Motor and gearbox combination for sub-sea use

Pressure compensators from maxon provide sub-sea ROV operators with abilities to perform operations at extreme depths.

A range of pressure compensators for Remote Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs) has been released by maxon Aquatic Solutons. The compensators are configured to operate to depths to 6,000m and are highly efficient and reliable.

maxon has existing thruster products and saw an increase in enquiries for subsea pressure compensated actuators. With customers asking for thrusters without propellers, the company developed a range for their needs.

One such customer contacted maxon for a subsea inspection application. The units were driving sensors for the monitoring of corrosion on the various types of subsea structure. From the detailed specification, a motor and gearbox combination were derived to deliver the output requirements from the input supply. Then it was over to the design engineers to package them into the oil filled housing and to detail the other modifications that the customer had requested. The result was a top-level drawing that was sent to the customer for approval.

Many industries are moving away from hydraulic actuation towards electro-mechanical actuation. maxon offers both rotary and linear actuation methods for the subsea arena. Rotary could be motor only for high speed low torque applications or motor gearbox for lower speed higher torque applications. By using the maxon screw drive products, it is possible to supply linear actuators to suit a variety of speed and load applications, such as grippers, manipulators, fin actuation and propulsion.

maxon has a long history of supplying motors and drive systems for extremely hostile environments, including underground, marine and space applications. These environments provide a wide range of different challenges including shock and vibration, high temperature, low temperature and vacuums.

To this end, maxon has invested in a large suite of test equipment to validate products to these challenging conditions.
