I spent the last few days experimenting with PWM speed control with DC motors and got me wondering: is there an optimum PWM rate? I know in terms of average power, there is normally no frequency preference with resistive devices, but I don't really expect this apply to reactive components like solenoids or motors. But mostly I am looking for a minimum rate to free up the most processor time possible.
So is there an optimum frequency? How can I determine it? :?
