Disk-type magnetic suspension outer rotor type vertical shaft wind-driven generator unit

Abstract

The invention discloses a disk-type magnetic suspension outer rotor type vertical shaft wind-driven generator unit which combines characteristics of Japanese coreless disk-type generators, a plurality of Chinese vertical shaft disk-type inner rotor generators and repulsion-type magnetic suspension vertical shaft disk-type generators and integrated and innovated on the basis of the characteristics. The disk-type magnetic suspension outer rotor type vertical shaft wind-driven generator unit is innovated in that the disk-type magnetic suspension outer rotor type vertical shaft wind-driven generator unit is a suction-type magnetic suspension vertical shaft wind-driven generator unit which is material-saving and low in cost compared with the repulsion type. No extra power supplies and controllers are needed to achieve self-adaptive balance, and accordingly the disk-type magnetic suspension outer rotor type vertical shaft wind-driven generator unit is high in cost performance and promising in market prospect.

Description

technical field [0001] The invention belongs to the technical field of synchronous generators, and specifically proposes a permanent disk type (axial magnetic field) generator structure with a quasi-magnetic levitation function. Background technique [0002] In the field of wind power generator technology, the generator is an electromechanical energy conversion device that is indispensable for converting mechanical energy into electrical energy. In order to obtain more energy from the wind, how to reduce the bearing friction force becomes the key to improve the performance of the wind turbine under the premise that the wind turbine is determined. It is hoped that the generator has lower mechanical noise, higher electromechanical efficiency, smaller mechanical resistance, longer operating life, and minimum starting resistance torque, and the magnetic levitation structure becomes the preferred solution. [0003] A wind turbine with a magnetic levitation function can obtain ma...

Problems solved by technology

However, after adding the usual full magnetic levitation device, the cost of the entire wind turbine will increase a lot, resulting in a decrease in the cost performance of the whole machine, which will increase the cost of power generation instead, which is not conducive to the popularization and application of wind power generators. Therefore, it is necessary to develop a new structure with high cost performance and low cost Disc type wind turbine with magnetic levitation function
