Abstract

The invention discloses a magnetically-assisted starter for vertical-axis wind turbines. The magnetically-assisted starter comprises a rotor and a stator; the rotor is arranged above the stator; the rotor is fixedly connected with a wind wheel; the stator is fixed; an air gap is reserved between the opposing outer faces of the stator and rotor; more than two magnetic suspension permanent magnets are evenly arranged on the periphery of the outer surface of the stator in the air gap; one N-pole or S-pole end of each magnetic suspension permanent magnet faces to the opposing outer face of the rotor at the same time; paired magnetic drive permanent magnets mutually acting with the magnetic suspension permanent magnets are evenly arranged on the periphery of the opposing outer face of the rotor in the air gap; one in each pair of magnetic drive permanent magnets is provided with an N-pole facing to the opposing outer face of the stator, and the other one is provided with an S-pole facing to the opposing outer face of the stator; magnetic poles, facing to the stator, of the magnetic drive permanent magnets are alternately arranged by facing to the stator. The magnetically-assisted starter has the advantages of simple structure, low cost, convenience of installation and the like.

Description

technical field

[0001] The invention belongs to the cross technical field of combining a vertical axis wind power generator and a magnetic drive machine, and relates to a magnetic drive device for auxiliary start of a vertical axis wind wheel with simple structure, convenient manufacture, low cost and easy installation and maintenance. Background technique

[0002] Wind energy is a clean and non-polluting green renewable energy, which has gradually become a new energy that is vigorously developed and utilized by countries all over the world. After years of "enclosure" in my country's "Three Norths" (Northeast, North China, and Northwest) regions, which are rich in wind energy resources, the development of wind power has become saturated. Both wind power operators and wind turbine manufacturing industries regard the utilization of low wind speed wind energy resources as one of the new key development directions.

[0003] The wind rotor structure of the vertical axis wind tur...
