About
The RSI 4-75/60 is the smallest wheel in Collins Aerospace’s TELDIX space wheel family, delivering angular momentum storage in the sub-4 Nms range with fully integrated Wheel Drive Electronics (WDE). It provides attitude control and momentum/reaction wheel functionality for small spacecraft starting around 30 kg, and shares the same hermetic sealing, modular configuration, and power/loss-torque optimization design philosophy as the rest of the TELDIX line, which has accumulated more than 40 years of product heritage and 7,300+ cumulative years of in-orbit operation across the wheel family. It is currently in production and flight-proven.
