If an autonomous deep-sea experiment requires a mechanical drive to carry out any task involving movement or the expulsion of force, then a reliable and powerful drive engine is needed – and it has to be one that works even in a high-pressure environment.

The majority of drives available on the market today are designed for one very specific purpose and cannot be used for a diverse set of tasks. KUMOs compact and lightweight Drive Unit is, by comparison, highly customisable to meet a variety of customer requirements.

The power supply, housing material, torque, revolutions, shaft ends and connectors can all be designed, manufactured and tested to meet specific requirements. Furthermore, all Drive Units are comprehensively tested for functionality and strength in KUMOs own pressure tank prior to delivery.

The Drive Unit can provide an enormous torque of up to 15 Nm and its turning is counted in steps of 15 degrees by its internal electronics. Additionally, shaft positioning can be achieved with a precision of 1/16 revolutions attributed to the internal electronic system.
