| 摘 要： | 三相电励磁双凸极电机定子极数与转子极数之间的约束关系制约着其在低速直驱场合的应用。针对该问题，本文提出了一种多转子极DSEG电机新结构，推导了多转子极DSEM的定子极数与转子极数之间可能的配合关系，给出了多转子极DSEM定子极宽与定子极距之比的取值，并在此基础上建立了有限元分析模型对24/16、12/16和6/16三种结构的空载特性进行计算。有限元仿真结果验证了本文所提多转子极DSEG电机结构的合理性，表明了多转子极DSEG电机在定位力矩、功率密度和效率方面具有一定的优势。本文工作丰富了DSEG电机结构和理论。

| Abstract: | The objective of this paper is to presents a series of novel doubly salient electromagnetic generator (DSEG) with multiple rotor poles for direct driven wind turbine. The 6k/4k-pole DSEGs are restricted in direct drive wind power situation for the constraint relations between stator pole numbers and rotor pole numbers. Recent work by the authors shows a series of DSEG which the rotor pole number is more than the stator pole number. 2-D finite element analysis software for DSEG was developed and the obtained results verify the rationality of new structures and show that the new structures have many attractive advantages with cogging torque, power density and the efficiency. |
