External thruster RIM 1.5

for pontoon boatsfor ROVfor barges

The RIM 1.5 is an annular, hubless electric thruster engineered for demanding marine environments and integration on robotic and light marine platforms. Its sealed architecture and debris-tolerant design maximize operational availability for ROVs, USVs and AUVs.

Key features

• RIM-DRIVEN architecture: propeller driven at the magnetic periphery, eliminating rotating seals and oil-filled housings.
• Hubless annular motor allowing debris, algae and sediment to pass through without entanglement.
• High static thrust with optimized power-to-consumption ratio and reduced acoustic signature via a torque-prioritized speed profile.
• QuickChange™ maintenance system for rapid field removal and replacement of the propeller (Level 1 maintenance, no complex tools).
• Composite-material construction with native encapsulated stator/rotor waterproofing.
• Manufactured in France to withstand galvanic corrosion and aggressive saline environments.

Applications

• ROVs: primary thruster for observation and light work-class vehicles requiring stability and current-handling capability.
• USVs: main propulsion for surface drones (surveillance, bathymetry) focused on endurance and low power draw.
• AUVs: propulsion optimized for long-duration autonomous missions with quiet operation.
• Barges & pontoons: propulsion for service platforms and small cargo or aquaculture pontoons needing precise low-speed maneuvering.
• Defense & security: tactical vectors requiring minimal magnetic and acoustic signatures.

Details / Integration notes

• Designed as an industrial sealed annular thruster for long-duration missions where reliability is critical.
• Requires an external electronic speed controller (not included) capable of handling 30 A and Hall position sensors.
• Base and EPDM anti-vibration plate are provided to facilitate integration on various chassis.
• Availability: limited edition pre-order (series available January 2026).
