Electromagnetic-Thermal Coupling Analysis of Concentrated-Flux Permanent Magnet Synchronous Motor with Auxiliary Stator

Due to the structural characteristics of the inner and outer stator surrounding the rotor, the thermal circuit of the double stator motor is more complex than that of the single stator motor, and heat dissipation is more difficult. Based on a dual-stator ferrite permanent magnet motor (DS-FPMM) with...

Summary:Due to the structural characteristics of the inner and outer stator surrounding the rotor, the thermal circuit of the double stator motor is more complex than that of the single stator motor, and heat dissipation is more difficult. Based on a dual-stator ferrite permanent magnet motor (DS-FPMM) with an auxiliary inner stator, the temperature distribution and electromagnetic performance of the motor are compared and analyzed by direct coupling and electro-thermal two-way coupling methods. The results of finite element analysis show that the motor temperature obtained by two-way coupling is higher than that obtained by direct coupling, and the motor performance is reduced to a certain extent.
