Abstract: A system includes a helically polarized magnet having a plurality of north and south poles circumferentially and helically patterned along a linear axis. Magnetic flux varies at different positions along a linear path in a direction aligned with the linear axis. A multi-axis magnetometer and/or magnetometer array is configured with at least two sensing coils to detect the position of the helically polarized magnet by sensing the magnetic flux variations at the different positions along the linear path.

Abstract: In the particular embodiments described in the specification, a permanent magnet synchronous machine includes a stator with a plurality of stator coils and a rotor within the stator having a plurality of permanent magnets disposed around its periphery, and position detectors for detecting the horizontal, vertical and axial positions of the rotor within the stator. A magnetic bearing control arrangement generates control signals based on deviations of the rotor position from a desired position and supplies corrective signals to the stator coils and a motor control arrangement detects the angular position and speed of the rotor within the stator and supplies signals to the stator coils simultaneously with the magnetic bearing control signals to control the angular position and rotational speed of the rotor.
