  • Torque sensing system having torque sensor, and steering system
    Patent number: 8726742
    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.

  • PERMANENT MAGNET BRUSHLESS MOTOR
    Publication number: 20120126654
    Abstract: A permanent magnet brushless motor is provided. The motor includes a stator having a tubular-shaped member and a plurality of tooth members extending radially inwardly from the tubular-shaped member. Each tooth member has an arcuate-shaped convex surface disposed proximate to an interior region defined by the stator. Each arcuate-shaped convex surface is defined by a first radius that is rotated about a respective center point that is disposed radially outside of the stator. The motor further includes a rotor disposed within the interior region of the stator.
