摘要

为了明确SPM电机定子铁芯在1.3T以上高磁通密度条件下的铁损分布，采用了积分型动态E&S模型。在高达1.8T的高磁密度条件下，对磁芯材料的矢量磁特性进行了测量，建立了用于分析的磁特性数据库，并推导了积分型动态E&S模型的磁阻系数和磁滞系数。结果表明，积分型动态E&S建模具有较好的收敛性，具有一定的适用范围。指出了应用积分型动态E&S建模时遇到的一些问题。

Magnetic characteristic analysis of SPM motor by means of dynamic E&S modeling

To make clear iron loss distributions in a stator core of SPM motor under high flux density condition over 1.3T, the integral-type dynamic E&S modeling is employed. The magnetic property database for this analysis is newly prepared in the measurements of the vector magnetic properties of the core material under high flux density conditions up to 1.8T, and then the magnetic reluctivity and hysteresis coefficients of the integral-type dynamic E&S modeling are derived. The results show that there is an applicable region of the integral-type dynamic E&S modeling to obtain a good convergence. We also point out some problems encountered in applying integral-type dynamic E&S modeling.
