Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings: the combined magnetic pole type compound excitation generator for automobiles composed of a rotor, a stator, a front end cover 11, a rear end cover 6 and an electronic voltage regulator 1, the radial permanent magnetic field and the salient pole electromagnetic field Sharing the same rotor core 13, the generated magnetic field is synthesized in series in the generator air gap;

[0013] The rotor is composed of tile magnetic steel 10, pole shoes 7, screws 9, rotor iron core 13, shaft 5, and electric excitation winding 14. The rotor pole is a combined magnetic pole structure, and each rotor pole has multiple pieces of tile magnetic steel 10. The polarity of the convex surface of each tile magnet 10 is the same, and is fixed on the outer circle of the rotor core 13 by screws 9 through the pole piece 7. The adjacent rotor pole convex surfaces on the rotor have opposite polari...

Abstract

The invention provides a combined magnetic-pole-type composite excitation power generation device for an automobile, and belongs to the technical field of automobile motor electric appliances. The combined magnetic-pole-type composite excitation power generation device for the automobile consists of a rotor, a stator, a front end cover, a rear end cover and an electronic voltage stabilizing controller; a power generator rotor adopts a combined-type magnetic pole structure, the starting resistance and operation noises of the power generator are reduced, also a radial permanent magnetic field and a salient pole electromagnetic field share the same rotor iron core, the generated magnetic field is combined in series in an air clearance of the power generator, the magnetic field is high in intensity, and the power density of the power generator is high; when in operation, through regulating the dimension and direction of the electrified current of a salient pole electric excitation rotor, the overlapped magnetic field of the permanent magnetic field and the electric excitation magnetic field can be regulated; and the output voltage of the power generator in wide rotation speed and wide load range is kept to be stable, and a direct-current power supply is provided for electric devices for modern automobiles.

Description

technical field [0001] The invention provides a combined magnetic pole type compound excitation power generation device for automobiles, which belongs to the technical field of automobile electrical appliances. Background technique [0002] The automobile industry is the symbol of modern industry and the leading industry in the development of the national economy. It plays an indispensable role in industrial and agricultural production, transportation, and all aspects of human production and life. At present, the generators used in conjunction with automobiles are ubiquitous. Due to the phenomenon of poor lighting effect at low speed, it cannot meet the requirements of users. For example, the invention patent announced in the Chinese Patent Gazette on August 8, 2001: stabilized permanent magnet generator, application number: 00112053.0, consists of a casing, a frame, a power shaft, a rotor, a permanent magnet, a stator, a stator winding, a stator It consists of seat, stator...
