Abstract:
An inductive angle sensor for determining a rotational position of a rotor relative to a stator includes an exciter coil, at least one pickup coil arrangement having an m-fold symmetry and at least one conductive target having an m-fold symmetry. The exciter coil may excite the conductive target which, in turn, may induce an induced signal in the pickup coil arrangement. A signal analysis device may determine the rotational position of the rotor based on the induced signal. The inductive angle sensor may comprise a second pickup coil arrangement having an n-fold symmetry and a second conductive target having an n-fold symmetry. The exciter coil may excite the second conductive target which, in turn, may induce a second induced signal in the second pickup coil arrangement. The signal analysis device may determine the rotational position of the rotor based on the two induced signals according to a Vernier principle.
