Selecting the right stepper motor - Torque test of Nema17 and geared Nema17
Вставка
- Опубліковано 6 жов 2024
- In this episode we talk about how to convert the torque specifications in Newtonmeter to something more graspable, like kg/m, or lb/inch. We look at the datasheet of a Nema17, and field-test our conversion with different weights. A 27:1 metal-geared Nema17 will also be put to the test, lifting 2.5kg.
Schematics, code and graphics can be found here: github.com/Lab...
I am quite new to producing videos, so I am super thankful for tips, comments and suggestions on how to improve!
(P.S.: I noticed the irritating focus-behavior too late, next time I will set it to manual focus)

“The US is slowly moving towards de metric system. Inch by inch” 😂
Genius
😂😂😂😂😂
Genius
Remember the blunder where it cost a plane to crash because of the metric system? Probably not. Those who don't read history are bound to repeat it.
I'm in the US and can't wait. Love America, but the imperial system is just a hassle. It's time for us to convert.
6:19 will forever stay in my heart.
I read the comment before and thought I was ready! Almost dropped my burger.Still laughing.
😂
Lol, it was at this moment, that he realized, he fucked up.
Great presentation, including the final fuck up, which added a nice touch to the video. Keep it up!
I actually knew it was gonna happen, even before you put the weights, just by looking at the clamp, and I was thinking "what is this guy thinking, it was obvious it wasn't gonna hold the weight".. But that was a great demo. At least no foot was harmed.
Thanks, you make me laugh too much in a moment that i not spectate. Nice video. Thanks for share.
Wow! That was a ... nice(!?) video? You gotta have a look at your autofocus - use a fixed focus instead. Greetings from Germany - you just got a new subscription
Awesome video! It would be interesting if u make some tests to analyse the Torque x RPM curve too
Loved the video!
But yea, the autofocus was going crazy. I dont know how to fix that but i would love you to do more on motor reviews, part reviews and how to for diy projects! You earned another sub!
Really great vid to demonstrate calculated concepts practically!
Haha, great video! And actually the first useful one that I've found on the topic, thanks!
Great video and information. Thank you.
Was searching this. Got this and understood clearly. Appreciate the Great work. Thanks a ton.
Thanks for the best video every thing clear in 5 min
Understand thanks again
That camera focus is wild
Thank u for better practical explanation.
That was awesome man! Made me laugh so hard! And thanks for the info!
6:18 sehr schön! xD
Und direkt mal der Beweis, dass da einiges an Gewicht dran hängt.
Und super Video!!
Thanks for the info. Great video. Loved your creativity + commentary 😂🤣😂
😂 I f*n knew something was going to go! Was surprised at the motor power, well done, but my instincts told me something was guna happen. Funny one lads 😂
Thank you for this presentation.
Bravo. Amazing explanation. Great for us beginners.
This was great! Coming from a fellow beer fan lol. Earned yourself a sub!
Nice video. I'm wondering how bad the backlash of the stepper with the gearbox is? This would drastically influence for example the precision of a robotic joint. Were you able to feel any backlash or did you measure it?
good explanation of motor torque capacity. just can u make a video for holding torque once we switch of the power supply. NEMA 17 n NEMA 23
Sustain the great job and generating the crowd!
Interesting experiment. However It would be also useful to measure the current draw by the motor to better assess the ability to lift within the rated current.
Maybe if you'd sat a bit closer to the camera, the autofocus and the sound (low volume) would have both improved.
Hi, Thanks for your input! I am currently working on a better setup, so the next videos will be better :)
@@labstream4122 👍🏼. I'm amazed you're still replying to comments on a two year old video. 😂
Thanks a lot for this video ! its very helpful my friend i understand now
Dude I almost choked on sushi , Twice , thanks to your dry ass humor. Well done.
Great video...informative
Nice Presentation
Nice work, thanks.
Do you even manual focus Bro? Seriously though, great concept.
06:16 😉 this is why proper arrangement is necessary.
Danke. where did you buy the 27:1 gearbox?
...slowly moving towards the metric system... inch by inch :-)
thank you for the video
good explanation...
:( This video looked like what I was looking for but I'll never know cuz I cant hearrrrr
Thank you. Really good vedio ⚘
Exactly experiment ❤
At the end, everything goes down...lol
But very informative video...thanks.
...love the meme :) nice video...
Looking into stepper motors to make my cars tailgate automatic lift/close, still deciding between Nema17/23...
Would like to see how much torque can stepper produce over the shaft?
Unanswered questions (1): Was the slippage due to mechanical failure of the motor shaft to lever connection? (2) Was the slippage due to the motor being unable to lift (e.g. failed to maintain lift)? (3) Was the motor able to "hold" the weight? (4) What demonstrates the failure of the motor? (5) how to calculate which motor to choose for which weight.
Good video, but use manual focus on your camera
Sehr gut, vielen Dank!!
Thank you for the movie, I was hopping to see if the nema 17 kan lift up to 4kg? The movie sound is to low, if this kan help you in the future :-).
Hi, thanks a lot for your input! That depends on the NM it is able to produce. 0.4Nm of torque means it can move 4kg attached to a lever that is up to 1cm away from the shaft. However, for long-term operation it has to be checked how much radial load the motor can take. It might have to be decoupled from the load. I am currently looking for ideas for new videos. If you can provide more input on your specific usecase and its requirements, I can try to test it and make a video from it if you are interested?
Interesting demonstration brother...
The disclaimer at the end: No motors or microcontrollers has been harmed during taking of this movie... You made me laugh a lot.
I am also curious what voltage did you supply to the driver for achieving this, is it 12v, 24v, 36 or something else?
Thanks! Though, please please please use a better camera, or at least a camera with better autofocus! :)
6:20 That's my default brain setting. I'm more likey to break something than fix it.
So, if he had placed the weights at 1cm from the shaft; will the motor have no problem lifting the weight?
Thank you for this good video!!!
I have a motor with a holding torque of 4Nm here, according to your calculations this should lift 40kg at 1cm, correct?
thank you!
Thanks so much!
you have to put your camera focus to manual but im sure you know that by now
MAXIMUM WEIGHT CAN IT LIFT
PLEASE SUJEST ME TO USE A BEST STEPPER MOTAR FOR LIFT 30KG OF LOAD
great vidio
thanks bro
I use a NEMA17 with 0,59Nm and when I mount a simple RC wheel the motor slips. No force to move my robot car :(
I use the A4988 Driver. In so many projects the steppers looks so strong.
Intresting video, I'm doing some research for a project and could use some help. I wanna use a stepper but the only way to get power to it would be a battery pack charge by solar or something like that. The torque of the 17 looks good but I might go for the 23 just to be sure... But I want to know... What kind of battery pack would I need to move 4 linear meters on full torque (worst case).
Hi Bjorn, that sounds interesting! Could you write an email to me, I can look it up tomorrow?
jajaja I think everybody lol at 6:19 thanks for the vid
hope your motor is fine ...
I would like you to give me the code to control the motor with the joystick
Appreciate your video, I am making a crane using a stepper motor. It works up and down perfectly. But I cannot pause in a position in between with A4988 driver, will this driver will do the task
It would be very good to know how much voltage was set in you power supply and how much current was set in your BL-TB6600-V1.2 driver?
I do realize that, and I am already working on the next video, have also built a new and better contraption to test different motors, and will definitely use your feedback! If you can think of anything else that would be interesting please share and I will try my best to consider that in the next video!
@@deSpeyer Thank you for your answer, I am really looking forward to watch the video.
What stepper motor under 10$ will be good for robotic arm
You made me laughing..while watching serious😁😁
Moving towards the metric system....inch by inch. hahahahahahaha XD
Thank you
The motor in your camera is acting up. Turn auto focus off and use manual
thanks for the testing video I need one help as i am unclear . I want to rotate the mechanical knob which need 5nm torque to rotate. which stepper motor i can use ? should i select the motor in accordance with the holding torque specification or something else. Kindly reply
use manual focus or single servo
The moment he fuck#d up was soo funny, good video mate, thank you mate
I'm here because I'm asking myself a question, is it really necessary to have nema 23 for a CNC?
taking into account that they only have to move an engine on axles made of aluminum ...
can nema 17 have enough strength to mill brass, copper, aluminum etc in complete tranquility?
How did u make the lever that attaches to the shaft of the motor
my stepper not lifting load having 10 cm link but roatate load if i place it on stepper shaft ? so why stepper is doing this
Unexpected climax
Hi Sir, I was planning to build a DIY 3DOF full motion for my flight simulator, the weight payload is about 150-200kls. Would you suggest what type of gear motor that fit my plan? Your comments are really much appreciated. Thanks in advance :)
The motor for camera focus is jealous for sure...
hi i need help , i have designed a door n weight is aprox 4Kg and i have installed 12.5kg stepper motor n its unable to open or close ????
Fuck I actually jumped when the rig fell 😅
Hi there, does the distance of the string from the shaft make a difference to how much the motor can lift? I am interested in using a servo motor with a torque rating of 25 kg-cm to lift a mass of 450g, 20cm away. Could this work with a string or not?
Thanks.
As long as it hangs parallel to gravity it does not make a difference, the force 'pulling' on the shaft will be the Same regardless of the length. The motor you proposed seems fit for your application! May I ask what you plan on building?
@@deSpeyer Hi there, I'm trying to make a device to pull someone's fingers open as they cannot do this themselves. Using the servo as a sort of precise winch I guess.
Would it work horizontally?
@@kyle_vr yes, this should work. Sounds like a very cool and important project! If I can be of any further help let me know (I am the guy from labstream, accidentally posted with my private account)
@@deSpeyer Ok, thanks!
how much power does a typical nema 17 stepper motor require?
Could the stepper motor be "inversed" into an input device ? Meaning you turn the motor manually and read the position (angle) from a computer program. (This could be useful to build an "input puppet", posed manually. Then the pose will be duplicated into a larger/stronger device).
For anyone reading this question 2 years later, you can just use potentiometers in the input joints to get analog readouts, run-through arduino and get your angle.
Good information
i am building a linear slider with the help of Hybrid NEMA 17 will it be possible that it can pull 5 kg weight with the help of
lead screw on linear slider????
please guide me.
is this capable of controlling this using arduino or raspberry pi microcontroller
Hi, does anyone know where that datasheet he referenced is located?
BRO! Do you even level the audio?
Thanks but where do I get that black arm?
I want to make an "elevator" at the end of my bed, that can lift a 60" LCD TV (I don't know the exact weight). But I don't want to spend more than $350~400 on motors... or miss the show while the TV is being lifted... xD
Any suggestions? 🙂
Get an electric linear actuator of desired stroke.That will be simple and easy.
What height does the tv has to be lifted?
One way is to make a scissor lift mechanism ..
Also try car wiper or car window motor (used probably) .. or some other motor ..
Also add end switches for safety ..
you use votage 24 V? Please sent me to know
🇺🇸🇦🇷🇮🇱 good test to know that I have to buy a bigger motor 👍
Good channel. Pls use a mic
What kinda of secret tech is that nano? redaction attempts at 3:38 ?!!?!? ;)
Haha, I did not notice that during the final edit :) This is another failed attempt of Pinnacle at tracking an object to have text beside it :)
I'm looking for peak torque from start, which steppers don't do, but servos will. Do you have any suggestions or places where I might find one making at least 4500rpm and at least 1lb-ft of torque? Any higher numbers of either one are preferred, but that is the absolute lowest I can allow. Please let me know if you can.
Sir please reply me, I'm making a college project, CNC EDM , a screw have to rotate very small rpm , and it's lifting a weight 15+ kg which is attached with the nut , which type stepper motor is preferable in low budget...
6:18 that moment I got shocked
I want to use two stepper motors to power a wheelchair for a friend. He weights 90kg. Do you think the shaft of these motors can handle that amount of weight? Also I'm thinking of going for a Nema 34 just to be safe with the min. torque required for the job.
Most probably not. I'd suggest to put the axle with the weels in bearings which can hold the weight and drive this axle using a belt or a chain
