Abstract
Systems, methods, and apparatus for differential magnetic field torque sensors that include first and second magnetic targets for coupling to one or more rotatable shafts. The magnetic targets can include multipole ring magnets having a plurality of alternating magnetic domains. First and second differential magnetic field angular position sensors positioned proximate to the magnetic targets produce angular position of the targets and a processing unit is operative to receive an angular position from each of the first and second differential magnetic field angular position sensors and determine a difference between the angular positions. The difference corresponds to an angle between the targets, and the processing unit is operative to calculate, based on the angle, a torque applied to the one or more rotatable shafts.
