Abstract: An electric rotating machine includes a power transmission mechanism and an armature. The power transmission mechanism is equipped with a first, a second, and a third rotor. The first rotor includes n soft-magnetic members. The second rotor includes k soft-magnetic members. Note that n and k are an integer more than one. The third rotor is made up of magnets whose number of pole pairs is m where m is an integer more than or equal to one. The armature faces the third rotor. The first, second, and third rotors are arranged so as to establish a magnetic coupling among them. The soft-magnetic members of the first and second rotors and the magnets of the third rotor meet a relation of 2m=|k±n|. This arrangement is capable of achieving the transmission of power regardless of electric energization of the armature.

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.
