SYSTEMS AND METHODS FOR REDUCING ROTATION NOISE IN A MAGNETOELASTIC DEVICE AND MEASURING TORQUE, SPEED, AND ORIENTATION

摘要

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, and a system and method for creating one or more magnetically conditioned regions on a rotatable shaft or disk-shaped element to allow the element to function as part of a rotational speed or rotational position sensing device.
