| 摘 要： | 针对如何提高低速直驱双凸极发电机效率的问题,研究了一种多转子极电励磁双凸极发电机新结构,推导了该发电机定子极数与转子极数配合关系,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,在发电机转速、每相串联匝数、转子极数和主要尺寸相同的条件下对比分析了24/16、12/16和6/16极电励磁双凸极发电机的磁链、电动势、电感、定位力矩、效率和重量.分析结果表明本文所提多转子极DSEG发电机结构的合理性.

| Abstract: | The objective of this paper is to investigate the feasibility of the doubly salient electromagnetic generators(DSEGs) with multiple rotor poles for direct driven wind turbine and compare the performance between the new direct driven DSEG and the conventional(6k)/(4k)-pole DSEG.Stator pole and rotor pole combinations of the new generator are presented and the ratios of the stator pole width to the stator pole distance are deduced.2-D finite element simulation models for DSEG were also developed and verified ... |
