To realize a high-torque and vibration-reduced low-cost rotary electric machine with a composite hybride type rotor.
The hybrid type permanent magnet rotary electric machine includes a two-phase and eight-main pole rotor including six inductive teeth on each end specified by having irregulator pitches. Two sets of a unit rotor each having a plurality of teeth rotatably mounted through air gap at a regular pitch, which sandwich two axially magnetized permanent magnets displaced by half pitch of teeth pitch each other, and having two magnetic circuits which are separated by providing the vicinity with the same polarity, are installed on the common rotating shaft. Permeance vectors in any one main one on fourth higher harmonic plane of the inductor are made into 12 vectors in total to cancel the fourth higher harmonics.
