Dynamic Displacement Response Characteristics of a Solenoid Actuator for Electromagnetic Separation

Abstract:

According to the structure of a solenoid actuator, transient field mathematic model of two-dimension is established. Based on model, relationship between transient current of the coil and the motion of the armature is analyzed. Compared to experimental results, simulated results are proved, which are able to provide theory basis for displacement detection of electromagnet valve and fault diagnosis of valve and system by inner parameters of solenoid actuator. The results show that the rising current characteristic has the change process of increase-decrease-increase, and separating motion time of the solenoid actuator could be estimated to be 20 ms (18 v). The solenoid actuator is pulled back approximately in 8 ms under the action of the spring.
