英文摘要：

Based on the distribution parameter model of nonlinear permanent magnet （NPM） , the analytical model of NPM polarized relay was built. The subsection divided interface of NPM was analyzed and the leakage magnetic permeability between armature and yoke was calculated. The electromagnetic force was calculated under different rotation angle. The results were eompared with that of the finite element method, which verifies the correctness and effectiveness of thte model.
