ABSTRACT:
A rotating electric machine wherein sub slots serving as cooling fluid ducts in the axial direction are provided at the bottoms of the coil slots formed in the rotor, radial cooling fluid ducts are formed through the field coil of the rotor in the radial direction of the rotor and juxtaposed in the axial direction of the rotor, so as to communicate the sub slots with the air gap, and radial cooling fluid ducts are formed through the stator in the radial direction of the stator and juxtaposed in the axial direction of the rotor, corresponding in position to the radial cooling fluid ducts in the rotor, so as to communicate the inner periphery of the stator with the outer periphery of the stator.
