Abstract
The present invention provides a six-phase permanent magnet generator for automobiles, which comprises a rotor which is composed of pole shoes, permanent magnets, a rotor core and a rotating shaft, and a stator which is composed of a stator core, an armature winding, a front end cover and a rear end cover. The present invention is characterized in that through the pole shoes, a plurality of blocks of permanent magnets are fixed on the rotor core by non-magnetism conducting bolts; the polarities of the adjacent permanent magnets are opposite to form an N pole and S pole interval arrangement; each block of permanent magnet on the rotor core corresponds to six pole phases on the stator core to form the six-phase permanent magnet generator. With multiple generator phase number, low frequency, little turn number of each phase winding and small synchronous reactance of the armature winding, so the present invention has the advantages of little reactive power loss, large effective output, compact structure, little space occupation, and convenient use and installation, and provides DC power supplies for power utilization facilities of various automobiles.
