Abstract
A hybrid excitation rotating electrical machine configured with a rotor having a shaft extended on at least one side in an axial direction, and first and second cores that are separated in the axial direction with a gap between the cores. First magnetic poles that are excited by a permanent magnet and second magnetic poles that are not excited by the permanent magnet are alternately arranged in a circumferential direction in each of the first and second cores. The first magnetic poles of the first core have a different polarity from that of the first magnetic poles of the second core, and the first magnetic poles of one of the first and second cores are placed so as to face the second magnetic poles of the other of the first and second cores in the axial direction with the gap between the magnetic poles.
