摘要
提出了一种分析永磁电机退磁现象的新方法。例如，电动势(EMF)结果的实验测量已被用于计算磁铁在其不同区域的剩余感应(Br)。采用麦克斯韦方程组和梯度算法求解该反问题。本研究是对已有工作的延续[J]。Farooq et al.， 2006]，其中退磁建模分析被视为一个直接问题
An Inverse Problem Methodology to Analyze Demagnetization Phenomenon in Permanent Magnet Machines
The paper presents a novel approach of analyzing demagnetization phenomenon in permanent magnet (PM) machines. Experimental measurements of electromotive force (EMF) results for example, have been used to calculate the magnet's remanent induction (Br) in its different regions. Resolution by Maxwell's equations and gradient based algorithm is applied to solve this inverse problem. The research is a continuation of the work presented [J. Farooq et al., 2006], where demagnetization modeling analysis is taken as a direct problem
