Abstract
A motor control device includes a motor device, a speed command section, and a load detecting section. The motor control device includes: a motor configured to drive a rotating body and output a speed notification signal having an oscillation frequency corresponding to a rotational speed of the rotating body; and a driver IC configured to control a rotational speed of the motor. The speed command section is provided outside the motor device and configured to output a speed command signal designating a rotational speed of the motor to the driver IC. The load detecting section is provided outside the motor device and configured to derive a phase difference between the speed command signal and the speed notification signal and detect a load on the motor based on the phase difference.
