A problem many have encountered in the RC electric plane world, where
controllers blow up at part throttle, not full (throttling being *done
by chopping the supply) .Its critically linked to the leakage inductance
of the motors: low inductance (the best motors) will have massive peak
currents at part throttle.
In the model train world it's expensive coreless motors that brick if
the PWM frequency is too low.

ah well we went high frequency many moons ago. For that very reason.
Well, so did model trains, to be fair.
