The steady-state operational parameters of a plunger core reactor with
four parallel connected winding paths are 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 sinusoidal
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. With regard to the mechanical design, the
Lorentz forces acting on the windings and the Maxwell forces acting on
the plunger core are additionally calculated in dependence of the plunger
core air-gap.
