Constant magnetomotive force
Extends from Interfaces.TwoPortElementary (Interface component with two magnetic ports for textual programming).
Information
Magnetic circuits under steady-state conditions, i.e., with stationary magnetic fields (change of magnetic flux dΦ/dt = 0) can be described with constant sources of a magnetic potential difference or magnetomotive force (mmf). Constant magnetic potential differences are imposed by
- coils with stationary current (di / dt = 0) and
- permanent magnets modelled with Thévenin's equivalent magnetic circuit.
For modelling of reluctance actuators with this source component it is assumed that the armature is fixed so that no motion-induced flux change dΦ/dt can occur.
