In 2014, Marotechniek developed an innovative new electric underwater motor based on Permanent Magnet Technology. This motor features built-in “Permanent Magnets,” eliminating the need to magnetize the rotor. The elimination of reactive current reduces the required amperage, leading to higher efficiency. Overall, this motor is 4-6% more efficient than the traditional short-circuit anchor motor and is much more compact and lighter in weight. As of 2015, approximately 30 units are now in successful operation.
Below is an overview of the product range of Marotechniek’s underwater and specialty motors.
