Abstract

The invention provides an axial magnetic field permanent-magnet generator for an automobile, and belongs to the technical field of automobile motor electric appliances. The axial magnetic field permanent-magnet generator comprises power generation systems, permanent magnets, a rotor, a front end cover and a rear end cover, wherein the power generation systems and the permanent magnets are same in number and fixed on the same circumference inside the inner cavity of the rear end cover through screws at intervals. According to the invention, the rotor is in a ring flange structure without an electric excitation winding or the permanent magnets, so that simple structure and small rotational inertia are achieved; the excitation magnetic field is provided by the permanent magnets, so that less electric energy consumption is achieved because no electric excitation winding exists, and low failure rate is achieved because no carbon brush slip ring structure exists.

Description

technical field [0001] The invention provides an axial magnetic field permanent magnet generator for automobiles, 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 However, there are problems such as high failure rate and low output power, which cannot meet the requirements of users. For example, the invention patent announced in the Chinese Patent Gazette on January 10, 2007: hybrid excitation voltage stabilizer generator, application number: 200510044103.9, consists of a rotor, a stator, a front end cover, a rear end cover, and an electronic controller, and a permanent magnet is ins...
