Abstract
A motor control apparatus includes: a motor configured to drive a load; and a control unit configured to control the motor. The control unit is configured to, when activating the motor, determine whether a predetermined condition for determining that fluctuation in magnitude of the load occurs is satisfied, activate the motor in a first mode when the predetermined condition is satisfied, and activate the motor in a second mode when the predetermined condition is not satisfied, and the first mode is a mode in which an increase in rotation speed of the motor is gentler than an increase in rotation speed of the motor in the second mode.
