Abstract

A rotor of a rotating electric machine includes a field core having a cylindrical boss portion, and a plurality of claw-shaped magnetic pole portions that are arranged on the outer side of the boss portion and form poles of alternately different polarities in the circumferential direction, a field winding that is wound around the outer periphery of the boss portion and generates a magnetomotive force by energization, a permanent magnet disposed between the circumferentially adjacent claw-shaped magnetic pole portions so as to have its easy axis of magnetization oriented in the circumferential direction and have its polarity coincide with the polarity of the claw-shaped magnetic pole portions which alternately appears by excitation, and a magnetic flux short circuit member having a short circuit portion that magnetically connects the claw-shaped magnetic pole portions circumferentially arranged to have different polarities.
