The steady-state and transient operational behaviour of a plunger core
reactor with four parallel connected winding paths is calculated from
voltage driven finite element analyses. Thereby, the 3D finite element
model utilizes a direct circuit coupling to take into account for the
applied voltage and the parallel windings paths. Consequently, the
distribution of the coil currents is obtained with the full influence of
the axial position of the plunger core. Moreover, the Lorentz forces
acting on the windings and the Maxwell forces acting on the plunger core
are calculated in dependence of the plunger core air-gap.
