Miniature servo drive tested successfully under extreme underwater pressure

23 January 2019

Elmo Motion Control (Elmo) 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 pressurised vessel for the servo drive.

Elmo’s experience in designing innovative and reliable servo drives for harsh environments was a key element in executing this customisation. The new solution required both R&D expertise in designing special components, as well as the know-how necessary for the implementation of a specialised production process. The modified G-TWI was tested and verified to operate without compromise at 700atm (atmospheric pressure), equivalent to -7,000 metres below sea level. Operation verification was executed at a dedicated facility lab used for testing high-pressure oil & gas technologies.
