Abstract

The system 1 according to the invention comprises an energizable load 2 and an inductive powering device 9 and a permanent magnet 8 arranged on the conductor 4 for interacting with the further conductor 9a for aligning the inductor winding 6 with respect to the further inductor winding 9b. The energizable load 2 for enabling the inductive power receipt comprises a wiring 6 which cooperates with the conductor 4 for forming a secondary wiring of the transformer. In order to form the system for inductive energy transfer, the energizable load 2 is to be placed on the inductive powering device 9, whereby the surface 2a will contact the surface 7. The inductive powering device 9 comprises a further magnetizable conductor 9a provided with a further winding 9b thus forming a primary wiring of the split-core electric transformer. When the winding 6 is brought in the vicinity of the further winding 9b, the magnetic force acting on the further magnetizable conductor 9a serves for an instant proper mutual alignment of the winding 6 and further winding 9b. The invention further relates to a inductive powering device, an inductive load and a method for enabling an inductive energy transfer to en…
