Abstract

The invention provides a radial-tangential permanent magnet and electromagnetism mixed excitation generator, belonging to the technical field of an electrical appliance of a motor of an automobile. The excitation generator consists of rotors, a stator, a front end cover, a rear end cover and a rectifier, wherein the permanent magnet rotor and the brushless electrically-excited rotor are arranged on a shaft and commonly adopt one armature winding, a generated magnetic field is formed through combination in a parallel connection form in an air gap of the generator, and the size of the magnetic field formed by combining a permanent magnetic field and an electrically-excited magnetic field in the air gap of the generator is changed through regulating the size and the direction of the current passing the electrically-excited rotor, so as to ensure that the generator can output the direct current with stable voltage under the conditions of variable rotation speed and variable loads, thereby supplying electrical energy for electric equipment of the automobile.

Description

technical field [0001] The invention provides a radial and tangential permanent magnet and electromagnetic hybrid excitation generator, which belongs to the technical field of automobile motors and electrical appliances. Background technique [0002] The automobile industry is a symbol of modern industry and a leading industry in the development of the national economy. It plays an indispensable role in all aspects of industrial and agricultural production, transportation, and human production and life. At present, generators used in conjunction with automobiles are ubiquitous The output power is small and the power generation efficiency is low, which cannot meet the user's 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,...
