Actuator for control loading system

摘要

An actuator which can be installed in a system for the virtual simulation of aircraft, ships and vehicles to help the system with the controls. More specifically, the invention is an actuator used for a control loading system, which can be installed into a virtual simulation system, receive force delivered by the movement of a control stick laterally while measuring the applied force. It can connect a lever which delivers the control force equivalent to the applied force and reaction force by making use of a direct drive motor, including a potentiometer which senses the angle of rotation while sensing the initial reference position separately from an encoder, limiting the rotation range of the rotating lever, fixing the initial neutral position, and the control loading system for actuators manufactured compactly on the whole.

主权项

1. 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, andan 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, anda 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.
