Abstract:

With the advantage of small volume, low power consumption, quickly switch, and high stability, the micro-electro-mechanical relay may bridge the performance and economic gaps between conventional electromagnetic relay and solid state relay. Analysis of three-dimensional magnetic field is the foundation work for optimum design of electromagnetic system. The magnetic distribution character of micro-electro-mechanical relay was analyzed by applying Biot-Savart law and integral equation method (IEM). The results of IEM and FEM show the method which used in analyzing three-dimensional stationary magnetic field for Micro-electro-mechanical relay is feasible. The revised schemes were designed basing on the original model features, and central planer coil structure was preferable by analyzing electromagnetic attraction force of movable contact. The optimum design was realized associated with the relationship among coil turns, exciting current and electromagnetic attraction force. The conclusions are valuable in theory and practice to design Micro-electro-mechanical relay.
