摘要
永磁同步电动机(PMSM)的过载能力受到铁心饱和、电枢反应的制约,常规设计PMSM无法满足一些高过载应用场合的需求。分析PMSM过载能力的影响因素,研究定子裂比和气隙长度等结构参数对其影响方式,进而分析得出相关结构参数对于PMSM过载能力的影响规律。设计了1台额定功率1 kW的高过载能力PMSM,有限元仿真结果显示该电机可达到5.26倍过载能力。
The overload capability of permanent magnet synchronous motor (PMSM) was restricted by core saturation and armature reaction.Conventional design of PMSM could not meet the requirements of some high overload applications.The influencing factors of the overload capacity of PMSM were analyzed.The influences of structural parameters such as stator crack ratio, permanent magnet thickness and air gap length were studied.The influence rules of relevant structural parameters on the overload capacity of PMSM were analyzed.A high overload capacity PMSM with rated power of 1 kW was designed.The finite element simulation results showed that this motor could achieve 5.26 times overload capability.
