Abstract:
An inductive angle sensor is provided with a stator with an excitation oscillating circuit and a pickup coil arrangement and also with a rotor which is arranged rotatably with respect to the stator and comprises an inductive target arrangement. The excitation oscillating circuit can be energizable with an alternating current, in order to induce an induction current in the target arrangement, and the target arrangement can be designed to generate a magnetic field in reaction to the induction current, which magnetic field in turn generates induction signals in the pickup coil arrangement. The angle sensor further comprises a circuit that is designed to derive an induction strength signal representing the signal strength of the induction signals from the induction signals and to ascertain the spatial clearance between the rotor and the stator on the basis of the induction strength signal, and to generate a corresponding clearance signal.
