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] With the rapid development of my country's national economy, the automobile industry has become one of the pillar industries of the national economy. It plays an indispensable role in industrial production, transportation and all aspects of human life. At present, the generator used with automobiles , there is a common phenomenon that 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 sp...
