How does a Stepper Motor work? Full lecture

Stepper motor tutorial: Stepper motors are often used for positioning thanks to their fix step angle and also used within a servo drive. The stepper motor can be characterized as a DC and synchronous motor. How this stepper motor works and what else this motors offers, will be shown in this video:

Hi Friends - this is not really a new vide, but I want this video without a bug and spoken by a speaker I prefer.

Very helpful video, well explained. Thank you.

The teeth on the stator should have the same spacing as the teeth on the rotor. They don't in this animation. At for example 4:20 the leftmost tooth on bottom stator winding A is aligned with a tooth on the rotor, but the teeth to the right get more and more misaligned.

is there a common stepper motor that's in the hobby space that has feedback with incremental encoders?

Are the coils wound clockwise or counter clockwise? Why?

It reminds me of the old WW2 briefing videos for soldiers xD

Someone gave us subtitles in spanish - thank you

Hi, i wonder if you can help me with my cause. I have stepper motor and running with driver. The problem is, it make clicking sound like relay each time it stopped. I cannot feel any movement from the motor. Is it normal for the stepper motor behave like that?
