Design of the Line-Start Permanent Magnet Synchronous Motor Base on Induction Motor

A line-start permanent magnet synchronous motor(LSPMSM) developed by utilizing the stator of the three-phase induction motor and redesigning the rotor was presented.The finite element analysis(FEA) software was used to assess the performance of the amended LSPMSM by two-dimensional model.The simulation results indicate that the redesigned motor has good starting performance and significant improvement in power factor and efficiency.The energy-saving purposes was achieved.
