Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention is further described: permanent magnet and electromagnetic serial magnetic field hybrid excitation generator that are made up of rotor, stator, front end cover 11, rear end cover 6, electronic voltage stabilizing controller 1, radial permanent magnetic field and salient pole The electromagnetic field shares the same rotor core 13, and the generated magnetic field is synthesized in series in the air gap of the generator;

[0012] The rotor is composed of tile magnetic steel 10, pole shoes 7, screws 9, rotor core 13, shaft 5, and electric excitation winding 14. The tile magnetic steel 10 passes through the pole shoe 7 in such a way that the convex surface is N pole and S pole is arranged at intervals. The screw 9 is fixed on the outer circle of the rotor core 13, the rotor core 13 is press-fitted on the shaft 5, the coil of the electric excitation winding 14 is wound on the salient pole of the rotor core...

Abstract

The invention provides a hybrid excitation generator with permanent and electromagnetic series magnetic fields, and belongs to the technical field of automobile motor electric appliances. The hybrid excitation generator consists of a rotor, a stator, a front end cover, a back end cover and an electronic voltage regulation controller, wherein a radial permanent magnetic field and a salient pole electromagnetic field share the same rotor iron core; a generated magnetic field is formed through series connection in an air gap of the generator, the magnetic field intensity is high, and the power density of the generator is high; and during operation, the magnitude and the direction of the energization current of a salient pole electrical excitation rotor are adjusted to ensure that the magnetic field which is formed by superimposing the permanent magnetic field and an electrical excitation magnetic field is adjustable, the output voltage in a wide rotating speed and wide load range is kept stable, and a direct current power supply is provided for modern automobile electrical equipment.

Description

technical field [0001] The invention provides a permanent magnet and electromagnetic series magnetic field 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 low-speed lighting effect is poor, 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, stator sliding sleeve, balance...
