Unmanned Surface Vessels (USVs) are becoming essential in modern maritime operations. They are used for surveying, monitoring, inspection, security, and research in challenging environments and without human intervention. To perform reliably, USVs need a propulsion system that is efficient, robust, and low maintenance.
Shaftless Design for Reliable USV Operation
Unlike conventional propellers, rim drive motors feature a shaftless design. By eliminating the central shaft, the risk of entanglement with ropes, debris, or fishing nets is greatly reduced. This is a major advantage for unmanned vessels operating in coastal areas, ports, and inland waterways.
Rim Drive Technology’s electric motors are designed to excel in the most demanding environments. Whether navigating through polluted waters or areas with heavy sediment and sand, these motors deliver outstanding reliability and efficiency.
Low Maintenance Electric Marine Propulsion
Maintenance is one of the biggest cost drivers for unmanned systems. By having only one rotating part, the maintenance of a rim drive is limited.
The motors can run for thousands of hours without maintenance. This makes them ideal for unmanned platforms that require long endurance and minimal servicing.
The motor is fully cast in epoxy and vacuum-potted, creating a completely sealed unit. This design prevents water ingress and ensures long-term performance.
High Maneuverability and Precise Control
USVs often require precise maneuvering and dynamic positioning. Rim drive motors offer excellent maneuverability, either as steerable POD units or in dual fixed-POD configurations with differential steering.
All motor and battery data is accessible via the motor controller, providing full system insight for autonomous navigation and remote operation. The motors support CAN-based wireless control, enabling seamless integration into modern USV control systems.
Flexible Integration for USV Designers
Every unmanned vehicle is different. That is why rim drive motors are designed with flexible cable options and easy system integration in mind. This allows naval architects, system integrators, and OEMs to adapt the propulsion system to their specific USV platform and mission requirements.
