Ummmm - if it's an induction motor, which you would be able to see by the plate on the motor showing an 'rpm',
you could destroy the controller and possibly the motor. Induction motors are mains synchronous and don't like
'dropping out' of that with overload or low voltage.


Is that a definitive method of identifying such a motor, then? A fixed
RPM shown on the plate?

No commutator.

And a capacitor starter.
brushed motors are in general NOT induction motors.
