About
The Moog Model 974 Linear Servo Actuator is engineered for demanding aerospace applications, specifically for positioning the nacelles on tilt rotor unmanned aerial vehicles during critical flight conversion modes. This actuator is built to withstand extreme environmental conditions and offers exceptional endurance, ensuring reliable performance in challenging operational scenarios. Its robust structural design incorporates two NFeB Permanent Magnet DC brush motors and two failsafe electromagnetic brakes for enhanced safety and control. The actuator features low endplay and high-efficiency steel gearing, contributing to its precision and durability. It utilizes a trunnion mount for the fixed end and a traveling nut endfitting, along with a ball screw/nut power screw assembly. With a compact size of 3.88 x 4.75 x 14.75 inches and a weight of 8.1 lbs, it delivers a force of 1,500 lbs at a rated power point of 0.26 in/sec, and has a rated stroke of 7.25 inches. The no-load speed is 0.87 in/sec, powered by 28 VDC.
