• Line start
• Magnetic bridge
• Permanent magnetic
• Rare earth magnet
• Starting process
• Transient finite element method

The 2D transient FEM was used to analyze the starting process of the three phase rare-earth LS-PMSM. By verifying the simulation result with the experiment one, we get the conclusion that it is consistent with the experiment result very well. At the same time, by analyzing the situation of the magnetic bridge, we also get the result that the amplitude of EMF waves are changing with the situation of the magnetic poles and we can optimize the motor's structure at the same time.
