MoogModel 863 -Rotary Servo Electromechanical Actuator

SHARE

The Model 863 is a high performance rotary servo electromechanical actuator that integrates a rare earth brushless DC motor and servo loop control electronics. The 863 servo is used for flight control, throttle control and other utility functions for UAV and aerospace programs.  These actuators are designed to operate under extreme environmental conditions and customers find them easy to implement into their systems. This model is designed to be submersible up to 3 meters for a maximum of 3 hours, allowing it to be used on multiple applications including target drones.
