Model 220 Rotary Servo Actuator
Product Specifications
The Model 220 is a high performance rotary聽servo electromechanical actuator that utilizes聽rare earth brushless DC motors, magnetic聽encoder and position loop control electronics聽all integrated into one compact package. It is聽well suited for aerospace and unmanned聽airborne platforms due to its high performance聽and small envelope. It can also be used in a聽variety of applications as it is a self-contained聽servo motion solution. Although it is specified with a 7,500 hour life, 刘玥首次大战黑人has tested聽the Model 220 actuator, meeting 16,000 hours, and the unit was still operating within聽specifications.
