Videos like this saves me a ton of hours learning.. Keep the great job

This channel is great, always something actually new to learn! Other channels just cover the same old stuff I worked out as a kid (lift, basic electricity, basic powerplant etc).

The clarity of the explanation reflects the depth of your knowledge. Your graphics team has worked hard too. You deserve every penny you get. Well earned!

An amazingly explained video, you guys earn every penny that goes to your patreon.

Very well explained, thanks.

PERFECT explanation as always. Thanks!

Brilliantly explained and finally I understood how,what & why of Stepper motors and its applications. thanks

As one who used steppers in my CNC, it is VERY interesting to see the design intent contained within.

The most clear explanation videos from what I've seen!

Thank you for everything! At first I was skeptical of the slowness of your explanations. Now I appreciate that!

I have worked on many industrial robots at an automotive company, All used servo motors with encoders attached and harmonic drives. The harmonic drive is a very high ratio speed reducer and doesn't use gears so there is almost no play, The encoder is hooked directly to the motor shaft, it consist of a thin wheel with small perforations and a led on one side and light detection on the other. As the motor turns the light going through the perforations are read and counted. So when the robot goes from point a to point b the encoder keeps track of the number of flashes there probably is a 1000 or so perforations around the disc so even a very small fraction of a rotation is even monitored. So to repeat the same moment from home position 0 point the controller just runs the servo to the same point by using the encoder data stored. A little more to it than that such as it can also tell how fast it is moving and direction by the encoder. So there is where you get the extreme accuracy, even 1/1000 of the motor rotation is counted and the harmonic drive may be 50 to 100:1 ratio.

You guys are just amazing. Every time I click on your videos, I just know I'm gonna learn something and that too in a simplest way possible. Thanks y'all. ❤

industrial robots very rarely using stepper motors. servos are much more common... also industrial machines NEVER use open loop system. they rely heavily on position encoders...

Best visualization I've seen yet. THANKS for this.

Thank you! This video explains everything so clearly. Looking forward to future videos!

theres a guy on youtube that makes music with these, but by the looks of it, smaller snd cheaper units. It’s awesome.

narrators voice was done using stepper motors. lol

Thank you for making such a great video! I understood the first motor though I didn't get how exactly the more common one works however I got some intuitive understanding of how they work.. thanks

Thanks Lesics team, you have an amazing art to teach typical things easily.

This is way better than going to class and sitting for an hour and 50 minutes listening to someone yap and draw crappy diagrams on a whiteboard.

I have learn from these chanal simple understanding ........................

Absolutely perfect animation and level of detail for an introductory video!

Best explanation of stepper motor I have seen so far. Thank you.

Great video. Whoever invented the stepper motor is a genius.

Thank you So Much ! Theory was not that intresting watching your video & studying know give's ma good idea how it word's . thank's again !

The clearest explanation for a stepper motor I’ve ever seen.

Шикарное объяснение. Спасибо!

very nice. the theory was great, regardless of others comments. easy to grasp for non engeneer/teckie types.

Great 🏆 You should make a video about Switched Reluctance Motor.

Very precise explanation , you guys are doing a great job.

Fantastic. Thank you very much! Folks, please support these people.

SO simple yet SO effective! Half stepping is crazy cool! Holy shit humans are amazing.

Spaceyman brought me here.

I misread the title and was like what is step motor? But I actually learned something so thank you.

I swear these animations teach us better than those teachers' hands.

To be accurate.. most robotic arms use servos not stepper.. nice explanation anyway.

make a video on servo motor. .

Excellently explained and thanks a million for NOT having any background RAP CRAP noise OR any other distracting sounds.

this's really helpful, u're making great videos, pls keep doing more. Thanks !

OK, well understood the step motor. But one more question: How do you rotate the 1.8 degree motor in the reverse direction?

What are you doing step motor?

This video was fantastic, and very well done. Thank you for the very clear explanation.

Thank you sir you are the one who given complete understanding of the hybrid stepper motor working principles

Aren't the hybrid's windings wrong? I mean, their magnetic fields seems to be backwards. If we follow the current direction through the coils, every instance where it says north it should be south and vice versa.

Excelent video. But i thought that all the robotic arms motor was a servo motor, stepper motors are too heavy compared to a servomotor with the same torque. Anyway, very nice explanation and keep going =)

Thank you guys, that was the best explanation of how a stepper motor work. Great job !

Such a beautiful and simple explanation.... Just loved it

But It seems the N S pole not obey right hand rule?

can someone explain to me why the step angle is 1/4 of the angular pitch h ????

Simple demonstration of a complicated operation. Great!!!!

extraordinary mental capability for whoever invented this motor . ..salute him

Are you sure that these robots used stepper motors? I thing they use servo motors.

Okay , I'm working with this robot arm and it started attacking me like it has gained a sentient state of existence .. It has made its intentions clear , What have I DONE??!! What have I created !!

excellent videos.each video covers all important concepts of a particular machine. animation and explanations are pretty good. kindly upload more videos on special electrical machines

Thanks for making this video, it helped me with my homework!

Imagine what would happen if this guy spoke to anyone in that voice face to face. SMACK!

Quite literally the worst voiceover ever. Why does every statement sound like an unsure question?

This video helped me a lot to understand and visualize the topic, thanks!

First time i learned how a stepper motor works. Watched tons of milling videos too. Engineering is so amazing. Humans are so smart!

4 years and it's still the best video.

Great video. I wish you had better audience and make more of them as your work is extremely usefull to understanding basics of operation for people that cannot get this knowledge easily enough or in reasonable time.

Thank you for all your effort and hardwork.❤

Amazing. Your videos just send big doses of adrinaline in my blood and make feel as though am the one who created all that technology. Thanks a million for the knowledge

Thanks for clearing my concepts

I invented this technology in 1974 while developing a blood analyzer. The technology was never patented since the company was a medical equipment developer and manufacturer. I taught the representatives of Superior Electric, the company that supplied the stepper motors, and the technology was published in training and repair manuals for the blood analyzer. I did encourage the company, my employer, to patent the micro stepping technology but the marketing department who was ask to review the commercial value said they could not find a market. Superior Electric was first at manufacturing micro stepping hardware based on my teaching them how it worked. I am presently working on an advanced driver technology that will improve efficiencies of operations and motor heating. Which I intend to patent. I am also working on motor improvements that will reduce the drive voltages both of which will open a new market to higher speed and higher power application of stepper motors. Larry Durkos
