Abstract

The permanent magnet generator in six phases includes rotor and stator. The rotor is composed of pole shoes, permanent magnets, rotor core and shaft. The stator is composed of stator core, armature winding, front end-cap, and back end-cap. Characters are that through pole shoes, permanent magnets are fixed on the rotor core by using non-magnet conducted screws. Adjacent permanent magnets are in opposite polarities so as to form interphase arrangement of N pole and S pole. Permanent magnets in rotor core are corresponding to six poles in stator core so as to constitute permanent magnet generator in six phases. Since possessing more number of phases, lower frequency, and less number of turns in winding of each phase as well as winding is in small synchronous reactance, the generator provides features of less loss of reactive power, compact structure, small space of use, and easy of use. The generator is applicable to automobiles for supplying dc power.

Description

technical field [0001] The invention provides a six-phase permanent magnet generator for automobiles, which belongs to the field of permanent magnet generators. Background technique [0002] For a long time, permanent magnet generators used in conjunction with automobiles generally have the problems of poor low-speed power generation effect and low output power, which cannot meet user requirements. For example, the invention patent announced on August 8, 2001 in the Chinese Patent Gazette: Stabilized Permanent Magnet Generator, application number: 00 1 12053.0, consists of a casing, a frame, a power shaft, a rotor, a permanent magnet steel, a stator, and a stator winding , 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 base through the positioning bearing, and ...
