CS-thruster is designed with compatibil- ity in mind. For example, the number of windings in the stator can be adjusted in the production stage, so that the thrust- ers can adapt to a supply voltage level between 24-800 VDC. This allows the system to be incorporated with a wide range of power sources. In addition, the motor controller is a commercially available shelf product, ensuring high compatibility with custom electronics.

Lastly, thrusters can be incorporated as a propulsion system for both remotely op- erated vehicles (ROVs), autonomous un- derwater vehicles (AUVs), and manned submersible vehicles.

Secondly, the CS thrusters are engi- neered for reliability in harsh environ- ments. Rim-driven thrusters have a built-in cooling mechanism, where the surrounding water is used as a cooling medium. However, in the case where high temperatures should arise, the CS -thrusters temperature measurement is incorporated in the design. Further- more, the thrusters which integrate high torque and a robust stator contrib- ute signi? cantly to their stability and reliability, even under strenuous opera- tional conditions. www.marinetechnologynews.com 15
