The terminology around motors is... inconsistent. Induction motors are a specific kind of brushless motor with windings on both the stator and rotor, so named because it induces a current inside the rotor windings.

Reluctance motors don't use permanent magnets or rotor windings and don't have rotor currents. Universal motors (which until very recently were absolutely ubiquitous in appliances) are commutated rather than inductively coupled and also don't have motors. There are a half-dozen other types but they're mostly novelties or variations on a theme.



Oh, I know about reluctance motors. I was wondering what kind is as cheap as you mentioned in your previous comment.

Take a note, while SRMs are very cheap, some vendors would bundle a some kind of constant torque motor driver circuit at very little extra https://www.alibaba.com/product-detail/60v-72v-1200w-switche...


Universal or DC motors for <300 W, induction for anything above that.
