英文摘要：

A 30 kW motor was designed by using Ansoft sofiware,and the finite element analysis model of the motor was established.Then the electromagnetic characteristics and the starting performance of the motor were analyzed.The size of the permanent magnet what affected the motor starting capability was researched,and the motor with solid style＇s rotor was tested.The experimental results prove the accuracy of the finite element analysis.Analysis show that LSPMSM with solid style＇s rotor has high starting torque and overloading ability,widely used in the oil field.
