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: A rotor includes magnetic pole portions and first and second ferric core portions. The first and second ferric core portions are each located between magnetic pole portions in the circumferential direction of a rotor. A first gap is formed between the first or second ferric core portion and a magnetic pole portion at a first circumferential side. A second gap is formed between the first or second ferric core portion and the magnetic pole portion at a second circumferential side. The first gap has a smaller width than the second gap at the first ferric core portion. The first ferric core portion is inclined toward the first circumferential side. The first gap is larger than the second gap at the second ferric core portion. The second ferric core portion is inclined toward the second circumferential side.

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.

Abstract: A motor including a stator and a rotor. The stator includes teeth and windings. Each tooth has a distal portion defined by a radially inward side of the stator. The rotor, which is arranged inward in the radial direction from the stator, includes a rotor core, magnets, and salient poles. Each salient pole is separated by a void from the magnet that is adjacent in the circumferential direction. The distal portion of each tooth is longer than a radially outward side of each magnet.
