Modeling a magnetomechanical drive by a coupled magnetic, electric, and mechanical lumped circuit approach

In electromagnetic drives and actuators electric, magnetic, and mechanical phenomena have to be solved for simultaneously. Moreover, the device is frequently fed by a power supply including components of power electronics. This article shows how the magnetomechanical drive can be modeled by lumped circuit elements and then be simulated together with the external electrical circuit and a mechanical load in a circuit simulation package. The circuit is easily designed and it considers both eddy currents and hysteresis in the magnetic device by means of a dual Cauer circuit.
