Abstract
A module having an angle-sensor mechanism, an energy-transmission device and an information-transmission device comprises at least two circuit boards (1, 2). One circuit board (1) forms the stator with respect to the angle-sensor mechanism, while the other board (2) forms the rotor with respect to the mechanism. The stator includes the primary coil for the angle-sensor mechanism, as well as an exciting coil for the transmission of energy and information. The rotor includes the secondary coil of the angle-sensor mechanism, as well as a receiver coil, for the transmission of energy and information. The exciting coil and the receiver coil are disposed in circular fashion on the respective circuit board, thereby creating a coupling for the exciting coil and the receiver coil that is independent of the angle. The exciting coil and the receiver coil are used for transmitting both energy and information. The energy transmission is typically effected with a medium frequency of, for example, 25 kHz. A modulation is superposed on this medium frequency for transmitting information. Various modulation methods are feasible, such as HF (high-frequency) modulation, amplitude modulation or phase modulation.
