Abstract
A torque sensor has a magnetic foil which is wound and attached to a rotating shaft in strip form at an angle to the shaft axis of rotation, the magnetic strip being mechanically stressed dependent upon the torque acting on the shaft, and generating voltages in two secondary windings surrounding the magnetic strips. The voltages will be different due to different forces acting on the two strips, this being a measure of the torque acting on the shaft. The strips are formed from stamped segments cut obliquely from an amorphous tape which is cast with a profiled cross-machine cross section having regions of varying thickness. Such a tape can be manufactured using a nozzle having a correspondingly shaped orifice opening through which molten amorphous alloy is discharged onto a moving cooling surface.
