考虑硅钢片各向异性的永磁同步电机三维电磁场计算

摘要

By using electromagnetic theory and finite element fundamentals, the calculating method of load performance for permanent magnet motor is present in this paper. By the FEM coupled field and circuit, the parameters including electric motive force, phase current, electromagnetic torque and core loss are calculated and analyzed.%本文利用ANSOFT数值计算软件的MAXWELL 3D模块建立了某永磁电机的有限元模型,模拟了取向硅钢片的各向异性特性,通过进行三维电磁场分析计算了电机的主要参数,提高了仿真计算的精度.
