中文摘要：

建立了垂直轴风力发电机转子系统装置，设计制作了同极型径向磁悬浮轴承和具有悬浮与刹车功能的轴向磁悬浮轴承，给出了该装置的主要设计过程和结构参数。测试了磁悬浮轴承控制参数的稳定区域，采用试验模态分析方法获取了系统的模态频率和模态阻尼，并验证了轴向磁悬浮轴承的刹车功能。结果表明，系统的第一阶临界转速远高于最大工作转速，系统在运行时不会出现共振；另外，轴向磁悬浮轴承可以满足刹车制动要求，有利于减小系统的体积和成本。

英文摘要：

The setup of vertical axis wind power generator rotor system is built. The homopolar radial active magnetic bearing and the axial active magnetic bearing with the function of suspension and brake synchronously are designed and manufactured. The main design process and configuration parameters are presented. Stability ranges of the control parameters of the active magnetic bearings are tested, the mode frequencies and modal damps of the system are obtained by experimental modal analy- sis, and the brake function of the axial active magnetic bearing is verified. The results show that the first critical speed of the system is far above the operating rotation speed, there is no resonance when the system is in motion. On the other hand, the axial active magnetic bearing can meet the brake demand and reduce the size and cost of the system.
