Product Overview

Linear Servo Actuator Control System is used to precisely control the linear type servo actuators such as wing flaps, nose wheels, and tail flaps while at the same time deploying and retracting the landing gear system in aircraft. The data received from the drive Hall Effect Sensor’s position and speed are controlled according to the vector control algorithm and this controller carries out the driving of the motor according to the structure. It can receive commands via the RS-422/RS-485 communication interface with the flight control computer.
