Abstract: 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.
