3次元VMSW法を用いた希土類永久磁石の残留磁化分布の評価

抄録

This paper presents results obtained from a numerical simulation of the magnetizing Nd-Fe-B magnets by using the three-dimensional Variable Magnetization and Stoner-Wohlfarth (VMSW) method combined with the finite element method (FEM) and external circuit equations. The initial magnetization curves of rare-earth permanent magnets measured with a magnetizer were used in the simulation. The calculated results were compared with the measured results to verify the numerical method of the simulating magnetizing process.
