CMG SERIES
Control Moment Gyroscope
The TensorCMG Series is a variable-speed, single-gimbal CMG driven by spherical motor technology. This spherical motor design reduces weight, volume, and power consumption (SWaP). An autonomous torque calculation algorithm is integrated on the control board, enabling multi-axis torque output through simple commands.
The TensorCMG-10m is designed for CubeSats up to 16U and nanosatellites up to 30kg with flight heritage since 2022.
Features
Torque-to-power ratio optimization
Form factor: fits tuna-can standard
Soft error and hard error fault detection
Jitter (micro-vibration): ISO1940 G0.4 @ 8000rpm
Magnetic leakage flux shielded with Ni-iron alloy
A spinning rotor is maintained at variable speed through spherical motor actuation. The rotor is mounted in a gimbal frame, allowing the spin axis to tilt.
When the gimbal tilts the rotor's spin axis, the spacecraft experiences torque due to conservation of angular momentum, inducing rotation of the spacecraft.

INSTALLATION
INTERFACES
The ADCS is available in integrated or discrete configurations to accommodate different satellite architectures.
1) Integrated assembly mounts in the tuna-can occupying 0.25U and maximizing internal payload volume.
0.25 U for installing in the tuna-can
2) Discrete configurations allow separate installation of CMG, controller, and sensors within the satellite structure occupying 0.75U total and providing flexible component positioning for non-standard layouts.
0.75 U for installing inside the CubeSat
VERSATILE CMG FOR
SATELLITE INTEGRATION
The TensorCMG-10m is available in integrated and discrete versions.
The discrete version supports custom adapter structures or purchasable adapter options.
Two mount configurations are available: vertical mount and skew mount (with External Driving Module).
The skew mount configuration includes a 53-degree skew angle for pyramid cluster formation.
