A motor control apparatus has an inverter circuit having a plurality of pairs of upper and lower arms provided so as to correspond to a number of phases, and switching elements provided on each of the upper arms and the lower arms of each phase that drive a motor on the basis of ON or OFF operations of the respective switching elements, a single current detector that detects a current of the motor flowing through the inverter circuit, and a duty calculator that calculates duties of PWM signals for turning the switching elements ON or OFF on the basis of a deviation between a current value of the current detected by the current detector and a target current value. |
