摘　　要：以双E型单相交流接触器电磁机构为研究对象,建立了含有分磁环并添加电压源激励方式的三维仿真模型。利用Maxwell瞬态磁场求解器,仿真分析了电磁机构的动态特性,并通过试验验证了仿真模型的准确性和可行性。在此基础上,侧重分析了分磁环的工作特性和对电磁机构动作特性的影响,以及分磁环参数对电磁吸力最小值、分磁环损耗的影响,为电磁机构的优化设计奠定理论基础。This paper takes the electromagnetic mechanism of double E-type single phase AC contactor as the research object,established a 3D simulation model composed of shading coil and voltage source excitation mode,and analyzed the dynamic characteristic of electromagnetic mechanism by Maxwell transient magnetic field solver. The accuracy and feasibility of the simulation model are verified by experiments. On this basis,it mainly analysed the shading coil's work characteristics and the effect on the operating characteristics,and the impact of the shading coil on electromagnetic force,magnetic loss. And it provides the theory basis for optimal design of electromagnetic mechanism.
