Abstract:
A DC motor control apparatus comprising:a rotation detector generating a pulse signal each time a DC motor rotates a predetermined angle; a servo command circuit providing a servo command signal when the rotation rate of said DC motor is judged, based on said pulse signal, to have decreased below a predetermined rate in response to a stop command given to said motor; a rotation direction indicating circuit providing, when said servo command signal is generated, a rotation direction indicating signal based on said pulse signal to indicate that said motor should be rotated in an opposite direction; a braking force indicating circuit generating and holding a braking force indicating signal based on an actual rotation rate at which said motor rotates after said servo command signal is generated; and a driver causing said motor to rotate in the direction indicated by said rotation direction indicating signal, while applying to said motor a braking force based on said braking force indicating signal.
