RW-1Nms is a reaction wheel for imaging satellites requiring platform stability and precise attitude control.

RW-1Nms is Dragonfly Aerospace's reaction wheel for imaging satellites that require platform stability, precise control, and minimized disturbance torques.[1]

The product is ITAR-free and TRL 9, and Dragonfly's components overview also lists the component family as ITAR-free and TRL 9.[1][2]

It provides 1.0 Nms angular momentum at 28.5 V and has a speed range of +/-10000 RPM.[1]

The listed torque is +/-39 mNm, with a +/-74 mNm value marked for Version 2.[1]

Control modes are current, speed, and torque, with speed and torque control rates of 10 Hz.[1]

Imaging-mode steady-state speed error is listed below 0.5 RPM, and steady-state torque-control momentum error is listed below 5.09e-5 Nms.[1]

Interfaces are CAN and RS485, supply voltage is 12 to 36 V, power at 0.1 Nms is approximately 1.2 W, and peak power is 108 W.[1]

The operating temperature range is -20 C to +60 C, dimensions are 102.8 x 100 x 50 mm for Version 2, and mass is 1.0 kg.[1]

Environmental and reliability features include 14.14 g RMS vibration under GEVS, component-level radiation tolerance above 20 kRad, ABEC 7 bearings, over-temperature and current protection, latch-up protection, regenerative braking, and control timing knowledge below 1 ms.[1]
