Permanent-magnetic wind driven generator

Abstract

The invention discloses a permanent-magnetic wind driven generator, which comprises a base, a pair of base end covers connected to two ends of the base, a carbon brush and an electrical energy leading-out wire. The permanent-magnetic wind driven generator also comprises a wound rotor assembly, a permanent-magnetic rotor assembly and a pair of fan blades with opposite deflection angles; the permanent-magnetic rotor assembly is coaxially nested in the wound rotor assembly; the wound rotor assembly is coaxially nested in the base through the support of the pair of base end covers; the carbon brush is contacted with the wound rotor assembly and is fixedly connected to the side wall of the first base end cover; the electrical energy leading-out wire is connected with the carbon brush, and is led out through a corresponding open pore on the base; and the pair of fan blades with the opposite deflection angles are fixedly connected with the wound rotor assembly and the permanent-magnetic rotor assembly respectively. By adopting the permanent-magnetic wind driven generator, a wound rotor can rotate relative to a permanent-magnetic rotor at the same speed in the opposite direction, so the starting wind speed is reduced, and the utilization rate of wind energy is remarkably improved.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a permanent magnet wind power generator. Background technique [0002] With the increasing depletion of resources and the strengthening of environmental protection awareness, wind power, as the most competitive and promising renewable energy technology, has been highly valued worldwide, and wind power generator technology has shown rapid development. momentum. [0003] Traditional wind generators include DC generators, asynchronous and synchronous AC generators. No matter what kind of motor, they are composed of two main components: stator and rotor. The rotation of the rotor generates induced electromotive force in the winding in the changing magnetic field. Thereby converting the wind energy captured by the wind rotor into electrical energy. [0004] At present, the permanent magnet synchronous generator is widely used in wind power generation. The conventional permanent magnet synch...

Problems solved by technology

In order to reduce the resistance and loss in the intermediate process, direct drive technology is usually used now, but the use of direct drive requires an increase in the number of pole pairs of permanent magnets, which will cause unfavorable factors such as complicated motor processing and increased costs. Generators are required to have as low a starting wind speed as possible
