Abstract
An speed sensor for a rotating shaft includes a plurality of magnetic portions on the shaft that output a magnetic field from each of the magnetic portions, wherein the magnetic portions are integrally formed in the shaft by magnetically polarizing the shaft material itself. At least one magnetic field sensor is positioned proximate to the shaft for detecting the magnetic field from each of the magnetic portions and for outputting a signal corresponding to the angular speed of the shaft as the shaft rotates. The signal is useful for calculating the angular speed of the shaft, and the calculated angular speed value is useful for things like adjusting the angular speed of the shaft, monitoring the performance of the system in which the shaft is used, and for other purposes.
