Abstract
A motor control apparatus drives an inverter which supplies and receives electric power with respect to a motor by pulse width modulation. The motor control apparatus sets a frequency of a carrier such that a frequency of a sideband wave component of the carrier which is used for the pulse width modulation and a frequency of a predetermined rotation order of the motor become different from each other.
