Abstract: A variable reluctance stepper motor comprises a stator and a rotor that is rotatable relative to the stator. The stator comprises an annular outer yoke with a set of circumferentially spaced stator poles at equal angular intervals around the yoke extending radially inward from first portions of the yoke toward the rotor. Phase windings are individually coiled around each of the respective stator poles. Multiple slots are formed in an outer perimeter edge of the yoke at second portions thereof circumferentially situated between the first portions. A permanent magnet is embedded within each slot with circumferentially directed magnetic orientation of the respective permanent magnets. The remote placement of the magnets ensure that detent torque is kept to a minimum, while also increasing holding and dynamic torque levels.
