Elmo’s Miniature Servo Drive Tested Successfully under Extreme Underwater Pressure

Jan. 25, 2019
The ultra-small, already rugged by nature Gold Twitter servo drive was modified to match the needs of deep underwater applications, having to withstand high pressures up to 700atm.

Elmo Motion Control (Elmo), a leading provider of advanced motion solutions, announces unique solution for typical underwater applications such as Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs), which don’t always allow for a fully controlled pressurized vessel for the servo drive.

Elmo’s vast experience in designing innovative and reliable servo drives for harsh environments was a key element in executing this customization. The new solution required both R&D expertise in designing special components, as well as the know-how necessary for the implementation of a specialized production process. The modified G-TWI was tested and verified to operate without compromise at 700atm (atmospheric pressure), equivalent to -7000 meters below sea level. Operation verification was executed at a dedicated facility lab used for testing high-pressure oil & gas technologies.
