    Abstract: A rotary actuator includes a stator assembly positioned within an outer enclosure. A rotor assembly is positioned adjacent to the stator and is configured to rotate relative thereto and about a centerline axis of the rotary actuator. Each of the outer enclosure, the stator assembly, and the rotor assembly are arranged to carry a magnetic flux therethrough and form a flux path loop, such that as a magnetic flux flows through the outer enclosure, the stator assembly, and the rotor assembly, a torque is generated by rotation of the rotor assembly relative to the stator assembly.
