Abstract: Based on operation mechanism of the electromagnetic brake  for vehicles,when the electromagnet being engaged,its work posture and wear were analyzed,an unsymmetrical magnetic circuit design method was presented by slotting in the inside flank of the electromagnet to attain the electromagnet‘s surface swearing evenly and preventing the revolving tendency.Ansoft/Maxwell 3D software was applied to get the optimized unsymmetrical structure and parameter.Wearing endurance comparison test of symmetrical and autonomous optimal design of unsymmetrical electromagnet showed the correctness of theoretical analysis and the superiority of the proposed method.
