High Performance Rotary Actuators

Moog's line of rotary electromechanical actuators offers products that are affordable, robust and designed for naval shipboard environments.  These actuator designs are based on Moog's product heritage in aerospace, military and industrial markets.  

Moog has the capability to design a solution to fit any Navy application.  Actuators can be provided in power ranges from fractional to over 100 horsepower.  One of Moog's strengths is designing actuation systems requiring precise motion control at high bandwidths.  Moog can provide the control systems engineering needed to tune the actuation system for optimal performance.


Product Features

Moog has designed and built rotary actuator systems for undersea control surface and propulsion applications. In these applications, the actuators are designed to withstand a lifetime of undersea exposure.
