摘要： A permanent-magnetic type rotary electric machine includes a stator having teeth that are arranged in the peripheral direction thereof and around which armature windings of plural phases are wound, and a rotor having plural permanent magnets arranged so that the poles of the permanent magnets are alternately different in the peripheral direction thereof, higher harmonic waves being contained in a no-load induced voltage waveform. A (6p−1)-th higher harmonic wave and a (6p−1)-th higher harmonic wave (p represents a positive integer) when an electrical angle of 360° is set as a fundamental wave in the no-load induced voltage waveform are made substantially coincident with each other in amplitude and phase.
