Abstract:
A rotary electric machine includes a stator and a rotor. The rotor includes a rotor core and a plurality of permanent magnets. The permanent magnets are disposed to be divided into two layers, the two layers being a layer on the outer peripheral side and a layer on the inner peripheral side of the rotor core, and the permanent magnets are disposed line-symmetrically with respect to a magnetic pole center of the rotor core and in a V-shape or a U-shape in each of the two layers. An angle that each of the permanent magnets disposed on the outer peripheral side makes with the magnetic pole center of the V-shape or the U-shape is larger than an angle that each of the permanent magnets disposed on the inner peripheral side makes with the magnetic pole center of the V-shape or the U-shape.
