Monostable electromagnetic actuator for high-speed and fail-safe valve operation

摘要

AbstractA novel concept of monostable electromagnetic actuator with a fully magnetically moved plunger is proposed. The actuator takes advantage of permanent magnet for assuring stable position of the plunger and single solenoid coil for full control. The main advantage of the concept is high dynamic response and safety of operation. Consequently, major application of the novel actuator is a valve for controlling critical parts of hydraulic or pneumatic systems. Presented is the basic concept of the actuator together with its numerical investigation, sensitivity analysis, parametric study of prototype design, its manufacturing, fail-safe control and its experimental verification.]]>
