About
Collins Aerospace’s Teldix space wheels are high motor torque momentum and reaction wheels that can be chosen with integrated wheel drive electronics, offering angular momentum storage capacities ranging from 0.04 to 68 Nms. These wheels are designed to accommodate the attitude control system requirements for spacecraft weighing between 30 kg and 7,000 kg. The product line boasts more than 40 years of experience in space wheel technology and over 7,300 years of combined in-orbit operational time. Key features include optimization for power/loss torque and volume/mass, hermetically sealed construction, and a modular configuration allowing for fast adaptation to customer requirements. The wheels incorporate space-qualified subsystems, including the rotor, motor, bearing unit, and electronics. They are available in a broad spectrum of types, suitable for satellites weighing 1,500 to 5,000 kg, and are designed for high reliability through heritage, with a lifetime design exceeding 15 years. They can be used interchangeably as momentum or reaction wheels.
