为研制系列永磁交流接触器，设计了一种新型永磁驱动器及其控制电路。采用基于参数网格划分的有限元方法，计算了不同位置电枢处的磁场和电磁力。对充放电过程进行了模拟和实验测量。模拟结果与实验结果吻合较好。
A new permanent magnet actuator and its control circuit are designed to develop a series of permanent magnet AC contactor in this paper. The magnetic fields and the electromagnetic forces on the armature at different armature positions are computed by the finite element method based on a parametric mesh generation. The charging and discharging procedures are simulated and experimentally measured. The simulation and experimental results are in good agreement.
