Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Moving coil actuators are often called electrodynamic actuators and a proportional behaviour between force and current is expressed by a converter constant (see ConstantActuator). However, in a simple moving coil actuator as presented in this example there is an additional non-linear force component that is due to the increase of the inductance when the armature coil moves into the ferromagnetic stator. A simple PermeanceActuator can be used to describe this non-linear force component.
