Abstract: A rotary position sensor (20, 20 ) featuring a magnetized rotor (10, 10 ) which produces a magnetic flux density that varies sinusoidally with respect to the angular position of the rotor, which may be either a selectively magnetized ring (10 ) or disk (10). The magnetic flux density produced by the rotor is measured by a sensor (30, 30a) that responds in a linear fashion to the magnitude of the radial component of the magnetic flux density. Typical embodiments would use magnetic flux density sensors, as for example either linear Hall sensors or magnetoresistive type sensors. The measured magnetic flux densities are then used as in a traditional resolver to compute position or used to directly generate control signals to operate, for example, a motor.

Abstract: A rotary position sensor (20, 20') featuring a magnetized rotor (10, 10') which produces a magnetic flux density that varies sinusoidally with respect to the angular position of the rotor, which may be either a selectively magnetized ring (10') or disk (10). The magnetic flux density produced by the rotor is measured by a sensor (30, 30a) that responds in a linear fashion to the magnitude of the radial component of the magnetic flux density. Typical embodiments would use magnetic flux density sensors, as for example either linear Hall sensors or magnetoresistive type sensors. The measured magnetic flux densities are then used as in a traditional resolver to compute position or used to directly generate control signals to operate, for example, a motor.
