CONTACTLESS POSITION MEASUREMENT OF ROTATING ELEMENTS

摘要

The invention relates to an arrangement for measuring the position or rotational speed or rotational direction in a bearing for a shaft element (1, 1a). Said bearing comprises a stationary section (10) on which the shaft element (1, 1 a) is rotatably supported, and the shaft element comprises at least one sensor (30) which can rotate with the shaft element (1) and is fixed thereto. Antenna rings (41, 40) are respectively provided on the stationary section (10) and on the shaft element (1, 1a), said antenna rings being connected by capacitive signal coupling.
