Abstract

A method for determining the magnetization of permanent magnets based on the known distribution of the magnetic field in the surrounding space is proposed, which enables taking into account the presence of soft magnetic ferromagnetic materials with known characteristics. The proposed approach is based on the use of the corresponding integral equation of magnetostatics. In the mathematical model of the magnetic field, we have considered the hysteresis effect of the frame material of an electrical device on the results of solving the inverse problem of permanent magnets magnetization identifying. The basic magnetization curve is calculated using the Langevin formula, and the hysteresis loop is determined using the selected range of the magnetic field strength values in accordance with the Giles–Atherton model. The results can also be used in solving the inverse problem for a system of ferromagnetic bodies and in test problems when using other methods. The optimization of coordinates of the induction measurement points has been carried out.

考虑磁滞的永磁体磁化控制和感应测量优化

摘要

提出了一种基于周围空间中的磁场的已知分布确定永磁体的磁化的方法，该方法使得能够考虑具有已知特性的软磁性铁磁材料的存在。所提出的方法是基于使用相应的静磁积分方程。在磁场的数学模型中，我们考虑了电气设备框架材料对解决永磁体磁化识别反问题的结果的磁滞效应。使用Langevin公式计算基本磁化曲线，并根据Giles-Atherton模型使用选定的磁场强度值范围确定磁滞回线。该结果还可以用于解决铁磁体系统的逆问题，以及在使用其他方法时的测试问题。已经对感应测量点的坐标进行了优化。
