Abstract
A rotary motion detector includes an electrically conducting induction element formed essentially as a hollow cylinder and rotatable about a rotation axis. An excitation assembly applies an inhomogeneous magnetic field and induces an eddy current in the induction element, when the induction element rotates about the rotation axis. A sensor assembly detects a measurement signal that depends on the eddy current. The excitation assembly and the sensor assembly are both arranged radially inside the induction element.
