About
Linear actuators translate rotary motion to linear motion and share similar features and applications with rotary units. This configuration is designed to control linear motion, utilizing high-performance DC motors coupled to high-efficiency gearing. Typically, a ball screw or lead screw/nut assembly is employed to convert rotary to linear motion. These actuators often integrate a position transducer and a fail-safe brake within a robust structural design. Moog can pair the actuator with position loop servo control electronics and offers redundancy options through the motor and feedback device. With over 35 years of experience, Moog provides in-house design, manufacturing expertise, engineering support, and qualification for these products. Products range from 100 to 2,000 lbf for linear configurations, and assemblies can be offered with integral servo control electronics. Moog supports various communication interfaces including analog (+/- 10 VDC), RS232/422/485, R/C PWM, and CAN Bus, and can design for redundancy as required by the customer.
