I created this video for my Motors and Drives class at CPTC.
Sorry that the explanation isn't clear in some places, I was trying to get through it in one take without a script. Here are some points I could have explained better:
Motor Function:
Coil (A) wraps down to the bottom of the rotor and backs up. The eddy currents going down the stator spin in the opposite direction of the wire returning relative to the rotor. This is what creates (A) and (!A), which is why they're always opposite.
Feel free to post questions in the comments!
