Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is further described: compound excitation synchronous generator comprises rotor, stator, front end cover 11, rear end cover 3, electronic controller 4, permanent magnet rotor and electric excitation rotor are installed on rotating shaft 1, permanent magnet rotor Share the same armature winding 10 with the electric excitation rotor, and the magnetic potential generated is combined in parallel in the magnetic circuit;

[0013] The permanent magnet rotor is a tangential structure, which is composed of a pole piece rotor core 12, a magnetic isolation bushing 13, a non-magnetic slot wedge 14 and a permanent magnet material 15. The permanent magnet material 15 and the adjacent permanent magnet material 15. The same polarity faces are arranged in the slots of the pole shoe rotor core 12 sequentially, and fixed with non-magnetic slot wedges 14. The pole shoe rotor core 12 is fixed on the magnetic isolation bus...

Abstract

The invention provides a combined excited synchronous generator, belonging to automobile electric motor and appliance technical field, comprising rotor assembly, stator assembly, front end cover, rear end cover, and electronic controller, and characterized in that a rotating shaft is equipped with a tangential permanent magnet rotor and a claw pole electrically excited rotor which share an armature winding and whose generated magnetic potentials are connected in parallel and synthesized in magnetic circuit; as operating, by regulating current amplitude and direction of the claw pole electrically excited rotor, it can regulate the superposed magnetic field of the permanent magnetic field and the electrically excited magnetic filed, keeping output voltage stability on variable speed and variable speed operating conditions. And it has compact structure, safe and reliable to use.

Description

technical field [0001] The invention provides a composite excitation synchronous 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: 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, ant...
