Abstract
A torque sensing system having a torque sensor, and a steering system, are provided. The torque sensor includes a first rotor having apertures extending therethrough and bar magnets disposed in the apertures. The torque sensor further includes a second rotor defining an interior region with the first rotor being disposed in the interior region. The second rotor has tooth members extending toward the first rotor. The torque sensor further includes first and second Hall effect sensors disposed in an open region of the second rotor proximate to the first rotor. The first and second Hall effect sensors generate first and second signals, respectively, indicative of an amount of torque applied between the first rotor and the second rotor.
