Small magnetic suspension horizontal shaft wind power generator

Abstract

The invention relates to a small magnetic suspension horizontal shaft wind power generator which comprises a rotating shaft, a stator and a rotor, wherein one end of the rotating shaft (2) is supported by adopting a rolling bearing (13), and the other end is supported by adopting a permanent magnet bearing and provided with a paddle; and the stator and the rotor are distributed between the permanent magnet bearing and the rolling bearing. A magnetic suspension support technology is applied to the traditional small wind power generator, and therefore, the invention has the advantages of small start resisting moment, simple structure, low cost, low-wind speed start, easy assembly, and the like.

Description

technical field [0001] The invention relates to a small wind power generator and magnetic suspension support technology, in particular to a magnetic suspension horizontal axis small wind power generator capable of developing and utilizing low wind speed resources in vast domestic areas. Background technique [0002] Small wind turbine equipment is low in cost, pollution-free, low in energy consumption, flexible in structure, easy to install, use, and maintain. Therefore, small wind turbines are especially suitable for solving problems in remote pastoral areas, mountainous areas, islands, and border posts where power lines cannot be erected. , Meteorological stations, relay stations, street lamps, lawn lamps, parks, villas, etc. electricity problems. However, the start-up resistance torque of traditional small wind turbines is large, the start-up wind speed is above 3.5m / s, and the power generation wind speed must reach 4.2m / s. According to the statistics and calculations of...

Problems solved by technology

However, the traditional small wind turbine has a large starting resistance torque, the starting wind speed is above 3.5m / s, and the generating wind speed must reach 4.2m / s

According to the statistics and calculations of the China Meteorological Administration, my country's wind energy-rich areas account for 8% of the country's area, wind energy-rich areas account for 18% of the country's area, and wind energy available areas account for 50% of the country's area, of which the wind speed in the wind energy available area is greater than 3m The annual accumulative hours per second is 2000-4000, traditional small wind turbines cannot effectively develop and utilize low wind speed resources in vast areas of China
