Tube is attached to that nut.
The gears that drive the lead screw are a combination of a worm drive/screw that drives the rest of the spur gears.
OOPs My apologies. The one he is showing here does not use a worm gear. It is just a set of spur gears.
I am looking for some ideas as to how to build an old school arcade driving cabinet like Out Run where with the turn of the wheel, the base would move. I am thinking about putting an actuator or servo, I think 4 will do the job. But what I don't know is where to start or look for. Would something like these work at high speed sensitivity and would they handle the weight? I originally was looking at hydraulics, but outside of weight, they would seem slow. Suggestions?

Dear Servo City, that is very helpful video, many thanks!!
I have one question though, is the any way to vary the output force of the actuator?
The output force can be varied by changing the voltage or limiting the current supplied to the motor. If you want to have even more control there are force sensors available that could be used in conjunction with a motor controller as a closed loop system. Please let us know if you have any other questions tech@servocity.com
Is there a servo or actuator that is big enough to reach 8-10 feet? Or something that can reach close to that height? Working on a project for wireless surveys and need something like this to add to a pi
There are some very large linear actuators on the market, but I doubt you'll want to tote something of that scale around given the weight that is likely to be associated. If you take on building something for your application you might get some inspiration from an extension ladder; pull the rope and it extends out. You could use a motor to reel in the rope or cable that you use to drive your assembly. Feel free to email our Tech Team should you have any other questions tech@servocity.com.
how much axial load can the rod take and how much torque does it create at the o/p...
Hi Sayan, the HD actuators are rated for 500lbs static load so far greater than the amount of thrust they can exert. I'm not sure what o/p means - if you can restate your question i'd be glad to help.
Nice, educational video. Thanks.

I was looking at repurposing some adjustable bed linear actuator but the wire has a multi-conductor plug with 4 pins. Why? Can I convert this to be 2 wires like the actuator in your video. I can't wrap my head around why there's more than two conductors in the plug. The linear actuator doesn't do anything but go in and out to lift bed up and down. So why so many pins in certain bed actuator? I've seen some with 4 or 5 even 6 pin plugs on some. Can you explain why a simple motor would need so many condutors in the plug?
Hello!
We are not sure why your unit has 4 wires unfortunately, it is possible it is not running a standard brushed-dc motor. Something like a brushless DC or Stepper motor would require more than 2 wires to operate most likely. It's also possible that the additional wires are some kind of feedback device. Our actuators for example have 2 power wires, and a 3 wire analog position output set. So 5 wires in total.
@@ServoCity I thought that could be the case.
I think I will get the info off the actuator and see if that will help me find out anything more.
Also I'll probably have to carefully cut back the wire cover and see how many wires are on the actual wire part after the plug.
I was hoping to avoid having to do that but I guess I'll have to and test wires with my multimeter.
Do you HAVE to hook up the extra wires for feedback? The bed controller I'm trying to use is better in every way than my current controller but the difference is the plug on the actuator motors.
The new control box has just two wire sockets for motors but far more programming options than the much older box that has 4 pin plug. I don't see why there would be feedback wires. The original controller didn't even have massage or any other features save for "all flat" and two memory locations, so I don't think the extra pins are being used for feedback on such a basic model and old of bed. But I could be wrong. And if feedback wires are there, do I have to use them if the new controller doesn't use them?
These are the questions that keep me up at night lol.
I'm hoping that it's just two wires after the plug but like I said I will have to do some testing it looks like.
And if I don't have to use the extra wires, then I won't.
Do you know anything about not using the feedback wires? And just the motor power wires?
UPDATE... Additional info. The model from the label says fd24-a4-320.400-c12-p0
I looked up the specs hoping to find info on a pinout but nothing. I did find out what those codes mean and the very last "p0" denotes the basic version with no "Hall Sensors" which I assume means feedback sensors. Because they can have one or two and the code would change to "HS1" or "HS2" accordingly.... Which again "p0" means no sensors
So it's looking better and better that the extra pins are not being used for feedback sensors.
Some cool information!
I would agree that it doesn't sound like the extra feedback wires are being used.
Please feel free to reach out to us via email or phone with any more info, but from what it sounds like they are extra and most likely there are just 2 wires that are being fed 12v actuator power. Most actuators are fully capable of running without their feedback device being read, it just allows more complex control of the unit.
@@ServoCity thank you for helping me to believe that my initial assumptions could be correct.
One new thing I learned.
I was facing a similar situation with the plugs on the massage motors. Again the sockets on new controller were two pin but the massage motors I picked up were 5 pin. I took the massage motor casing apart, reasoning to myself that these are nothing more than simple dc motors. Why on earth would you need 5 pins? Turns out you don't. The wire inside the casing and soldered to the motor was only 2 wire.
So far my quest to put together my own upgraded adjustable bed is going wonderfully. Hope the linear actuator problem goes just as easy when I test those next.
Thank you again for your help!

If your still around I would like to ask a question. I have an actuator that has stopped working (extending and retracting) and need to raise (retract) the shaft to its shortest length. What would be the simplest way to do this manually, if possible?
It depends on the design of your actuator, but if you can access the lead screw driving the piston, just rotate the lead screw manually (assuming it will still turn) to manually extend/retract. Feel free to contact us should you have any other questions tech@servocity.com.
Is there any way we can get benefits of servo actuator in linear actuators with some simple additions or changes.Secondly what's cost difference in general? What's the max speed force and stopping accuracy of each of them?
You can create a linear servo on your own using a linear actuator and a motor controller that has positioning feedback. Cost is dependent on what components you select for your project. Speed is dependent on the ratio you use and accuracy is going to come down to the stroke length of the actuator (as that will somewhat determine the resolution from the potentiometer) and the circuit board you choose to drive it. Email us at tech@servocity.com if you have any other questions and we'll assist you.

Thanks, Phil. We're glad you found it helpful.
good info and good video. Now if I wanted the servo or actuator to just keep going in and out on its own but be able to control the speed how would that be done. To add another option if I wanted the auto function (the in and out on it own) with speed control then switch it to be able to control position. how is that magic done? any info you have or if you can point me in a direction. please.
Hi Darrell, sometimes a rotating assembly (think crank, rods, pistons in a car engine) is a preferred setup for linear motion that runs continually. This will keep from having to ask the motor to change directions over and over so your efficiency can potentially be better. If you want to use the actuator I'm sure there are many ways to do it electronically - one of those ways would be to slightly rewire the limits and include a latching relay that would allow it to change direction when either limit is contacted. If it's a linear servo just have a controller with a program to tell the servo to go in and out at whatever rate you want. Note you're using the position control to control the speed in this setup but it works just as you've asked. For the position control setup you've requested while using an actuator, a motor controller with a feedback loop could be used and a program could be written to precisely control the position of the actuator. Or if it's a linear servo just have a program sending the PWM signal to the linear servo (much like setup 1 using a linear servo) but have a manual mode where you can adjust that PWM signal with some form of input (potentiometer for example). Let us know if you have any other questions tech@servocity.com.

Glad you found our video helpful, Braulio. Yes, a linear actuator or linear servo is capable of actuating the clutch on a vehicle.

Is there any way to program one to go in and out to a certain point with only a button?
Yes, that is possible with either a Linear Servo or a Linear Actuator (one that has a potentiometer). I recommend using an Arduino for this application. A linear servo would be easier than a linear actuator since you would not have to purchase or learn how to use a motor controller. Let us know should you have any other questions tech@servocity.com
