Numerical analysis and experimental testing of modular bistable electromagnetic actuator in valve operation

A novel concept of modular bistable electromagnetic actuator in valve operation is numerically analysed, designed and experimentally tested. The actuator takes advantage of permanent magnets for assuring stable positions of the valve body and field coils for control of the valve operation. The paper presents the basic concept of the actuator together with its numerical investigation for the case of the first prototype and its experimental testing.
