Abstract
Two magnetic field generators are located symmetrically to each other in a first plane perpendicular to a shaft, and two magnetic field detectors are immobilized in a second plane perpendicular to the shaft. The magnetic field detectors provide a signal proportional to the torsional moment as a result of angular shift of the magnetic field generators with respect to the magnetic field detectors. The magnetic field generators have a magnetized structure with antiparallel magnetization directions and are supported by a first disk mounted on the shaft and are placed at the end of a first hub which surrounds the shaft. The first hub supports a bearing for mounting a second hub and second disk, which is axially shifted and to which the magnetic field detectors are rigidly attached.
