Abstract
A control device capable of suppressing electromagnetic force applied to a motor has a harmonic current calculation section and an operation section. The harmonic current calculation section calculates amplitude and phase of each of harmonic currents to be superimposed over a fundamental current which flows in phase windings of a stator of the motor based on conditions relating to load change of the motor. The operation section generates and transmits instruction signals to an inverter so that the calculated superimposed harmonic currents flow in the phase windings of the stator.
