CubeWheel

Small satellite reaction wheels

CubeWheel is a satellite reaction wheel that comes in small, medium and large sizes. It includes a highly balanced flywheel disc, a brushless electrical motor, an electronic driver and a microcontroller. The wheels can be given a speed reference command through I2C, UART or CAN, and they integrate easily with any ADCS.

Balanced to Perfection

Each reaction wheel is individually balanced to reduce vibration. The wheels are placed on a specialized jig that determines exactly where to remove mass, therefore ensuring that there is an even mass distribution around the rotation axis. The wheels are then balanced by drilling precision holes.

Size Matters

When it comes to satellite reaction wheels, size matters. The size of the wheel has an effect on the maximum slew rates the satellite can handle, the total momentum the wheels can store, and even the size of the vibrations and torque ripple on the satellite. That is why we offer three different sizes specifically scaled to meet the typical small satellite ADCS needs.

Tightly Integrated Electronics

One of the main objectives of CubeSats is to be as modular as possible. Parts must integrate seamlessly with one another, and connections should be simple. For this reason, each of our wheels comes with all driving and interfacing electronics integrated into a complete package.

Solid and Flexible Interfacing

It can be difficult to integrate multiple CubeSat suppliers’ components into one satellite. That is why we focus on providing a user-friendly mechanical and software interface to our CubeWheels. ​ All wheels come with coiled brass thread inserts, to provide a mounting interface that is durable and reliable under vibration. Each wheel is mountable on its small or large face, providing the option to mount the wheel in all axes of your satellite.

The wheels are fitted with a solid 14-pin screw down connector. This connector ensures a reliable electrical connection with the wheel even under mechanical stress. ​

The wheels are able to operate at a wide range of voltages. This makes the wheels compatible with satellites running on a battery voltage of anything between 6.5V and 18V.
