Abstract
An electric propulsion system includes a static mast defining an axis of rotation and a stationary rotor hub assembly coupled to the static mast. A rotating system is rotatably mounted to the stationary rotor hub assembly. The electric propulsion system additionally includes an electric motor including a stator assembly associated with the rotor hub assembly and a rotor assembly associated with the rotating system.
