Abstract
The utility model provides a four-phase generator with Nd-Fe-B permanent magnets, comprising a rotor assembly and a stator assembly. The rotor assembly is composed of a pole shoe, Nd-Fe-B permanent magnets, a rotor iron core and a rotor shaft. The stator assembly is composed of a stator iron core, a coil, a front end cover and a back end cover. The four-phase generator with Nd-Fe-B permanent magnets is characterized in that a plurality of Nd-Fe-B permanent magnets pass through the pole shoe and are fixed on the rotor iron core through non-magnetic conducting screws. The contiguous Nd-Fe-B permanent magnets have opposite polarities, so as to form an interphase arrangement of N pole and S pole. Each Nd-Fe-B permanent magnet on the rotor iron core is corresponding to four poles on the stator iron core, so that the four-phase generator with Nd-Fe-B permanent magnets is formed. As the generator has multi-number phases, low frequency, less turn number of each phase winding and small synchronous reactance of armature winding, the utility model has the advantages of less reactive power loss, large effective output, compact structure, small space occupation and convenient installation and using. The four-phase generator with Nd-Fe-B permanent magnets is suitable for providing direct current power supply for the facilities of various automobiles using electric power.
