Device for wireless energy supply and data transmission for a transponder in a rotatable system with low-energy applications

摘要

Device 100 for wireless power supply and data transmission for a transponder in a rotatable system. The device comprises a shaft 110, a coil carrier 130, which is arranged at a distance from the shaft 110, and a primary coil 135, wherein the primary coil 135 is arranged on the coil carrier 130. The primary coil 135 generates a magnetic field in which a secondary coil 115 can rotate. The secondary coil 115 is disposed on the shaft 110. According to the invention, the primary coil 135 and the secondary coil 115 are spaced apart from one another and arranged concentrically around the shaft relative to one another such that signals and energy can be transmitted.
