- 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.
😂
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.
Great presentation, including the final fuck up, which added a nice touch to the video. Keep it up!
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
Lol, it was at this moment, that he realized, he fucked up.
That camera focus is wild
Really great vid to demonstrate calculated concepts practically!
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!
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.
Thank u for better practical explanation.
Thanks for the best video every thing clear in 5 min
Understand thanks again
6:18 sehr schön! xD
Und direkt mal der Beweis, dass da einiges an Gewicht dran hängt.
Und super Video!!
Thank you for this presentation.
That was awesome man! Made me laugh so hard! And thanks for the info!
😂 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 😂
Sustain the great job and generating the crowd!
This was great! Coming from a fellow beer fan lol. Earned yourself a sub!
06:16 😉 this is why proper arrangement is necessary.
thank you for the video
...slowly moving towards the metric system... inch by inch :-)
Danke. where did you buy the 27:1 gearbox?
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 for the info. Great video. Loved your creativity + commentary 😂🤣😂
Nice Presentation
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?
Bravo. Amazing explanation. Great for us beginners.
Dude I almost choked on sushi , Twice , thanks to your dry ass humor. Well done.
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
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
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.
Nice work, thanks.
Great video...informative
Exactly experiment ❤
Unexpected climax
How did u make the lever that attaches to the shaft of the motor
Do you even manual focus Bro? Seriously though, great concept.
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.
Thanks a lot for this video ! its very helpful my friend i understand now
good explanation...
Interesting demonstration brother...
Thank you. Really good vedio ⚘
6:18 that moment I got shocked
6:20 That's my default brain setting. I'm more likey to break something than fix it.
Good video, but use manual focus on your camera
Hi, does anyone know where that datasheet he referenced is located?
thanks bro
You made me laughing..while watching serious😁😁
I would like you to give me the code to control the motor with the joystick
MAXIMUM WEIGHT CAN IT LIFT
PLEASE SUJEST ME TO USE A BEST STEPPER MOTAR FOR LIFT 30KG OF LOAD
Sehr gut, vielen Dank!!
At the end, everything goes down...lol
But very informative video...thanks.
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 ????
is this capable of controlling this using arduino or raspberry pi microcontroller
So, if he had placed the weights at 1cm from the shaft; will the motor have no problem lifting the weight?
Moving towards the metric system....inch by inch. hahahahahahaha XD
you use votage 24 V? Please sent me to know
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
jajaja I think everybody lol at 6:19 thanks for the vid
what is the 0.36 Nm?
...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?
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!
thank you!
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 :)
Thanks! Though, please please please use a better camera, or at least a camera with better autofocus! :)
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?
:( This video looked like what I was looking for but I'll never know cuz I cant hearrrrr
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?
Thanks so much!
The moment he fuck#d up was soo funny, good video mate, thank you mate
BRO! Do you even level the audio?
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.
What stepper motor under 10$ will be good for robotic arm
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...
so i need to lift 10cm 4kg , which means that the arm will be 5 cm long ... lol so nema 17 is not the good choice .. wth motor i need ? could you help ? If i calculated it right i need 1.96 Nm . so nema 23 which has 2.2 Nm should be ok ???
🇺🇸🇦🇷🇮🇱 good test to know that I have to buy a bigger motor 👍
you have to put your camera focus to manual but im sure you know that by now
Thanks but where do I get that black arm?
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?
I would like to adjust the engine revs using various buttons, does anyone know if this is feasible?
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.
The motor for camera focus is jealous for sure...
Can you please answer this,
If the stepper motor had lifted load to almost 90 deg and we lose the power will the motor rotates back to its 0 deg. position due to the gravity or it holds its position upon power loss.
I want to use a non geared stepper motor in one of my project and i want a fail safe design which returns to its initial position upon power loss.
Thanks in advance
Hi Abdul, sadly, if the power is cut, the weight will pull down the lever again. You would need an additional mechanism to keep it in the 90 deg position on power-loss.
great vidio
how much power does a typical nema 17 stepper motor require?
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
How strong would be a nema 23 56mm with 10:1 gearbox? Im wondering if its strong enough for my project
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.
Which brand did you test?
That scared the piss out of me….. lol
What camera is being used for this test? The constant refocus makes me think it may be a Surface webcam.
This was a Nikon D5000, I noticed too late that the autofocus is horrible. All videos after that I took with fixed focus. I am still searching for a good (and cheap) DSLR with better autofocus..
hey can you help me to find motor for my project, i need motor which can push the car break paddle need 4kg to start to push it and need 8kg to push completly can you suggest matching motor for this
This sounds like an interesting project :) I can try to help! How would you want to move the pedal? With a lever? How long does it need to be? How deep does the pedal need to be pressed?
@@labstream4122 4.5cm it will move to applying fully break , this the length move ,
@@labstream4122 i try to use flexible connection (like cable or wire ) between motor and paddle , because it free to if driver need also he can manual control the break paddle push .. this connection help to both motor and driver can control the paddle ,
@@labstream4122 15sec enough hold the break paddle , motor axel and paddle connect with wire and after motor rotate, cable roll around motor axel , and paddle will pull to down
@@shanukajothirathne4267 If you want to move 8kg, we are searching for a motor with roughly 1Nm torque - that would give us the ability to move approx. 10kg with a lever (or in your case - a wire) up to 1cm away from the motor axle. I have seen some Nema17 that claim that they provide 1Nm of torque, but never had one of these here. A Nema23 would probably be a safer bet. If you really plan to put this in a car, space might become an issue, though? And what are your requirements on the speed - how fast should it be able to pull?
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?
Hi! Were they tested at full step?
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.
Thank you
