Design and Optimization of Double-layer and Salient-Pole Type Axial Flux Permanent Magnet Machine With PCD Stator
AFPM is a research focus recently,in this paper,a new type of salient pole Halbach permanent magnet array was applied to the motor,and its structure and advantages were described.A preliminary para-metric model was established with the help of 3D finite element software,and the simulation was further car-ried out by Workbench and Optislang,and the optimal design scheme was obtained by global multi-objective optimization through GA.Compared with the conventional Halbach structure of the same size,the optimized new permanent magnet array reduced the amount of permanent magnet,reduced the production cost of the motor,and improved the sine of the fundamental magnetic density amplitude and the air gap magnetic density waveform generated per unit of permanent magnet.In order to ensure the ideal air-gap magnetic field densi-ty,the cost of the motor was reduced by adding low-cost soft magnetic material,which provided a certain ref-erence for the design of axial flux permanent magnet motor.
