Abstract
In this paper, an integro-differential method for the modeling od permanent magnets in 3-D space using edge finite elements is presented. The value of the coercive magnetic force Hc is integrated over the entire permanent magnet surface area. This procedure results in direct computation of the equivalent source current Lpm, which is afterwards assigned to surface edges of the permanent magnet. The proposed method exhibits accurate results with less computation effort and an improved convergence rate of the iterative solver. Also, presented in this paper is a comparasion of the results for a simple test model obtained by the integro-differential method and those obtained by the Biot-Savart Law and the current-sheet method. A comparison between numerical results and for more complicated application model is also given.
