Tensor Tech CMG-10m Control Moment Gyroscope

CMG-10m is a variable-speed, single-gimbal Control Moment Gyroscope (CMG) which is suitable for 3U CubeSats. Unlike traditional CMGs that are driven by two or three motors, this CMG is driven by only one spherical motor, making it capable of minimizing into a CubeSat form factor. Serving as an attitude actuator component, the CMG-10m has to be commanded by the user’s onboard computer (OBC) or ADCS computer. Torque and speed modes are available for the OBC or ADCS computer to switch between.
The user’s controller design can be simplified by adopting the torque mode. However, the output torque is only accurate when the satellite has a tumbling rate of < 1 deg/second. The speed mode allows the user to manipulate the inner rotor speed and the gimbal angle. It is designed for advanced users who will derive the CMG steering and control laws by themselves.
