Contactless Energy Transfer to a Moving Load Part I: Topology Synthesis and FEM simulation

In this paper a new topology for contactless energy transfer is proposed that can transfer energy to a moving load using inductive coupling. The load is attached to a planar motor that is magnetically levitated and propelled by the same coils that transfer energy to the moving load. The proposed coil geometry is very tolerant to misalignments of the secondary coil with respect to the primary coil and has the capability to transfer power continuously to the moving load at every position
