Here's a fun video about the AC induction motor. Complete with campy 60's banter.

(They're using a 2-phase motor, not a 3-phase like we usually see in EVs.)

Yeah, I think the fact that fundamentals were so important then, they spent more time on them.

These days there's a chip available for every low level operation you could ever want to do so explanation of the fundamentals like this are gone by the wayside.

It's not just sad, it's a genuine concern.

Here's another oldie-but-goodie. This one's on DC motors (and generators). It doesn't mention it by name, but the place where they rotate the commutator to get rid of sparking - that's timing advance.

One thing they get wrong - the positive side of electric current does not attract the negative magnetic pole and vice versa. The physics of why the wire moves is a lot more complicated.
