【Abstract】 To reduce startup wind speed of wind turbines,the structural design and mechanical properties of permanent magnetic bearings for 1 k W vertical wind turbines are studied from perspective of supporting technology. The permanent magnetic bearings are manufactured and assembled. The accuracy of theoretical analysis is verified by loading experiments,and the industrial application of the bearings is discussed. The results show that the bearings expand adaptive areas of wind fields,the rotational speed of permanent magnetic levitation wind turbines and generated energy is much higher than that of wind turbines supported by rolling bearings.更多还原
