| 摘 要： | 本文运用有限元法,研究凸极同步电机的电磁参数计算并进行分析.以5kVA模拟同步机为实例,求解电机内磁场分布,进而根据所求得的磁场分布,用谐波分析法求解电机空载电势,分别用能量法和磁链法求得电机的有关电抗参数,同时得出一系列曲线,直接由电磁场求解电机的有关参数和特性曲线,更符合实际情况.这种分析方法将有助于改变传统的近似的电机设计和分析的方法.

| Abstract: | The calculation of salient pole synchronous machine electromagnetic parameter by finite elements method is presented. This paper, taking a 5KVA simulate synchronous machine, first calculates the field distribution "within synchronous machine and its parameters. Then on the basis of the field distribution, the no-lood voltage is calculated by harmonic analysis. And characteristic curves are gained and parameters are calculated by energy method. It is showed that these synchronous machine paramenters and characteristic curves conform to the objective law very much. This method will help improve the classic method of synchronous machine design and analysis. |
