Patent ID: 8746627

Claim:
An actuator for a control loading system comprising: a direct drive motor including a stator, a rotor configured to rotate around the stator and to interact with the stator electrically, and an encoder configured to sense an angle of rotation of the rotor, wherein the stator is fixed in a stator body and the rotor is fixed in a rotor body; a fixture including an upper fixture supporting the rotor body of the direct drive motor, a lower fixture supporting the stator body of the direct drive motor, and a potentiometer arranged in a rotation axis in the direction of the rotor body; and a rotator including a lever having a first end fixed at a pivot on a top of the rotor body and a second end configured to rotate horizontally around the pivot, a shaft rod installed perpendicular to the rotor body and having a bottom end fixed on a shaft of the potentiometer; and a force sensor having a first end connected to the lever for horizontal rotation and a second end configured to receive a force applied to a control stick, wherein the force sensor generates an electric signal according to an amount of deformation corresponding to the magnitude of the applied force.
