ABSTRACT:
A torque sensing apparatus for picking up a magnetic field of a magnetostrictive material disposed on a shaft, the torque sensing apparatus having: a first integrating ring; a second integrating ring; a first fluxgate return strip and a second fluxgate return strip each being connected to the first integrating ring at one end and the second integrating ring at the other end; an excitation coil; and a feedback coil; wherein the first integrating ring and the second integrating ring are configured to be positioned to pick up flux signals along the entire periphery of the ends of the magnetostrictive material.
