摘要：A motor control device (10) supplies a drive control signal to a drive circuit (20)that drives a motor (30) at a constant period using a motor drive signal based on the

drive control signal, and shuts off the motor drive signal when a count value counted by acounter (23) that reset the count value if a state of the motor (30) changes exceeds athreshold corresponding to a plurality of driving periods of the motor (30). The motorcontrol device (10) includes: a control unit (11) that controls a setting unit (14) to set arotational direction of the motor (30) to a first rotational direction and a secondrotational direction reverse to the first rotational direction at the constant periodalternately, when a drive mode of the motor (30) is a position holding mode to drive themotor (30) so as to hold a rotational position of the motor (30).
