Experimental Verification of 0.4 Nm Torque of a Mini-CMG Module with a Scissored-Pair Structure

In this paper, a mini control moment gyroscopic (CMG) actuator with a scissored-pair is designed and implemented. Two single gimbal CMGs form a double gimbal CMG mechanically to generate the double torque in the desired direction. The mechanical design of the worm gear mechanism allows the scissored-pair configuration. Experimental studies for measuring the induced torque using a force sensor are conducted. The estimated design torque and the measured torque are compared. We actually obtain a 0.4 Nm induced torque.
