<p>An inductive angle sensor includes: a stator element having an exciting coil with a periodic AC voltage applied thereto and several receiving coils; a rotor element that affects a strength of inductive coupling between the exciting coil and receiving coils as a function of its angular position relative to the stator element; and an evaluation circuit for determining an angular position of the rotor element relative to the stator element from voltage signals induced in the receiving coils. The rotor element forms at least one closed-loop lead that, at least over a partial area, forms a periodic repeating bend structure in a direction of a circumference of the rotor element. The inductive angle sensor provides a compact structure, a high resolution, and a particularly high degree of insensitivity to production and installation tolerances.</p> |
