The bow thruster integrates the stator of the propulsion motor with the duct, and the rotor of the motor with the propeller. When the rotor rotates, it drives the propeller to generate thrust. Its features include high integration, flexible power system layout, high efficiency, low vibration, and noise. It can be used in various equipment fields such as ship main propulsion, side propulsion, UUV propulsion, and torpedo propulsion.

Advantages
The seawater cooling system eliminates the need for an additional cooling system. The permanent magnet motor directly drives the propeller, removing the need for a transmission shaft system and complex mechanical structures, resulting in extremely high propulsion efficiency. The weight is significantly reduced, installation is flexible, and the installation difficulty and space requirements are greatly minimized. Vibration and noise are significantly reduced as well.
