PWM motor controllers

And that seemed to work fine in this case.

Hello Altrez,

PWM motor controllers are buck converters and operate efficiently employing current multiplication through a freewheeling diode. Matt is incorrect. They do not waste 50% of the power at half voltage. Please don't believe me and look up buck converter or PWM DC motor controller.
