Problems solved by technology

[0002] Magnetic levitation bearings are applied to vertical axis wind turbines, which reduce or basically eliminate the radial friction force generated by ball bearings for the drive shaft and the axial friction force generated by heavy wind wheels and drive shafts, but the existing magnetic levitation vertical axis In wind power generators, the magnetic suspension bearings bearing axial force are troublesome to install, and the structure is complex and cumbersome. The Chinese invention patent, patent number 200610122794.4 "Vertical Full Magnetic Suspension Wind Power Generator" discloses the magnetic suspension bearing technology bearing axial force: generator The rotor is installed on the drive shaft, and the drive shaft is vertically installed on the magnetic levitation loading platform composed of the casing, suspension block, permanent magnet and adjustment block. While eliminating the frictional force generated by the axial force, there are problems such as troublesome installation of magnetic suspension bearings, complex structure and cumbersome problems

Abstract

The invention relates to a wind power generator of a vertical shaft with gravity and friction reduced by magnetic suspension, which comprises a wind wheel, a generator with a stator, a rotor and a generator shaft, wherein, the permanent stator magnet and the permanent rotor magnet of a magnetic suspension bearing are respectively fixed on the stator and the rotor and arranged top down with the permanent stator magnet under the permanent rotor magnet and the two opposite surfaces have the same polarity. The permanent stator magnet and the permanent rotor magnet of the magnetic suspension bearing are arranged inside the generator with compact structure. The wind power generator has simple integral structure and convenient site installation. The clearance of the upwards running and the downwards running of the generator shaft is less than that of the two opposite surfaces of the permanent stator magnet and the permanent rotor magnet, thus avoiding the contact of the permanent stator magnet and the permanent rotor magnet and protecting the permanent stator magnet and the permanent rotor magnet automatically. After the disappearance of special external force, the generator shaft resetsautomatically.
