SPACE / Attitude & navigation / REVIEWED 2026-09-11
Turn the satellite by changing rotor speed.
Reaction wheels change spacecraft attitude by accelerating a rotor. The purchasing unit may be a single wheel, a wheel plus separate drive electronics, or a redundant multi-wheel assembly.
These are sourcing candidates, not a confirmed Starlink supply chain.
Single wheels with digital control and selectable torque, speed and momentum command modes, offered in multiple momentum classes. [1]
Contact the manufacturer for the selected configuration and current quotation; this channel is inferred from the official product/contact page, not a stock claim.
Reaction wheels with configurable flywheels and control modes; family includes hermetically sealed options and models with optional gyro integration. [2]
Contact the manufacturer for the selected configuration and current quotation; this channel is inferred from the official product/contact page, not a stock claim.
Wheels with integrated drive electronics, magnetic shielding and optional damped pyramid mounting; manufacturer offers balancing and micro-vibration characterization. [3]
Company location: South Africa
Contact the manufacturer for the selected configuration and current quotation; this channel is inferred from the official product/contact page, not a stock claim.
Compact digitally controlled wheel family with several flywheel momentum variants and serial/I2C interfaces for small spacecraft. [4]
Contact the manufacturer for the selected configuration and current quotation; this channel is inferred from the official product/contact page, not a stock claim.
Wheel family spanning nanosatellite and larger smallsat momentum classes, with model-specific torque, mass and envelope tables. [5]
Company location: United States
Contact the manufacturer for the selected configuration and current quotation; this channel is inferred from the official product/contact page, not a stock claim.
CubeSat, SmallSat, Torque-Line and High-Line wheel ranges, including customizable performance and mechanical configurations. [6]
Contact the manufacturer for the selected configuration and current quotation; this channel is inferred from the official product/contact page, not a stock claim.
Reaction wheel units with separately specified wheel-drive electronics and several wheel variants for larger spacecraft attitude-control needs. [7]
Contact the manufacturer for the selected configuration and current quotation; this channel is inferred from the official product/contact page, not a stock claim.
Manufacturer catalog of smallsat reaction wheel assemblies; obtain the appropriate momentum class and electrical/mechanical interface documentation. [8]
Contact the manufacturer for the selected configuration and current quotation; this channel is inferred from the official product/contact page, not a stock claim.
Individual RW0 wheels and an integrated four-wheel arrangement with control electronics for small spacecraft. [9]
Contact the manufacturer for the selected configuration and current quotation; this channel is inferred from the official product/contact page, not a stock claim.
Reaction wheels with integrated motor control, offered in multiple momentum capacities. [10]
Contact the manufacturer for the selected configuration and current quotation; this channel is inferred from the official product/contact page, not a stock claim.
Compact assembly of four reaction wheels with redundant communications intended for CubeSat-class attitude control. [11]
Contact the manufacturer for the selected configuration and current quotation; this channel is inferred from the official product/contact page, not a stock claim.
A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.
Size storage against disturbances and the interval between momentum unloading events. Compare nominal and maximum limits separately.
Compare continuous and peak torque across speed and bus voltage; peak torque alone does not establish slew performance.
Check usable speed, zero-crossing behavior, torque roll-off and prohibited vibration bands.
Request exported force/torque spectra and mounting conditions; balance quality affects payload line-of-sight stability.
Compare steady-state power at a stated speed against acceleration and peak power.
Include wheel, drive electronics, brackets and damping in mass and envelope budgets.
Confirm speed/torque/current modes, telemetry timing, command protocol and redundant paths.
Ask for bearing/lubricant life evidence under the actual duty cycle and environment, plus unit-level test reports.
Specifications belong to the named product and configuration.
Datasheet identifies technical specifications as typical values that can vary between units.
Manufacturer pages and technical documents support the linked claims. A review date is not a publication date or stock check.
