考虑硅钢片二维矢量磁特性的复数E&S模型
A Complex E&S Model Considering 2D Vector Magnetic Properties of Silicon Steel Sheet
摘要
Abstract
The accurate modeling of electromagnetic characteristic of electric steel sheet has a significant effect on the magnetic field analysis and loss computation for electrical equipment. In this paper, a complex E&S magnetic properties model describing the 2D vector magnetic property of silicon steel sheet under both alternating magnetic field and rotating magnetic field was proposed. Based on 2D magnetic property measurement data, the effective magnetic reluctivity coefficients in this model were calculated according to average magnetic energy density in one time period, and the effective magnetic hysteresis coefficients were calculated from magnetic hysteresis loss density. The finite element analysis (FEA) combined with proposed magnetic property model was derived. Taking the ring iron core computation model as example, the effectiveness of the complex E&S model was compared with traditional E&S model. It is shown that the proposed model not only can save computing time but also can guarantee the accuracy of the calculation when combined with FEA, and is more suitable for engineering applications.关键词
