Marotechniek Launches New E-Motor

Marotechniek, a Dutch company involved in finding new solutions for the dredging, marine, offshore and industrial sectors, has developed a new electric underwater motor, which will have its inaugural showcase during the 2015 Europort exhibition.

The unit, driven by a permanent magnet submersible motor, is especially suitable for waterborne sand mining.

The motor features built-in ‘permanent magnets’, eliminating the need to magnetize the rotor.

Elimination of reactive current reduces required amperage, leading to higher efficiency.

Overall, the pump assembly is 2-3% more efficient than traditional three-phase current sets and the unit is much more compact and lightweight, with less cabling required.

Prior to introduction, the E-motor successfully completed extensive testing on a sand dredger.
