【摘要】：为从根本上解决传统直驱风机系统的机械摩擦问题以有效提高风能利用率,提出直驱风力发电机径向二自由度磁悬浮支承方案,即采用径向二自由度混合磁轴承和机械轴承共同支承直驱风力发电机,采用等效磁路法对该混合磁轴承进行数学建模,并利用有限元分析软件对其进行参数设计及机理分析。在此基础上,搭建直驱风力发电机径向二自由度磁悬浮支承系统的数控平台进行试验,试验结果证明该磁悬浮支承方案的正确性和合理性。
[Abstract]:In order to solve the problem of mechanical friction in traditional direct-drive fan system and improve the utilization ratio of wind energy, a radial two-degree-of-freedom maglev bearing scheme for direct-drive wind turbine is proposed. The hybrid magnetic bearings with radial two degrees of freedom and mechanical bearings are used to support the direct-drive wind turbine and the equivalent magnetic circuit method is used to model the hybrid magnetic bearings. On the basis of this, the numerical control platform of radial two-degree-of-freedom maglev support system of direct-drive wind turbine is built and tested. The experimental results show that the scheme is correct and reasonable.

【正文快照】： 0引言采用传统机械轴承支承的直驱风力发电机起动阻力和起动风速大(起动风速约3 m/s),使得风力发电的效率较低。磁悬浮风力发电机的诞生使得这个问题得以解决,将风力发电机中传统机械轴承替换成磁悬浮轴承,就构成了磁悬浮风力发电机。其优势在于:1)磁悬浮风力发电机的转子是靠
