SYSTEM AND METHOD FOR SENSING TORQUE AND ANGULAR POSITION OF A SHAFT

摘要

A system and method for sensing torque and angular position of a rotating shaft may include a shaft with a magnetostrictive ring affixed to the shaft. The magnetostrictive ring may generate position-dependent magnetic fields relative to the shaft's rotation. A first sensor may measure a magnetic field that varies with angular position. A second sensor may measure a magnetic field that varies with torque.
