Abstract
A six-wire three-phase motor that can realize both of increasing an output and reducing a torque ripple is provided. A six-wire three-phase motor is a six-wire three-phase motor including: a stator including a winding wire wound independently between phases; and a rotor including a plurality of magnets in a circumferential direction, wherein the stator or the rotor is configured in such a manner that a third harmonic current component in a motor current of when an overmodulation voltage based on a PWM signal is applied becomes higher than a third harmonic current component in a motor current of when a sinusoidal modulation voltage based on the PWM signal is applied.
