Abstract

The invention provides a radial and tangential permanent magnet composite magnetic circuit generator for vehicles, belonging to the technical field of vehicle motor appliances. The generator comprises a rotor, a stator, a front end cover, a rear end cover, an electronic stabilization controller; a tile magnetic steel provides a radial permanent magnetic field; a rectangular magnetic steel provides a tangential permanent magnetic field; the radial permanent magnetic field and the tangential permanent magnetic field share one same rotor iron core; and a magnetic field in an air gap of the generator is provided by the radial permanent magnetic field and the tangential permanent magnetic field together. The magnetic field is large in intensity; the generator is high in power intensity and the structure is compact; the generator is free from a carbon brush slip ring structure, low in fault rate, free from an electric exciting winding, little in electric energy consumption, and high in power generation efficiency; and direct current with stable output voltage is provided for electric devices of modern vehicles.

Description

technical field [0001] The invention provides a radial and tangential permanent magnet composite magnetic circuit generator for automobiles, which belongs to the technical field of automobile motors and electrical appliances. 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: 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...
