硅钢叠片在宽频三轴正交激磁条件下的磁特性模拟方法研究
An Electromagnetism Simulation Methodology of Laminated Silicon Steel by Three Axes Orthogonal and Wide Frequency Excitation
摘要
Abstract
Laminated silicon steel can not be simulated accurately when the working frequency is higher than 50Hz. In order to solve this problem, magnetic properties of the laminated silicon steel were measured and modeled at broad frequency range (20Hz~1kHz). Firstly, a linear eddy current field analytical model was built for effectively predicting broad frequency range magnetic properties of the laminated silicon steel at low magnetic field. Secondly, a transient electromagnetic finite element method considering the eddy current effect in multi-domain and nonlinearity was proposed for 2-D magnetic modeling of silicon steel at high magnetic field. This method can separate the laminated magnetic core into multi-domain with eddy effect and compute its magnetization curve at broad frequency. At last, by using a three axes orthogonal magnetic tester, comprehensive magnetic properties of the laminated silicon steel were measured. By comparing the measured and simulated results, the validity of the proposed method can be verified.关键词
