Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] The hybrid excitation generator and vacuum pump integrated device is composed of a vacuum pump, a front end cover 6, a rear end cover 2, a hybrid excitation rotor, and a stator 4. It is characterized in that the vacuum pump is fixed on the rear end cover 2 of the hybrid excitation generator through bolts, and the hybrid excitation rotor It consists of a salient pole electric excitation rotor and a built-in combined radial permanent magnet rotor;

[0014] The built-in combined radial permanent magnet rotor is composed of shaft 1, rectangular permanent magnet steel 5, tile permanent magnet steel 7, and rotor core 3. An even number of T-shaped salient poles are evenly distributed on the rotor core 3, and all T-shaped salient poles are evenly distributed. The outer sides of the transverse parts of the T-shaped salient poles are arcs and are on the same circle, the inner ...

Abstract

The invention provides a hybrid excitation generator and vacuum pump integrated device, and belongs to the technical field of automotive motors and electric appliances. The integrated device is composed of a vacuum pump, a front end cover, a rear end cover, a hybrid excitation rotor and a stator; a rectangular permanent magnet steel is installed in a rectangular groove of a T-shaped salient pole, a tile permanent magnet steel is installed in an arc groove of the T-shaped salient pole, and an electric excitation winding is wound on the T-shaped salient pole. The generated magnetic field directly faces air gaps, so that little flux leaks; the magnetic field in the air gaps of a generator is provided by the permanent magnet steels and the electric excitation winding together, so the strength of the magnetic field is high, the power density is high, electric energy can be provided for electric equipment of an automobile, and vacuum servo energy can also be provided for a brake system.

Description

technical field [0001] The invention provides an integrated device of a hybrid excitation generator and a vacuum pump, 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 phenomenon of unstable output voltage cannot meet the requirements of users. For example, the invention patent announced on August 8, 2001 in the Chinese Patent Gazette: Stabilized Permanent Magnet Generator, application number: 00 1 12053.0, consists of a casing, a frame, a power shaft, a rotor, a permanent magnet steel, a stator, and a stator winding , stator seat, stator sliding sleeve, balance spring, anti-rot...
