How does a Stepper Motor work?

Stepper motors are the one of the most widely used motor type due to its simplicity and position control capability. This video gives a step-by-step explanation of variable reluctance stepper motor and hybrid stepper motor with help of animation. It also explains the concept of half stepping.

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!

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

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.

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).

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

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

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

[SgtJoeSmith]

narrators voice was done using stepper motors. lol

[nrdbear]

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.

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

[dangerwolk]

I have learn from these chanal simple understanding

[joshthompson]

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

[CombraStudios]

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

[_Anlex]

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

[videogameclips]

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

[ratgreen]

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

[DineshYadav]

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

[meetan-]

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

[juans]

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