Re: Running DC Motors in Series

Aaron,
The caps you are suggesting are available in electrolytic varieties. Those types of capacitors do not like having reverse polarity. The PWM output of either type of controller does not work well into a capacitive load. The controller is asked to charge the cap and move the motor at the same time.
