Abstract

The generator comprises rotor assembly composed of pole shoe, Nd-Fe-B permanent magnet, rotor iron core and rotor shaft, and stator assembly composed of stator iron core, coil, front-end cover and back-end cover. Characters are that Nd-Fe-B permanent magnets through pole shoes are fixed on the rotor iron core by non-magnetic conductive screw. Polarities of adjacent Nd-Fe-B permanent magnets are in opposition so as to form alternant arrangement between N pole and S pole. Each Nd-Fe-B permanent magnet in rotor corresponding to four poles in stator iron core so as to constitute Nd-Fe-B permanent magnet generator in four phases. Advantages are: low frequency, less number of turns in coil in each phase, small imaginary wastage, large effective output, small space etc. suitable to supplying DC power source.

Description

technical field [0001] The invention provides a four-phase permanent magnet generator for a hybrid electric vehicle, which belongs to the field of permanent magnet generators. Background technique [0002] For a long time, the permanent magnet generators used in conjunction with hybrid electric vehicles generally have the problems of poor low-speed power generation effect and low output power, which cannot meet the requirements of users. For example, the invention patent announced on August 8, 2001 in the Chinese Patent Gazette: Stabilized Permanent Magnet Generator, application number: 00112053.0, consists of a casing, a frame, a power shaft, a rotor, a permanent magnet steel, a stator, a stator winding, and a stator seat, stator sliding sleeve, balance spring, anti-rotation connecting screw, sliding block, adjusting shaft, positioning bearing, adjusting shaft driving mechanism and automatic feedback control circuit, etc. The power rotating shaft is fixed on the machine bas...
