Electromechanical Rotary Actuators

Gun/Turret/Radar Drives for Naval Systems

Moog’s series of high-torque, direct-drive, brushless motor, rotary actuators is designed for combat turret applications. They meet or exceed the demanding requirements of military environments to include the high-salt content of sea air, while offering world-class weapon pointing, stabilization, and improved slew rates for existing and new weapon turret systems. This series of high-torque motors eliminates the need for a gearbox between the motor and load and provides low-drive inertia for superior stabilization performance and high stiffness with a backlash free coupling. This electromechanical rotary actuator includes an integrated clutch/noback with a manual drive input.




Moog is a worldwide designer, manufacturer, and integrator of custom precision motion control and stabilization systems for the defense industry. Our electromechanical rotary and linear actuators are ideal for new systems, upgrading from older hydraulic systems, and sustainment service applications.
