Abstract / Hauptanspruch
A measuring system for determining an angle of rotation of a shaft, which is rotatable about an axis of rotation, having a magnetically conductive encoder, which is spaced from the axis of rotation and fixedly connected to the shaft, a magnet unit with a permanent magnet, and an intermediate sensor unit having two magnetic field sensors. The permanent magnet has a magnetization extending parallel to the axis of rotation, and a circular-cylindrical recess having a bottom, an axis of symmetry extending perpendicular to the bottom, and a diameter, the sensor unit being completely arranged within the recess and stationary with respect to the permanent magnet. The first distance of the encoder from the axis of rotation being less than half the diameter of the recess, the encoder being arranged in a direction parallel to the axis of rotation at a second distance from the sensor unit.
