Magnetostrictive Torque Sensor.

Abstract

Magnetostrictive wire having a low surface-to-volume ratio established by a constant non-planar cross-section, is helically deformed into contact with a shaft under a stress maintaining the wire in fixed relation to the shaft surface. Magnetic anisotropy is imparted to the wire by twist thereof about its cross-sectional axis while the wire is being helically deformed into contact with the shaft surface to form a torque sensor through which accurate torque detection is achieved. Patent Applications. (RH)
