Magnetic levitation wind-driven generator with vertical shaft inner rotor

Abstract

The invention relates to a wind-driven generator, in particular to a magnetic levitation wind-driven generator with a vertical shaft inner rotor. The magnetic levitation wind-driven generator comprises three parts, namely a stator (1), a rotor (2) and a wind wheel device (3). A five-freedom degree magnetic levitation state is built by adopting the repelling force between an upper radial magnetized permanent magnet ring array (23) of the rotor and an upper radial magnetized permanent magnet ring array (12) of the stator, the repelling force between a lower radial magnetized permanent magnet ring array (25) of the rotor and a lower radial magnetized permanent magnet ring array (14) of the stator, and the repelling force between an axial magnetized permanent magnet (17) of the stator and an axial magnetized permanent magnet (28) of the rotor; dynamic adjustment on the radial position of the rotor (2) is carried out by adopting an upper radial adjusting coil (11) and a lower radial adjusting coil (15). According to the magnetic levitation wind-driven generator, the problem of difficulty in realizing stable magnetic levitation of the wind-driven generator with low power consumption is solved; the magnetic levitation wind-driven generator has the advantages of being low in start-up wind speed, reliable in operation and the like; a foundation is laid for light air start-up and breeze power generation.

Description

technical field [0001] The present invention relates to a wind power generator, in particular to a vertical shaft inner rotor magnetic levitation wind power generator. The wind turbine can be widely used in urban and rural road lighting, garden lighting, landscape lighting, advertising light boxes, traffic lights, road speed measurement power supply, unattended monitoring equipment and various power supply needs away from the power grid. Background technique [0002] The market potential of wind power generation is huge. China's wind energy reserves are large and widely distributed, laying a good foundation for the development of wind power generation in my country. Under the background of the country calling for vigorous development of clean energy, wind power generation has entered a period of rapid development. The wind power generators in the prior art can be classified into two categories: horizontal axis wind power generators and vertical axis wind power generators. ...

AI Technical Summary

Problems solved by technology

[0004] The wind power generators in the prior art have the following disadvantages: the cut-in wind speed is 3m / s, and cannot generate electricity when the wind speed is small or light wind; the system power consumption is high, making the conversion efficiency of wind power low; Collision and friction easily occur between rotor and stator
