摘　　要：在说明ANSYS有限元分析软件基本原理与具体应用的情况下,基于该软件对电路耦合分析以及静态电磁场分析的优势,对该有限元分析软件的计算流程进行了详细的阐述,并对九相同步发电机进行了静态电磁场的有限元分析,得到了该电机的磁力线分布图和基波气隙磁通密度波形图,并求出了空载电压为额定电压时的励磁电流。本文为下一步研究同步发电机的电磁场性能打下了一定的基础。On the condition of describing the basic principle of finite element analysis software ANSYS and its specific application, based on the software of circuit coupling analysis and the advantage of static electromagnetic field analysis, the calculation process of the finite element analysis software are described in detail. And the finite element analysis of the static electromagnetic field is carried out for the nine-phase synchronous generator. The distribution of magnetic field lines and fundamental air-gap magnetic flux density waveform diagram of the motor are obtained, and the excitation current of no-load voltage of the rated voltage are also calculated. This paper lays a foundation for studying the electromagnetic field performance of synchronous generator.
