In order to optimize the magnetic circuit structure design of 75kW tidal current energy permanent magnet generator,this paper selects the appropriate electromagnetic topology according to the technical requirements and boundary conditions,preliminarily determines the electromagnetic structure,and then uses the finite element simulation analysis software to calculate the electromagnetic parameters.Many problems such as the eddy current loss,the second air gap and tie rod circulation are analyzed.The results show that the finite element simulation analysis software is used to calculate the electromagnetic parameters intuitively and accurately.The simulation results of the second air gap and the tie rod circulation provide the basis for the design of the magnetic circuit structure.
