| Abstract: | The double E-type- electromagnet to optimize the eleotromagnetism of AC contactor was in-vestigated. Design optimization in used to calculate the coil current. The magnetic field distribution of eleetromag-netism system was simulated and the characteristics of static attractive force were calculated using the 3-D finite ele-ment method. The numerical and experimental results are in good agreement. Based on these results, the influence of structure parameters on static characteristics was studied by means of virtual prototype technology. The optimal se-lection of geometry of magnet was proposed. |
