you guys deserve a comment for every view. no one will leave the video without learning at least something. please keep doing this good job.
Thanks a lot, Ayesh!
Perfect timing. I was just talking to tech support of a servo company today to spec out a motor. Thanks.
Great! Happy to hear.
Such a comprehensive and massive detail, I have never seen before thanks a lot.
Glad you liked it!
i like how people like to complicate simple things with Engineering terms, if they just talk plain simple as we used to speak when we were kids this explanations would be alot better
Great Information I have been searching for this for a while now...
Great to hear that you have found it! Happy learning!
This is pure gold you just turn very complex principles into a very beginner-friendly format, what a master piece !
Thank you!
The real video and best information about motors , to design your motor
Glad you think so!
I can't but appreciate the effort you people are putting 😊.
Thank you very much!
A very detailed and informative video, thank you.. I love your channel, it's so convenient for the project im currently working on. Can you please help me with the name of the software you used for calculations.
I am not sure of the specific software used in this video, but there are several out there that can be used. Just search for "software for sizing servo motor" in your browser. A couple that are useful: www.orientalmotor.com/motor-sizing/index.html; www.jvl.dk/713/motorsizer
Sir , would make video on how to determine motor size for Belt conveyor (induction motor ) . Or any other type of application on induction motor
Hi there, I will pass your request on to our creator team.
@@realpars thanks a lot
Id love to see this too! Thanks
Thank you for your training.
You're very welcome!
Thanks.
Thank you very much for your training!
You're more than welcome!
This is an amazing video. Thank you so much. and I start to follow you
Awesome, thank you!
Thanks RealPars team for this video.
You're very welcome!
@@realpars please make video series on PID.
3:52 wrong, the more ENERGY will be needed. energy is force multiplied by distance, so counter-force does not necessarily need to change to counter the change in mass; the distance of travel could be the factor that changes, and most likely would be the variable since friction (the main counter-force) usually remains constant.
When two objects interact (puck and ice), each one exerts a force on the other that can cause energy to be transferred to or from the object. The puck exerts a force of mass x gravity on the ice, and the ice exerts a frictional force (albeit relatively small) on the puck. And you are correct, it is the transfer of energy that causes the puck to eventually stop.
Really helpful in selecting an Motor!
❤ thanks a lot
Our pleasure!
Nice video, but I didn't see an explanation for what the 'e' value is (distance from axis of rotation to G) Perhaps G is the centroid of the arm?
Yes; e' is the distance from the axis of rotation (horizontal) to the centroid of the rotating arm.
@@realpars what if e=0 ..the shaft is at the centroid will it work?
Hello there! Thank you for your nice presentation and explanation. I would like to know how I can use a stepper motor with a lead screw in pushing a mass of 10kg linearly. I mean the coupler and all the equipment with necessary equations I need to come up with. Please help. Thanks.
Hi Sai!
Thanks for your comment and your suggestion. I will pass this on to our course developers!
Thanks for sharing and happy learning!
Good day, I want to cut a 4" PVP pipe. May I ask the process/computations in order to know what is the right size of motor for it? Direct cutting from motor to blade to pipe.
I assume you meant 4" PVC pipe. I cut PVC pipe with my 1/2 Hp reciprocating saw without issue.
sorry for the mistake. Yes, do you have a video or link in computing for finding the right motor in order to cut it? Like the steps in determining that you have chosen a right motor for it.
Phenomenal video!
Thank you!
Any recommendations on servomotor brands? I'm in south America and Allen Bradley and Beckhoff are way over budget
The market may have changed because of COVID-19. Depending on your application, size and package types will vary with manufacturers as you may already know. Also, you may want to consider stepper motors and watch the RealPars video ua-cam.com/video/VfqYN1eG9Zk/v-deo.html, to help you make the correct choice. Here are few manufacturers to consider, that indicates they have support in S. Africa, (I do not endorse any of the following companies, however, they have been in the industry, worldwide, for many years):
Kollmorgen: www.kollmorgen.com/en-us/where-to-buy/
Omron: industrial.omron.co.za/en/products/servo-systems
Oriental Motors (support form Europe): www.orientalmotor.com/company/global-support.html
Excellent. This was really easy to follow and should allow me to spec the right motor for the project I'm working on. Many thanks. Subs +1.
Great to hear that! Thanks for sharing your positive feedback with us!
Very good lesson.I exception this lesson
Glad to hear that!
Thank you for this video! It's very nice.
Thank you Javier!
Nice and very clearly explained video...Keep it up👍
Happy to hear that, Asvene! Thank you!
Love it...thank u
You are welcome!
When I open the software, I get the error:
"
invalid conversion of the string"7.9" in typ single" "
I tried to repair it but it didn't work
This appears to be a software error caused by an issue with the specific browser you are using or the absence of some software component that was not loaded correctly. I am not sure exactly what software or version you are using, but I would contact the software vendor via their support website.
Hey Marcel, did u fix it
Great job 👍
Thank you very much!
fantastic video
Thank you!
Hi Mate,
I am going to carry a steel pallet (overall weight of 700 kg) over rollers with 2 stepper motors on each sides, do you reckon "Nema 42 CNC Stepper Motor Bipolar 30Nm" is enough for this application?
It will likely be sufficient. If 30Nm is the torque developed, this will likely work with a 1500 RPM motor. The duty should be rated then for 6.5 amps or greater. Even though you have four motors, I would still calculate based on the unlikely event of one motor on each side failing.
Much appreciated!
You're very welcome!
thanks Sir
Thank you very much.
Sir, please provide a video to how to select 3 phase induction motor to particular load, with manual calculations..
Thanks for your topic suggestion, I will happily go ahead and pass this on to our course developers.
@@realpars thank you so much sir...
Excellent!!!!!!
Thanks a lot!
This, was very useful...thank you.
That's amazing to hear, thanks for sharing!
Hello, dear RealPars! Thank you a lot for very informative and useful videos. Subsribed long time ago.
I am going to start a project where servo-motor is supposed to be used to drive gear pump.
Would be thankful for any advice how to select a proper servo-motor for this purpose.
Good topic and as usual great job.
Thanks a lot, Kenny! Happy learning!
Thanks very much ...🌺🌺🌺🌺🌺
Most welcome!
Sir could you make me understand.if we are using 2 motors and each have 155kw capacity so what will be the sum of both motors power. It will be 310 KW or anything else 🤔
What are you trying to do? Connect two motors in series? In parallel? AC or DC? Or do you want to connect two pumps with independent motors in series? Parallel? Add some context, since the answer is different in each case. For starters, you would not electrically connect 2 AC motors in series for any reason. Each will run at reduced voltage and ultimately overheat without producing any more useful work than a single motor.
that s great ,god bless you , send link for downloads software .
Thank you very much! You can download the "Motor Sizing Software" we are using in this video, here:

Kindly add an english subtittle for your video.. So that its more clear to understand.thankyou
Hi Eugene,
Thanks for your comment!
You can turn on the English subtitles by clicking on the CC bottom on the right side of the video.
Hope this helps, happy learning!
how to configure Absolute encoder in PLC and if encoder is replaced then do I need to reconfigure?also, will the length of connecting cable have any effect on configuration?
Encoders are configured in a PLC in many ways. The best way is to use a separate servo motor controller, as shown in the video. The configuration of the encoder is handled as part of the servo controller setup. Absolute encoders typically send voltage signals in a serial data stream via a protocol called SSI. Siemens makes an SSI encoder interface card (6FX3002-2DB30-1BF0) that is not very expensive. The card can be configured to meet the specific resolution and parameters required by your encoder. Some encoders come with a more advanced interface, such as ProfiNet, so they can be directly added to your hardware configuration and configured using special OB blocks developed for interface to the device. If you swap out encoders later on, no additional configuration is required as long as it has the same interface, resolution, signal frequency and voltage level. Otherwise, it may require changing some of the parameters in the encoder interface. If the encoder has a serial (SSI) interface, then cable length is only an issue once you approach about 16m (50 feet).
ThanksActually the encoder being used is yes an SSI-P for PROFIBUS (10-30 Volts) and comes in 2 models, one to be used with 10m cable (33FT) and the other model used with 30m (90 Ft) cable.so my question here is; if by accident they where swapped as encoder; 10 meter model used with 30 meter cable and the 30 meter cable was used with the 10 meter cable what would be corrective action to be done at the resistance terminator or at the PROFIBUS?
thank you for the training
You are very welcome!
Recommend 750w servo motor www.aliexpress.com/item/32326080829.html
which software is this on which u are calculating size of motor?
Hi there,
Thank you for your question! This video was created four years ago with Omron drives. Not sure what version was used, but I am sure it’s been updated. Therefore, I can’t be sure which software version was used. But you can go to their website and find the drives product line. Companies that make drives provide the software too at a cost. However, you might find some free ones with limited usage. You can check any major motor manufacturers line like Siemens and others.
Hope this helps!
i want to spin a 55 gallon drum about 30 rpm any recommendation on what kind of motor i should use. ( would prefer to be able to plug in to the home outlet)

James its best to use a sizing software from any of the servo motor companies online.
Can I lift 10kg weight by using 48 DC volt motor? If yes, how much torque and power I need for that?
Power = force x velocity = Mass x g x velocity. If you want to lift the weight at a rate of 0.1m/sec, then a 10kg weight will require P = 10 x 9.81 x 0.1 = 9.8W, not accounting for friction or other losses. Assume losses are 50%, so your motor will need to deliver about 20W of power.
Torque will depend on the way you are lifting the object: screw jack, ball screw, rope and pulley, etc., so it will depend on screw pitch, orientation (lifting vs. levering), pulley diameter, etc.
A 48VDC motor will do the trick provided it can deliver the required power at the required torque to lift the mass.
@@realpars thanks a lot RealPars 😍🌹
Could you please also mention where can I download this software for motor sizing?
You can download the "Motor Sizing Software" we are using in this video, here:
bit.ly/2DlK8E2
awesome job really helpful ! so is the software motor sizing still working ?
Yes! Although more recent versions of the software have been released (as more motor models are supported, the physics behind servo motor control remains the same. For the same load, torque and other parameters are still important and are calculated in the same way.
@@realpars yes i download the setup from orientalmotor's website but after complet installation error occurs when i try to open the software... any help ?
Which animation software do you use to make such good animated videos...
Hi there, we use Adobe Premiere Software for our videos.
How do you guys make drawing for this video what software?
Thanks for your comment! I am actually not sure about that as our courses are created by our Graphic and Animation department.
Sir, u have given very useful training.
You are very welcome!
Helpful.
Glad it was helpful, Majed!
Please provide us basic PLC program for ac servo motor....

Thanks!! Perfecto btw
Thank you!
I want to ask you
can you upload courses about Siemens DCS SPPA-T3000 ?
thanks
Hi there, I will ask our creator team.
@@realpars thanks
Because I find it very important in industrial automation especially in power plant field
Can you provide similar advice on using a dc motor? If not can you direct me to an expert who could thanks.
Hi Andrew,
I will ask our creator team to add this topic to our list, thanks for the suggestion!
Happy learning!
Awesome as usual!
Thank you!
Thanks for the information pretty neat. So,
Bigger gear ratio = Less speed, more torque capacity and less inertia ?
Best regards
Yes. See the video at 12:25.
sir can you make a pdf of this information??
Hi there,
Unfortunately, we do not do that. All our courses are in video format, that way it is easy to understand and follow for anyone :).
Happy learning!
Hi sir could you give ur link for software to calculate Motor size ?

what if the rotation is 20degree angle?
Not a problem. Be sure to use the resolver feedback to position the part where you want it to be.
@@realpars What about the Pump motor of Concrete mixer truck?
Is this a mechanical or electrical engineer's job to figure this out?
Normally, an electrical engineer will determine the size and configuration (HP, voltage, FLA, frame size, grounding, etc.) of a motor, and mechanical engineers will be responsible for the mounting base, supports, and shaft alignment of the motor.
@@realpars Well thanks for your help. guess this does fall within my responsibility to learn about.
You are very welcome, Wail!
