A motor control device (a motor driver) for controlling, by a duty control, a current supplied to a motor includes a driving controller, an off controller, and a voltage acquiring section (an A/D conversion processor, a sampling section). The driving controller performs on/off control of the current supplied to the motor with a first period. The off controller performs off control for the motor with a second period separately from the on/off control performed by the driving controller. The second period is longer than the first period. The voltage acquiring section acquires a voltage between terminals of the motor during a time period in which the off control is performed by the off controller.
