Rotary Actuators Offer 15 Arc-Seconds Accuracy
Integrating a cross-roller bearing structure, Oriental Motor’s DG 200 Series hollow rotary actuators shows a repetitive position accuracy of 15 arc-seconds and a total backlash of 2 arc-minutes. With a frame size of 7.87” (200 mm) and an internal hollow diameter of 3.94” (100 mm), the RoHS-compliant components develop 440 lb/in. (50 Nm) of torque at speeds of up to 110 rpm for positioning larger inertial loads. The actuators use the AlphaStep stepping motor and controller, and equipment tables and arms can be installed on the output table.
