Abstract
Magnetically encoded shafts for use in detecting forces exerted on the shaft during operation. Magnetically encoded regions, arranged in tracks or bands, encircle the shaft and are formed within or affixed to the shaft. The magnetically encoded regions define force-sensitive regions therebetween. Magnetic fields surround the force-sensitive regions and are altered by force vectors passing through the force sensitive region. These magnetic fields are sensed by magnetic field sensors to determine various shaft parameters including, for example: shaft rotational speed, shaft rotational position, and forces exerted on the shaft, e.g., torque, bending forces, stress forces and strain forces. To provide continuous detection of shaft operational parameters and forces, dead zones between magnetically encoded regions are aligned with force sensitive regions associated with magnetically encoded regions in other bands.
