Abstract
A circuit allows an energy efficient DC design to drop in to an AC application and interface directly with the AC signals in a cost effective manner. The circuit is implemented without any use of mechanically switched contacts. All switching of current is done through solid state devices. Positional feedback and speed of the motor is provided through an optically encoded output gear eliminating the need for mechanical position switches to determine motor rotational position.
