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 water surface.
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 under 10 seconds.
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 for the control method most relevant to the 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 the vehicle.
To maximise efficiency, it is recommended to incorporate the thruster into the ROV hull profile. Alternatively, use the DISKDRIVE™ thruster with water flow guiding ducts that are available as accessories in our webshop, along with a mounting bracket and connectors. This could be built into the ROV hull profile.
Due to its unique construction and hydro-lubrication, DISKDRIVE™ is extremely durable and will outrun other thrusters over its lifetime. In the current endurance test, DISKDRIVE™ 50 thruster has been running over 6'000 hours non-stop in our testing pool. And it keeps clocking hours...
