About
The Model 820 Rotary Servo Actuator is one of Moog’s most versatile actuators, featuring integral servo electronics and multiple communication interfaces. This high-performance rotary servo electromechanical actuator is designed for extreme conditions and utilizes a brushless DC motor as its prime mover. It is used for surface positioning, throttle control, and other utility functions on UAV and aerospace platforms, and has been chosen to support new and existing programs. Key features include its small size and weight, 28 VDC buss power compatibility, power output up to 230 deg/sec at 60 in-lbs, and torque output up to 150 in-lbs. It incorporates a brushless permanent magnet motor design, position and torque limiting, high accuracy film transducer, and position output signal/feedback. The actuator operates with various command inputs, has a low backlash design, and offers stroke or displacement up to ±45 degrees, with Moog evaluating higher angular performance requirements as needed. It also features high efficiency steel gearing. Benefits include a robust structural design, mechanical stops, low weight to power performance, and customizable options. Typical applications include unmanned air vehicles (tactical, MALE, HALE) for flight control surface actuation, optionally piloted vehicles (OPV), utility actuation (throttle control, doors, spoilers), and electric aircraft (eVTOL, eSTOL, air taxis, urban air mobility vehicles) for tilting mechanisms, flight control, and landing gear.
