Abstract
A DC motor control method and apparatus for reducing time required for deceleration without degrading positioning accuracy. In a device which drives a mechanism by using a DC motor as a power source, in deceleration of the DC motor, when the mechanism arrives at a predetermined position, a velocity command value to the motor, generated in accordance with a cubic function having a mild curve profile, is changed to a constant value, thus the velocity is discontinuously reduced.
