Magnetic powder brake and steering system

Abstract

A magnetic powder brake (1) comprising a stator (10) and a rotor (11) arranged to rotate about an axis of rotation (14) with respect to the stator (10), and comprising a coil (12) arranged on the stator (10), wherein at least a first shear gap (21) for receiving ferromagnetic powder is formed between the stator (10) and the rotor (11), and the coil (12) is arranged radially inside with respect to the shear gap (21), characterized in that the magnetic powder brake (1) comprises a shaft (13) for transmitting torque to the rotor (11), wherein the shaft (13) is arranged radially inside the stator (10). i) radially further out, or ii) is arranged radially further inwards, wherein the magnetic powder brake (1) comprises an angle sensor with which an angular relative movement between the stator (10) and the shaft (13) can be detected, wherein the shaft (13) is arranged radially further inwards with respect to the stator (10) and the rotor (11) and / or at least one torque transmission element (37) between the rotor (11) and the shaft (13) is designed to be torsionally flexible such that when the rotor (11) is fixed relative to the stator (10) and a torque is introduced into the shaft (13) an angular relative movement between the shaft (13) and the stator (10) can be carried out.
