How large (mass) are the CMGs on the ISS? What is the minimum torque they apply? What is the maximum torque they apply?

    $\begingroup$ It is helpful to show some of the research you have already done. Is there a page showing info about the CMGs that does not list this info? Then perhaps give us a link to it. Also abbreviations such as CMG are always good to define for the benefit of other readers who find this question in the future. $\endgroup$ – OrangePeel52 May 16 '17 at 13:20

The L-3 Communications Control Moment Gyroscopes (CMGs) used on the ISS have specifications detailed in the L-3 CMG Control Moment Gyro datasheet. Here are the properties you are looking for:

Weight 600 lb., 272 kg

Maximum Output Torque 258 Newton-meter

It's not specified, but I see no reason why the minimum torque wouldn't be zero.
