COIL ASSEMBLY FOR INDUCTIVE ENERGY TRANSMISSION, INDUCTIVE ENERGY-TRANSMISSION DEVICE, AND METHOD FOR PRODUCING A COIL ASSEMBLY FOR INDUCTIVE ENERGY TRANSMISSION

摘要

The invention relates to a coil assembly (1) for inductive energy transmission, comprising: an electrically non-conductive substrate (2), which has a first side (10) and a second side (11); a plurality of conducting tracks (30), which are arranged on the first side (10) and on the second side (11) of the substrate (2) and which form a coil (50) for inductive energy transmission; a plurality of vias (4) in the substrate (2) for feeding the conducting tracks (30) through the substrate (2); wherein at least two of the plurality of conducting tracks (30) are arranged in a twisted manner in relation to each other in the substrate (2). The invention further relates to an energy transmission device and to a method for producing a coil assembly (1) for inductive energy transmission.
