| Abstract: | Permanent magnet synchronous motor (PMSM) has been widely used in many fields due to its high power density, high torque density and high efficiency, especially in the field of new energy electric vehicles。Permanent magnet synchronous motor (PMSM) adopts different rotor topologies to obtain different motor performance。Based on Ansoft software, the finite element method is used to simulate the different rotor topologies of a new energy vehicle permanent magnet synchronous motor (PMSM)，the performance of motors with different rotor topologies is compared from the angle characteristics, reluctance torque characteristics, flux linkage characteristics, output torque external characteristics, output power external characteristics and motor performance parameters comparison table。The advantages and disadvantages of various topologies are analyzed, and the applicable occasions of different rotor topologies are pointed out. |
