Research on Multi-physical Field Design of Spoke Permanent Magnet Synchronous Motor
The electromagnetic-mechanical-thermal multi-physical field finite element model of Spoke perma-nent magnet synchronous motor was established in this paper,and then the scheme design and performance analysis were completed.First,a two-dimensional electromagnetic model was established by considering the transverse effect with equivalent method,the integrated iron core of rotor structure was designed and opti-mized,and then the electromagnetic performance and the loss of rated condition were obtained by simula-tion.Second,based on the established three-dimensional mechanical strength analysis model of the rotor,the stress and deformation were calculated and simulated under enlarged load condition.Third,a thermal model was established by Fluent after the equivalent method of winding and insulation were investigated,and then the dynamic temperature rise of the motor at rated condition was simulated with the loss as the heat source,which was calculated in former electromagnetic model.Finally,a prototype was made and its elec-tromagnetic and thermal performance were tested.The multi physical field finite element models and design scheme were validated.
