Abstract

A motor control device according to the present disclosure is a motor control device configured to control voltage signals of a plurality of phases, the voltage signals being applied to an alternating-current motor, the motor control device including: a differential-value calculation unit configured to calculate the time differential value of a virtual line connecting peak values of each of phase voltage signals that are the voltage signals of the respective phases, the voltage signals being input to the alternating-current motor; a wavelength calculation unit configured to calculate the wavelength of each phase voltage signal input to the alternating-current motor from the time differential value; and a switching-signal generation unit configured to generate, based on the calculated wavelength, a signal that switches the phase of the alternating-current motor to which alternating-current voltage is applied.
