Three-dimensional Modeling and Performance Analysis of Permanent Magnet Synchronous Motor

The three-dimensional model of rare earth permanent magnet synchronous motor is built based on SolidWorks software, the assembly and production explosion diagram are completed. Finally, shaft imported into Workbench interface ANSYS finite element analysis software for harmonic response modal analysis. results show that resonates under action 659.38hz exciting force, displacement value deformation largest in middle shaft, maximum stress appears near keyway end; first four natural frequencies modes from This research provides some reference improving performance motor.
