Abstract

The provided five-phase Nd-Fe-B permanent-magnetic generator for vehicle comprises: the pole shoe, some permanent magnets with opposite polarity between near ones for N-S space array and every opposite to five poles on stator core, a rotor with iron core and shaft, and the stator composed by all of an iron core, a coiling, and a front / back cap. This invention has less wattless loss, compact structure for small room, and convenient to assemble for different vehicles.

Description

technical field [0001] The invention provides a five-phase NdFeB permanent magnet generator for vehicles, which belongs to the field of permanent magnet generators. Background technique [0002] The permanent magnet generators used with vehicles for a long time 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 base through the positioning bearing, and the ...
