摘　　要：介绍了高速永磁电机设计的总体流程,并提出高速电机设计中的几个关键问题,分析了不同气隙长度和定子槽数对电机性能的影响。结果表明,在一定范围内,气隙越大,转子损耗及转矩脉动越小,定子槽数越多,转子总体损耗越小。The overall design process and key issues of high-speed permanent magnet motors were described. The effect of the different air gap length and stator slot number on the motor performance was analyzed. The results show that larger air gap length decreases the rotor torque ripple and rotor loss, and larger number of stator slot decreases the rotor loss.
