Abstract
A rotation angle measurement system for detecting a rotation of a shaft. The rotation angle measurement system includes the shaft which extends in an axial direction, a rotor unit having a sensor magnet, a stationary stator unit having a multi-turn sensor unit which is arranged radially spaced apart from the shaft and which has a Wiegand sensor, and a magnetic shielding arrangement for the Wiegand sensor. The rotor unit is connected to the shaft to rotate therewith and radially surrounds the shaft. The multi-turn sensor unit functionally interacts with the sensor magnet to detect revolutions thereof. The magnetic shielding arrangement is made from a material having a high magnetic permeability. The magnetic shielding arrangement includes shielding elements which are arranged to surround the Wiegand sensor on a radial inside, on a radial outside, on a first axial side, and on a second axial side thereof.
