Abstract
A bearingless angular measurement device includes an angle scale, a scanning unit, and an evaluation electronics. The scanning unit and the angle scale are located at a scanning distance relative to each other and are rotatable about an axis, so that the scanning unit is capable of generating angle-dependent output signals, which may be further processed in the evaluation electronics. The scanning distance is able to be determined on the basis of the output signals. In addition, the angular measurement device includes a compensation coupling that is attachable to a machine component and is elastically deformable in the direction of the axis.
