Hi Art,

The question of low frequency PWM driving motors has come up before.
malc-c was trying to use it on a model train.

There was lot's of whining coming from the motor.
Didn't sound good at all.

I'm more of a software guy, so I really don't have much to offer on the hardware side.
But it seems that motors want a much higher frequency than Multi_SPWM can deliver.
