Abstract:
1. A motor control device that supplies a drive control signal to a drive circuit that drives a motor at a constant period using a motor drive signal based on the drive control signal used to generate torque on the motor, and shuts off the motor drive signal to the motor when a count value counted by a counter that counts the count value at a predetermined interval and resets the count value if a state of the motor changes exceeds a threshold corresponding to the count value for a plurality of driving periods of the motor, the motor control device comprising: a setting unit that sets a rotational direction of the motor driven under control at the constant period; a control unit that controls the setting unit to set the rotational direction of the motor to a first rotational direction and a second rotational direction reverse to the first rotational direction at the constant period alternately, when a drive mode of the motor is a position holding mode to drive the motor so as to hold a rotational position of the motor; and a generating unit that generates the drive control signal.
