Abstract

This paper proposes an algorithm to analyze the magnetizing process of a new anisotropic bonded NdFeB permanent magnet (PM) which is magnetized by a capacitor discharge impulse magnetizing fixture. In the algorithm, the magnetic field analysis and the prediction of the residual magnetic flux density are achieved by using the transient finite element method (FEM) incorporating the scalar Jiles-Atherton (J-A) hysteresis model. The validity of the suggested method is demonstrated by applying to a 4-pole ring-type anisotropic bonded NdFeB PM and comparing the numerical results with the experiment ones.
