Abstract: In a control apparatus, a fundamental voltage generator generates, based on a target rotational speed, a fundamental voltage command for a fundamental voltage. A property storage stores a natural vibration property of a rotor when the rotor is rotating as a rotating vibration property. A rotating state detector detects a rotating position and a rotational speed of the rotor as a rotating state of the rotor. A harmonic voltage generator generates, based on the rotating state of the rotor and the rotating vibration property, a harmonic voltage command to be superimposed on the fundamental voltage command generated by the fundamental voltage generator.

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.

Abstract: In a control apparatus, a magnetic flux information acquiring unit acquires magnetic flux information of magnetic poles of a rotating electric machine. A fundamental setting unit sets a fundamental command value for supplying a fundamental current to a winding of the rotating electric machine. A harmonic setting unit sets, based on the magnetic flux information acquired by the magnetic flux information acquiring unit, a harmonic command value for supplying a reduction current to the winding. The reduction current is a harmonic current for reducing variation in a radial electromagnetic force acting on a rotor of the rotating electric machine. An operating unit operates, based on the fundamental command value set by the fundamental setting unit and the harmonic command value set by the harmonic setting unit, an electric power converter to supply the winding with a drive current that is obtained by superimposing the reduction current on the fundamental current.
