About
The RW400 is a medium-class reaction wheel from AAC Hyperion designed for 3U to 16U CubeSats and small satellites requiring more angular momentum storage than the RW222 can provide. It provides fine-pointing capability for Earth observation, scientific, and technology demonstration missions. The brushless DC motor design ensures long operational life, and multiple units can be configured for full 3-axis or 4-wheel pyramidal control.
