Hi Michael,
We talked about AC brushed motors a bit in the first video of module 8, unit 2. The universal motor that’s shown around 6:40 in that video is an AC brushed motor.
I recommend you review that video for more information, but essentially the biggest difference between AC brushed motors and DC brush motors is that the AC motors use windings instead of permanent magnets to produce the magnetic field in the stator. Other than that, they’re pretty similar to their DC counterparts.
