Hmm, thanks for posting this. I'm using Compumotor OEM650 drivers on
some 42 frame motors. I'm running 40 volts at 7 amps. Only problem I've
had so far was one drive shut down due to heat. The heatsinks weren't
enough in ambient air (and were getting pretty hot) but a cheapo fan
cured that. I'm about to up voltage to 50, and hoping to land parts for
a 70 volt supply, so I'll be curious to see what's up with this, and
will go over my manual again.
