Problems solved by technology

The typical structure of the horizontal maglev wind turbine can refer to the Chinese invention patent "Magnetic Drive Magnetic Levitation Permanent Magnet Generator System" (application number: 99118905.1, publication number: CN1291819A) applied by Zhao Ke. The magnetic levitation bearing replaces the traditional ball bearing to form a magnetic levitation permanent magnet generator. Since the radial magnetic levitation bearing made of permanent magnetic material is affected by the weight of the generator rotor and the rotating shaft itself, it is easy to cause eccentric rotation and irregular vibration. Difficult to eliminate

Embodiment

[0030] Embodiment: Full Magnetic Levitation Wind Power Generator

[0031] The blades 4 of the wind generator are made of high-strength and lightweight materials (such as fiber reinforced plastics, carbon fiber composite materials, etc.). The drive shaft 2 and the permanent magnet generator 3, including the stator 31, the rotor 32, and the casing 33, are manufactured using conventional techniques and materials for generator manufacturing.

[0032] The magnetic levitation loading platform 1 is made of metal materials, the shell 11, the levitation block 12, and the magnetic pole spacing adjustment block 14 are respectively processed, and a hole 15 is opened at the bottom of the shell 11. The permanent magnet 13 is made of NdFeB permanent magnet material, and the permanent magnet 13 is respectively embedded on the suspension block 12 and the casing 11, so that the magnetic poles of the permanent magnet 13 embedded on the suspension block 12 and the corresponding permanent magnet e...

Abstract

A vertical full-magnetic suspension wind-driven generator consists of a magnetic-suspension loading platform, a driving shaft, a generator, blades and a radial magnetic-suspension bearing. The magnetic-suspension loading platform is used for carrying the dead weight of the generator rotor, the driving shaft and the blades. The radial magnetic-suspension bearing is used, so the whole rotating part of the wind-driven magneto generator realize the magnetic suspension completely.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a full magnetic levitation wind power generator. Background technique [0002] Wind power generation is one of the clean energy sources that are relatively easy to obtain, and many types of wind power generators based on maglev technology have been disclosed in the prior art. The maglev wind generators in the prior art can be divided into two types, one is horizontal, and the other is vertical. The typical structure of the horizontal maglev wind turbine can refer to the Chinese invention patent "Magnetic Drive Magnetic Levitation Permanent Magnet Generator System" (application number: 99118905.1, publication number: CN1291819A) applied by Zhao Ke. The magnetic levitation bearing replaces the traditional ball bearing to form a magnetic levitation permanent magnet generator. Since the radial magnetic levitation bearing made of permanent magnetic material is affected by the weight of the g...
