A motor control apparatus is disclosed which comprises a speed control device for operating at a command speed a DC motor connected to a DC power supply, a dynamic braking device for braking the motor upon the issuance of a deceleration command, and a low-speed detector for generating a detection signal when the magnitude of the braking current of the motor is reduced below a set level. When the low-speed detector is energized, the speed control device is regulated thereby to run the motor at a predetermined low speed.
