Device for the sensory detection of rotational movements

摘要

A device for detecting rotational movements about an axis of rotation is proposed. The device comprises a magnet arrangement for generating a useful magnetic field and a first and a second sensor for detecting the rotational movements, in particular the speed and / or the position. To simplify the construction of the device and to increase the resolution of the device, the magnet arrangement comprises a homogeneous area which is provided for scanning by the first sensor and an area with alternating polarity which is provided for scanning by the second sensor.
