OK, PWM didn't register the first time I read it.( insert forehead slap smilie ) I read PWM controller, as a "brand name".
Pulse Width Modulation! Or, as it is sometimes called, Duty Cycle control, the length of the on time of the pulse determines the overall current. That would, at the frequencies you mention, provide safe higher voltage operation. The resistance of dust, dirt, or corrosion would be less of a factor. What drives the motor is average power (V-avg X I-avg).

We always learn far more from our own mistakes, than we will ever learn from another's advice.
The greatest place to live life, is on the sharp leading edge of a learning curve.
Lead me not into temptation.....I can find it myself!
