Abstract
A motor control circuit includes a switch circuit powered by a power supply to drive a motor to output a motion. A switch drive circuit sends a valid drive signal to the switch circuit to drive the motor to output the motion. A limit switch is associated with a position of the motor's motion output, enabling the motor to generate a feedback signal when the motor outputs the motion to the position in a direction. The switch drive circuit receives the feedback signal to cut off power from the power supply to the switch circuit, and the motor stops outputting motion. The motor control circuit feeds from the limit switch back to a controller. When the direction of the motion output by the motor is switched, the power from the power supply to the switch circuit is turned off using the feedback signal.
