CubeMars DW15

The DW15 is a high-performance underwater thruster developed for ROVs and AUVs working in deep water. At a rated 48 V and 750 W of continuous power it produces at least 15 kgf of static thrust and is rated to 350 meters. The SW12 shares the same Ø130.6 mm housing diameter but is limited to 30 meters, while the DW15 suits deep water missions such as inspection, survey and sensor deployment.

Key features

• Sealing for deep water. Two independent sealed chambers and a low-friction dynamic shaft seal keep sand, silt and seawater out of the motor chamber under high water pressure.
• Thrust for medium and large vehicles. At least 15 kgf of static thrust is sized to meet the propulsion needs of medium to large ROV and AUV platforms.
• Continuous full-load operation. High thermal conductivity potting and cooling by the surrounding water let the thruster run at full load without overheating.
• Large propeller. A Ø106 mm aluminum alloy propeller turns inside a POM nozzle. The streamlined nozzle reduces drag under water.
• Easy integration. It comes with a 1.5 m, Ø8 mm TPU-jacketed 3 x 16 AWG cable. The driver (ESC) is external.

Applications

Typical applications include underwater inspection and survey vehicles, sensor-carrying AUVs, medium and large ROVs, unmanned surface vehicles (USVs) and electric surfboards.

Is it enough for your project?

A single DW15 delivers at least 15 kgf of static thrust. For example, a vehicle with two DW15 units on the horizontal axis reaches at least 30 kgf of forward static thrust. Vehicle speed also depends on hull drag and tether load, so thrust needs should be worked out together with the vehicle's drag.

The housing measures Ø130.6 x 174.5 mm and weighs 1260 g, about 735 g in water. The motor rotor has 28 poles. Operating temperature is 0 °C to 40 °C. If you need more thrust, consider the DW20, and for a smaller housing, the DW10.

How it compares to similar models

• SW12. Same 48 V and Ø130.6 mm diameter, 12 kgf of thrust and 520 W of power. It weighs 1180 g and works down to 30 m.
• DW10. 540 W at 36 V and at least 10 kgf of thrust. With a Ø100 x 148 mm housing and 840 g it is more compact.
• DW20. 910 W and at least 20 kgf of thrust. With a Ø152 mm housing and 1630 g it is larger, and it pairs with the TW-80A-12S ESC.

Frequently asked questions

Which ESC does it work with?

The DW15 runs with an external driver. The pairing CubeMars recommends is the TW-40A-12S underwater ESC, which is also compatible with the SW7, SW12 and DW10.

Can it be used in seawater?

Yes. The aluminum alloy housing resists corrosion and the sealing design keeps seawater and sediment out. The manufacturer recommends rinsing with clean water after each use.

Why choose the DW15 over the SW12?

If your vehicle will go deeper than 30 meters, the SW12 is not enough. The DW15 works down to 350 meters and gives 3 kgf more static thrust.

Are mounting parts included?

Yes. The box contains two mounting bases, a connecting rod and screws in three sizes. CubeMars also publishes a 3D drawing of a shared mounting bracket for the SW12, DW15 and SW17.
