The Model 220 is a high performance rotary servo electromechanical actuator that utilizes rare earth brushless DC motors, magnetic encoder and position loop control electronics all integrated into one compact package. It is well suited for aerospace and unmanned airborne platforms due to its high performance and small envelope. It can also be used in a variety of applications as it is a self-contained servo motion solution. Although it is specified with a 7,500 hour life, Moog has tested the Model 220 actuator, meeting 16,000 hours, and the unit was still operating within specifications.
The 220 actuator is one of our most versatile designs, and it is offered in multiple variants including RS-485 digital and RC / PWM analog communications. Moog also has a design that develops twice the peak torque.
