接触器用交流电磁铁三维磁场分析和静特性优化

Analysis of 3D Magnetic Field and Optimization of Static Force Matching Characteristics for AC Actuator Used on Contactor

用ANSYS软件分析了接触器用双E型交流电磁铁三维工频磁场 ,根据交流电磁吸力平均值的直流等效原理 ,分两步计算了衔铁吸力 ,利用ANSYS优化设计方法对铁心厚度进行了优化。

D power-frequency electromagnetic field of an electromagnetic actuator used on AC contactor is analyzed by ANSYS software,and the average magnetic force of its armature is calculated.Optimization of iron core thickness is done by ANSYS optimization method.The matching between static magnetic force and counterforce is thoroughly discussed.
