DIRECT-DRIVE PERMANENT MAGNET SYNCHRONOUS SMALL WIND GENERATOR

摘要

A direct-drive permanent magnet synchronous small wind generator includes: a housing(1), a shaft(2) mounted in the housing(1) via bearings, the generator mounted with stators(7,8) and rotors(3,4) which have small number of slots and poles, each pole of the rotor (3,4) equipped correspondingly with a permanent magnet(5). The wind power generation system also includes an electric power storage device, a DC power supply adjusting control unit and a controller. The generator can keep the wind power generation system stable with the method of power adjustment and the energy compensation, and improve the efficiency of the power generation system.
