Abstract

Belonging to technical area of electrical motor and equipment of automobile, the mixed excitated voltage stabilized generator includes assembly of rotor, assembly of stator, front end cover, back end cover, and electronic controller. Characters are that tangential type rotor in permanent magnet and salient pole type electricity excitated rotor are installed on shaft. The said tangential type rotor and electricity excitated rotor share one armature winding. Magnetic potentials generated by them are synthesized in parallel in magnetic circuit. In operation, adjusting magnitude and direction of current in salient pole type electricity excitated rotor can adjust magnetic field of superposed magnetic field of permanent magnetism and electricity excitated magnetic field so as to guarantee stable outputted voltage when in state of variational rotation speed and variational load. Features of the generator are: compact structure, safety and reliable.

Description

technical field [0001] The invention provides a hybrid excitation voltage stabilized 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, and the output power is small, 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: 001 12053.0, consists of a casing, a frame, a power shaft, a rotor, a permanent magnet steel, a stator, a stator winding, Composed of stator seat, stator sliding sleeve, balance s...
