CubeMars DW15 48V 750W Underwater Thruster, 15kgf Thrust, 350M Depth, Aluminum Alloy for ROVs & USVs

Overview

The CubeMars DW15 Underwater Thruster delivers reliable, efficient propulsion for unmanned surface vehicles (USVs), remotely operated vehicles (ROVs), and electric surfboards. Engineered with 48V rated voltage, 750W power output, and a maximum mooring thrust of 15 kgf, it operates at depths up to 350 meters. The aluminum alloy precision-cast shell and propeller ensure high strength, corrosion resistance, and long service life, while the low-resistance dynamic seal and two-stage sealing chamber provide superior water ingress protection. Its POM nozzle, 28-pole motor rotor, and 106 mm propeller enhance propulsion efficiency, and the integrated thermal conductive filling supports effective water-cooled heat dissipation.

Key Features

• High Performance 48V, 750W, 15 kgf maximum mooring thrust.

• Deep-Water Capability Operates reliably at 0350 m depth.
