About
The TensorCMG Series features a variable-speed, single-gimbal Control Moment Gyroscope (CMG) driven by spherical motor technology. This innovative design significantly reduces weight, volume, and power consumption (SWaP) compared to traditional CMGs. An autonomous torque calculation algorithm is integrated directly onto the control board, allowing for multi-axis torque output through simple commands. The TensorCMG-10m model is specifically engineered for CubeSats up to 16U and nanosatellites weighing up to 30kg, boasting flight heritage since 2022. Key features include optimized torque-to-power ratio, a form factor that fits the ‘tuna-can’ standard, soft error and hard error fault detection, and low jitter (micro-vibration) meeting ISO1940 G0.4 at 8000rpm. Magnetic leakage flux is shielded with a Ni-iron alloy. The device operates by maintaining a spinning rotor at a variable speed via spherical motor actuation, with the rotor mounted in a gimbal frame that allows its spin axis to tilt. When the gimbal tilts the rotor’s spin axis, the spacecraft experiences torque due to the conservation of angular momentum, inducing rotation of the spacecraft. The TensorCMG-10m is available in both integrated and discrete configurations to accommodate various satellite architectures. The integrated assembly mounts within the ‘tuna-can’, occupying 0.25U and maximizing internal payload volume. Discrete configurations allow for separate installation of the CMG, controller, and sensors within the satellite structure, occupying 0.75U total and providing flexible component positioning for non-standard layouts. The discrete version also supports custom adapter structures or purchasable adapter options. Two mount configurations are available: vertical mount and skew mount (with an External Driving Module), with the skew mount offering a 53-degree skew angle for pyramid cluster formation.
