RDD-Series Direct Drive Servo Motors

RDD-Series Direct Drive Servo Motors

Bulletin RDD-Series™ Servo Motors connect directly to the load, eliminating the need for gearboxes, timing belts, pulleys and other mechanical components. The result is reduced energy consumption, faster settling times and better overall control of the load.
