Abstract
Considering the performance requirements of interrupter device, the microactuator used in the interrupter device of micro electronic mechanical systems(MEMS) fuse safety system was taken as investigation object, and a micro type disc electromagnet was taken as drivers, and the planar structure built on the base plate based on the MEMS technology was adopted. The main parameter was estimated and optimized by the optimization theory. The simulation was carried out to calculate the force and heat of three kinds of electromagnet products. Experimental results show that driving force can achieve to the level of mN, and the generating heat can meet the requirement while the primary clearance is 3 mm, and the slaving voltage is 5 V. The novel electromagnet actuator of MEMS fuse’s safety device can satisfy the fuze requirements, including small volume, large force, long stroke, non contact and adapting complicated environment.
