Assembly Process's Simulation of High-Field Permanent-Magnet Flux Source Based on Vector Magnetic Hysteresis Model

In this paper, the recently research results of assembly process's simulation of high-field permanent-magnetic flux source is presented. A 2D vector Jiles-Atherton magnetic hysteresis model is employed in magnetic field finite element analysis. Abnormal magnetization phenomena of permanent magnetic material during the assembly process are simulated and the distribution and account of abnormal magnetization points is obtained. It can be a significant guide for the manufacture of magic ring.
