<P>PROBLEM TO BE SOLVED: To provide an electromagnetic rotary electric machine that improves holding strength of rotor windings against centrifugal force. <P>SOLUTION: A stator 12 includes a plurality of stator windings 20u, 20v, and 20w wound around teeth 18. A rotor 14 includes: a rotor core 24; a plurality of rotor windings 28n and 28s wound around a plurality of main salient poles 26 of the rotor 14; and diodes, as magnetic property adjusting sections, that circumferentially vary magnetic properties developed in the main salient poles 26 by induced electromotive force generated in the rotor windings 28n and 28s. The rotor 14 has auxiliary salient poles 44 that project from respective circumferential side surfaces of the main salient poles 26. A rotor slot 46 is arranged between each adjacent pair of the main salient poles 26 in a circumferential direction of the rotor 14. Each circumferentially adjacent pair of the auxiliary salient poles 44 in each of the rotor slots 46 is joined to each other in each rotor slot 46. The rotor windings 28n and 28s are at least partially arranged on radially inner sides of the auxiliary salient poles 44. <P>COPYRIGHT: (C)2013,JPO&INPIT |
