英文摘要：

The conventional electromagnetic valve actuator employs solenoid structure and its coil produces a great quantity of heat. In order to achieve large output force, save energy and reduce the heating of coil, this paper presented a novel design of bi-stable linear actuator with permanent magnets （ PM）, in which the steady states can be hold by permanent magnets circuit and the state conversion is realized by energizing the coil with positive or reverse direction pulse. 3D finite element analysis（FEA） model was established. PM height and air-gap space between PM and armature were optimized based on the actuator＇s FEA model. The experimental and the simulation results of the prototype prove that the actuator and the 3D FEA method are effective and practicable.
