Abstract

The disclosed generator includes stator iron core, auxiliary winding, magnetic cover, and rotor core etc. Characters are that main winding and auxiliary winding are setup on the stator core; the magnetic cover and built in excitation winding is setup at two ends of the stator core respectively as well as permanent magnet of radial excitation and magnetizer are setup at the rotor. Advantages of the invention are: (1) only one stator core in brushless, compact, small size, lightweight, and high reliability; (2) permanent magnet as main excitation, auxiliary winding as electric excitation so as to raise excitation efficiency, and lower temperature rise; (3) making motor in permanent magnet regulate and adjust voltage easily by auxiliary electric excitation, good adaptability and good electromagnetic compatibility.

Description

technical field [0001] The invention relates to a permanent magnet voltage regulating brushless generator. Background technique [0002] As we all know, permanent magnet motors bring difficulties to voltage regulation and voltage stabilization. Now people have no good way to solve the problem of voltage stabilization and voltage regulation. Contents of the invention [0003] The purpose of the present invention is to provide a permanent magnet voltage regulation brushless generator to solve the problems of voltage stability and voltage regulation. [0004] The present invention is achieved in this way, it includes stator core, main winding, auxiliary winding, magnetically conductive cover, excitation winding, rotating shaft, rotor end magnetic conductor, rotor core, permanent magnet, and it is characterized in that the stator core is covered with There are main windings, auxiliary windings, magnetic permeable covers ...
