Abstract
A motor control device includes an energization pattern output portion and an inverter circuit. The energization pattern output portion cyclically outputs a plurality of energization patterns. The inverter circuit selectively connects respective coils provided in a motor to a rectifier circuit according to the output energization pattern. The energization pattern output portion delays the output timing of the energization pattern according to a rotation speed of the motor.
