ABSTRACT:
The electric rotating machine includes a rotor around which a field coil is wound, and a stator including a stator core around which an armature winding is wound. The armature winding includes a first three-phase winding whose phase coils are delta-connected to form a delta winding, and a second three-phase winding whose phase coils are connected to corresponding nodes of the delta winding to form a star winding. The delta winding and the star winding are wound around the stator core such that the phase coils of the delta winding and the phase coils of the star winding share the same slots of the stator core.
