Abstract

The invention discloses a field modulated permanent magnet wind driven generator, comprising a stator and a rotor which is arranged on the stator in a sleeving manner, wherein the part, along the radial direction, on the outer wall of the cylindrical stator extends outward to form a plurality of stator teeth, and the plurality of stator teeth are uniformly arranged around the center axis of the stator; dual-layer stator windings are wound on the stator teeth, and the number of the stator teeth is 16-20; the rotor comprises a plurality of fan-shaped rotor permanent magnets and a plurality of fan-shaped rotor iron cores, and the rotor permanent magnets and the rotor iron cores are alternately arranged and connected to form a complete annular rotor; the rotor permanent magnets have a magnetism concentrated structure, and are magnetized by a Halbach magnetizing mode; a magnetic barrier sleeves outside the rotor; and a magnetism regulating ring is arranged in the air gap between the inner wall of the rotor and the outer wall of the stator. The field modulated permanent magnet wind driven generator has a simple structure, rotates smoothly, and has stronger applicability for low-speed direct-driving application requirements.

Description

technical field [0001] The present invention relates to generators, in particular to field modulated permanent magnet wind generators. Background technique [0002] With the development of science and technology and the continuous improvement of people's quality of life, environmental problems have attracted more and more attention. Therefore, more clean energy is needed to replace traditional thermal power generation. And wind energy is welcomed by people because of its non-polluting, non-energy-consuming, and nature-derived advantages. Therefore, the technology of wind power generation is becoming more and more mature on the way forward. [0003] In the field of wind power generation: 1. The wind turbine driven by the traditional wind generator generally works at a low speed state. In order to form a high-speed power generation system, a mechanical speed-up gearbox needs to be added to the transmission chain. To increase the volume and weight of the power generation syst...
