Abstract
A rotary electric machine includes a rotor, and a stator facing the rotor with a predetermined gap interposed between the rotor and stator. The stator has a stator core formed in a substantially circular annular shape and provided with an armature slot and a field slot alternately arranged in a circumferential direction, an armature winding housed in the armature slot, and a field winding and a first field magnet housed in the field slot. The armature winding generates a rotating magnetic field to rotate the rotor by being supplied with an alternating current armature current. The field winding generates a field flux by being supplied with a direct current field current. The first field magnet changes a magnetic force by the field flux.
