CubeSpace
CubeWheel is a satellite reaction wheel that came in small, small+, medium and large sizes. The following Gen1 CubeWheels have been replaced by their Gen2 counterparts: CubeWheel Small = Gen2 CW 0017, CubeWheel Small+ = Gen2 CW0057, CubeWheel Medium = Gen2 CW0162.

CubeWheel includes a highly balanced flywheel disc, a brushless electrical motor, an electronic driver and a microcontroller circuit. The wheels can be given a speed reference command through I2C, UART or CAN, and they integrate easily with any ADCS.
Each wheel is mountable on its small or large face, which enables the option to mount the wheel in all axes of your satellite. The wheels can operate at a wide range of voltages between 6.5V and 16V.
Designed to be as modular as possible with shared electronics designs between all four sizes of wheels.
Each reaction wheel is individually balanced to reduce vibration. All wheels provide a mounting interface that is durable and reliable under vibration.
