Control-Motor-Generator Group

A Control-Motor-Generator (CMG) group is a system used in aerospace engineering to control the attitude and orientation of a spacecraft. It consists of three main components: the control moment gyroscope (CMG), the motor, and the generator.

The CMG is a spinning wheel that can be controlled to produce torque, which is used to change the spacecraft's orientation. By changing the speed and direction of the CMG, the spacecraft can be maneuvered and stabilized.

The motor is responsible for driving the CMG and maintaining its desired speed. It provides the necessary power to keep the CMG spinning at the desired rate.

The generator is used to convert the mechanical energy produced by the CMG into electrical energy. This electrical energy can then be used to power other systems on the spacecraft.

Together, these three components form the CMG group, which is an essential part of spacecraft control systems.
