A control circuit for a direct current motor which is to be operable from a source of alternating current power including a full wave controlled rectifier bridge circuit which supplies electrical power to the motor through appropriate circuit means selectively in one of two directions so as to control the direction of rotation of the motor. A braking circuit is also included which upon activation senses the direction of motor rotation and responds to this sensing by causing, in association with the switching means, the reversal of power application to the motor to bring the motor to a stop in a regenerative mode. |
