Abstract
Electromagnetic system (EMS) is the important part of electromagnetic relay (EMR). Considering the contradiction of efficiency and accuracy of solving EMS, a method integrating advantages of magnetic equivalent circuit (MEC) method and finite element method (FEM) was presented to quickly calculate the dynamic characteristics of EMR. The fast calculation of dynamic characteristics of EMR could be accomplished by this method, when dimension parameters of EMS varied. The accuracy of solutions using the proposed method was verified by comparing with the results of FEM. Moreover, adopting geometry dimensions as design variables, taking increasing the contacts' breaking velocity and decreasing closing velocity as goals, the EMS was optimized by genetic algorithm (GA), and the optimized results were finally given.
