Abstract
In a motor control device, a storage unit configured to store a relation between an advance angle of a drive waveform for driving a motor and a speed at which the motor rotates, for each amplitude of the drive waveform, a speed detection unit configured to detect a speed of the motor, a position detection unit configured to detect a position at which the motor has rotated; and a control unit configured to control an advance angle of the drive waveform and an amplitude of the drive waveform based on a cycle or timing in which the position at which the motor has rotated is detected by the position detection unit, wherein the control unit increase a speed of the motor by executing a first control pattern in which the advance angle of the drive waveform is increased if the speed of the motor detected by the speed detection unit is lower than a target speed, and the amplitude of the drive waveform is increased if a condition that an amount of increase in the speed of the motor resulting from an increase in the advance angle of the drive waveform is equal to or less than a predetermined amount of increase is satisfied are provided.
