• 3-axis attitude control for small satellites (80–200 kg)
• Agile Earth observation and SAR platforms
• LEO constellations for telecom, IoT and broadband
• Science and technology demonstration missions

The RW180-500 family covers the upper end of Comat's Light Series. Three versions 180, 300 and 500 mNms share the same 100 × 100 × 46.7 mm envelope and the same 70 mNm torque. Integrators can change the momentum capacity late in the design without touching the mechanical interface.

High agility in a compact package. With 70 mNm of torque, the wheels support fast slews and target tracking on 80–200 kg satellites. Mass ranges from 0.800 kg (RW180) to 1.075 kg (RW500).

Plug-and-play integration. Each wheel embeds its drive electronics and connects to the onboard computer over full-duplex RS422/485 with the NSP protocol. It runs directly from a 22–32 V bus, drawing 15 W at steady state and 65 W at maximum torque.

Measured micro-vibrations. Every wheel can be delivered with its own waterfall plot, mapping micro-vibrations against speed and frequency, so AOCS teams work with measured data.

Tested to outlast the mission. The wheels are qualified to 25 g quasi-static load, 21 gRMS random vibration and 1,000 g shock. A 10-year lifetime is assessed through 200,000 zero-crossing tests under mission-representative conditions, with 60 FIT reliability and electronics rated below 20 krad.

Designed for LEO compliance. The design is demisable, in line with re-entry requirements for LEO missions and constellations.

Industrial quality. Manufactured in Toulouse, France, under EN9100. Each unit ships with a full EIDP and component traceability, with more than 30 parameters controlled during manufacturing.

The RW180-500 is built for flexibility. Customers choose between 180, 300 and 500 mNms on a common mechanical interface, so momentum can be adjusted late in the program. Further options include wheel clusters in pyramid or custom configurations, adapted mounting brackets, harness and connector adaptations, and support for integration with the customer's AOCS. Waterfall micro-vibration plots can be supplied with each unit at delivery. Contact [email protected] to discuss your requirements.
