摘要
提出了一种考虑旋转磁化及谐波磁场、基于电磁场有限元分析及Bertotti铁耗计算模型的永磁同步电机铁耗计算方法,并以某永磁同步电机产品为研究对象分析了定子槽口宽度、气隙长度、偏心距及不同供电方式等因素对铁耗的影响。
Taking into account of rotational magnetization and harmonic magnetic fi eld, a calculation method of iron loss for permanent magnet synchronous motor(PMSM) was presented, which was based on fi nite element analysis and Bertotti iron loss calculation model. A real PMSM was studied as a subject to analyze the impact of stator slot width, air-gap length, eccentricity and power supply mode on iron loss.
