ROTARY ELECTRIC MACHINE / DENSO CORP PROBLEM TO BE SOLVED: To provide a rotary electric machine capable of reducing a torque ripple without requiring higher performance control units.SOLUTION: Three-phase windings 55 and 56 are energized so that the phase difference θe1 between each pair is 30±60×n [deg] in the electrical angle. A tip portion 78 of a tooth 76 has a skew structure having a plurality of skew forming portions 781 and 782 divided in the axial direction so as to be shifted by an electrical angle of θe2 in the circumferential direction. θe1>θe2. Defining the radial distance between the teeth 76 and the circumscribed circle Cc of a rotor core 64 as a, and the radial distance between outermost magnets 86 and 87 located at the outermost side in the radial direction of a permanent magnet 65 and the circumscribed circle Cc as b, a/b<1.SELECTED DRAWING: Figure 6 |
