Disk-Drive Thrusters

Brushless, hubless, almost partless… And not least importantly – oil-free.  The novel patented ultra-slim thruster is the future of all compact moving vehicles on and in water.


We developed an ultra-slim (15 mm thickness) rim-driven brushless thruster with integrated motor control.  The hubless propeller prevents it from getting tangled. Our patented design is pressure-proof without seals, hydro-lubricated and oil free. Its thin size makes it ideal for low-drag vertical stabilisation thrusters, as well as small vehicles where space is limited.  

The integrated motor controller uses advanced sinusoidal drive algorithms to improve efficiency and smooth operation. Precise and fast speed control enables accurate attitude control of the submarine. 

Designed for scalability

Our unique patented design allows us to use hub-less propellers that are not affected by floating debris such as pieces of water plants or ropes. 

Propellers can be exchanged quickly without special tools.  The thruster can be scaled up for more demanding thrust requirements.  The design of the thruster allows for modular installations that immediately give a user double the power without any additional development.
