SYSTEM AND METHOD FOR REDUCING ROTATION NOISE IN A MAGNETOELASTIC TORQUE SENSING DEVICE

A system and method for creating one or more magnetically conditioned regions on a rotatable shaft or disk-shaped torque sensing element, wherein rotation noise produced by the element due to magnetic field variations is substantially negated. Upon magnetization of the torque sensing element, rotati...

More Information
Summary:A system and method for creating one or more magnetically conditioned regions on a rotatable shaft or disk-shaped torque sensing element, wherein rotation noise produced by the element due to magnetic field variations is substantially negated. Upon magnetization of the torque sensing element, rotation noise produced by the magnetically conditioned region is measured. Adjustment factors are calculated based on the measured rotation noise, and the adjustment factors are used to adjust a magnetic field source during subsequent magnetization of the torque sensing element.
