Nonlinear Numerical Calculation for Static Permanent Magnetic Circuit

描述了一种涉及具有非线性特征，由永磁体、软磁体材料构成的磁路的计算方法，包括材料处理模型及磁场计算．应用此方法分析了实用磁性器件的磁场，其计算结果与电磁等值法计算结果十分吻合．且此方法可以解决电磁等值法难以解决的复杂永磁磁路结构的优化设计问题．

This paper presents a new computing method for the calculation of magnetic circuits consisting of several different magnetic materials including those with hysteresis. The calculated results are in agreement with those by other methods. The optimum design of complicated permanent magnetic circuits can be achieved by using this method.
