I have not verified this with a scope but believe the PWM is 60 or 120hz. The triacs are triggered by line frequency. If you have a scope or frequency counter on a VOM just put it across the motor terminals.

BTW coreless motors are what should work with TMCC/Legacy. Brushless require special drive circuitry to mimic a commutator.

I admit to confusing the two.
