Rotating electric machine
Abstract:
A rotating electric machine includes a stator and a rotor. The stator includes a stator core and an armature coil wound on the stator core. The rotor is arranged radially inside the stator to radially face the stator. The rotor includes: a field core having a plurality of magnetic pole portions for respectively forming a plurality of magnetic poles the polarities of which are alternately different in a circumferential direction; a field coil wound on the field core; and a tubular short-circuiting member that is arranged radially outside the magnetic pole portions to cover radially outer surfaces of the magnetic pole portions and magnetically connects each circumferentially-adjacent pair of the magnetic pole portions. The short-circuiting member is provided within an axial range between two axial ends of the stator core.
