Original Kurzfassung:
In modern injection systems and pneumatic valves, solenoid valves are widely spreaded for a volume flow control. The recent literature covers the influence of eddy current on the dynamic response for solenoid valves in depth. Basically pot core assemblies were taken into account and small air gap scenarios were investigated. The large scale actuators like high force lifting magnets are regarded in the present work and the proposed model is not limited to pot cores, because end effects are considered. The inverter operation opens opportunities for different excitation voltages and a high precision model including nonlinearities is required for the loss reduction of the total actuator. It is shown that the proposed model exhibits a promising coherence with the measurements. The proposed model utilizes magnetic equivalent circuits and quasi-static finite elements methods.
