Lumped Modeling of Magnetic Actuator Using the Inverse Magnetostrictive Effect

A plunger-type magnetic actuator is proposed for easier control of displacement, and is subjected to lumped modeling to relate the energy conversion between the Piezo and MM using the inverse magnetostrictive effect. Magnetic flux density and magnetic force in the magnetic actuator are simulated by using a magnetic analysis program. The lumped model was compared with the FEA model. The difference between two methods is within 10%
