定子槽数和气隙长度对高速永磁无刷电动机性能的影响

摘要

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 lar-ger air gap length decreases the rotor torque ripple and rotor loss,and larger number of stator slot decreases the rotor loss.%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.
