Abstract:
1. An actuator motor, comprising: a rotor comprising a rotor shaft and a plurality of contiguous magnets attached to a circumference of the rotor shaft and configured according to an optimized array that produces a plurality of rotor magnetic fields having augmented flux densities exterior to the rotor and diminished flux densities within an interior of the rotor; and a stator comprising a stator core aperture sized for receiving the rotor, the stator comprising a plurality of stator windings configured to create one or more stator magnetic fields that when introduced to the plurality of rotor magnetic fields, induces a torque on the rotor shaft, wherein the plurality of stator windings each comprise a plurality of parallel strands of conductors wrapped around a stator tooth such that a packing density of parallel strands increases along a radial axis from an innermost edge of the stator tooth to an outermost edge of the stator tooth.
