DISKDRIVE™ THRUSTERS

Brushless, hub-less, almost part-less… And fundamentally – oil-free.

Hydromea’s ultra-slim, rim-driven DiskDrive thruster is the future of propulsion for compact vehicles, both underwater and on the surface.

Design

DiskDrive™ is a patented, ultra-slim, rim-driven brushless thruster with a thickness of just 15mm. The thin size makes it ideal for low-drag vertical stabilisation thruster applications, as well use on small vehicles where space is limited.

The hub-less propeller prevents it from becoming tangled – the thruster will easily navigate through floating debris such as water plants or ropes. Our patented design contains no seals, it is pressure-proof, hydro-lubricated and oil free.

The simple design allows the user to exchange propellers quickly and without any special tools in just 10 seconds.

Operation

The DiskDrive™ is extremely simple to use and compatible with a range of commercially available electronic speed controllers (ESCs). The three-phase sensorless brushless motor architecture allows you to choose the control method most relevant to your application.

The suggested operational voltage is 16V – providing 30N of thrust. This can be adjusted for higher thrust applications, or lower power attitude control of your submarine. The design of the thruster allows for modular installations that can immediately provide a user with double the power without any additional development.

To maximise efficiency it is recommended to use the DiskDrive thruster series with water flow guiding ducts. This could be built into the ROV hull profile. Alternatively, ducts are available as accessories, along with a mounting bracket and connectors.

F A Q

Any sensor-less electronic motor controller (EMC) with the right voltage/current rating should be suitable.

The propeller ring can be easily replaced without tools within a few seconds. By pushing against the blades very close to where they are attached to the ring, the two magnet rings can be pushed apart. The propeller ring can then be replaced. Detailed instructions with pictures for a propeller change can be found in the manual.
