An electric propulsion system for use with a mast defining an axis of rotation and one or more rotor blades which rotate about the axis of rotation, includes a yoke assembly, electric motor, motor support housing, and overrunning clutch. The yoke assembly is rotatable with respect to the mast, and configured to support one or more of the rotor blades. The motor includes a motor-stator and a motor-rotor, and is arranged circumferentially around the mast. The housing circumferentially surrounds the mast and includes a rotatable portion attached to and rotatable with the yoke assembly. The overrunning clutch includes an inner hub rotatable with the motor-rotor, and an outer hub rotatable with the rotatable portion of the housing. The overrunning clutch is configured to transfer torque from the motor to the yoke assembly in a drive mode, and configured to disengage the yoke assembly from the motor in an overrunning mode.
