The Servo Cylinder is a popular choice for high reliability UAV control surface and utility linear actuator applications. The A-Series Servo Cylinder uses a brushless DC motor and contactless absolute position feedback to reduce wear and provide superior performance when compared to potentiometers and brushed DC solutions. The built-in control electronics offer a variety of communication interfaces including RC PWM, 4-20 mA in/out, ±10 VDC, RS-232, RS-422, and CANopen.
Our AM Servo Cylinder is designed to excel in harsh shock/vibe environments with IP65 dynamic and IP67 static ingress protection ratings. The D38999 receptacles provide military standard connections, and the on-board temperature, current, voltage, and humidity sensors allow for constant health monitoring of the servo actuator. Custom heater firmware is available that maintains a configurable controller temperature even in ambient environments < -40°C. The Servo Cylinder has an 8 to 36 VDC operating bus voltage, which is compliant with the majority of UAV power busses and will survive at >51 VDC.
The Servo Cylinder offers forces up to 530 lbf, strokes up to 7.75 inches, and speeds up to 14 in/s, allowing for high bandwidth control >15 Hz at small position amplitudes.
Conversions of control surfaces from rotary actuators to linear actuators can lead to increased performance and decreased cost/mass.
