The motor is integrated with the thruster without a thruster shaft, and the casing is used as the bore of stator to improve the hydrodynamic force.

The shaftless thruster is simple in structure and superior in weight, size and energy density to the existing propulsion modes.

It has a good prospect in submarines, and is an ideal choice for unmanned submarine propulsion systems. Also, it can be applied to underwater weapons such as high-performance torpedoes. At present, we are engaging the technical research and development of 800-1600 kW shaftless thrusters.

Shaftless thrusters are an efficient, energy-saving, and environmentally friendly ship propulsion system. Their advantages include energy conservation, pollution reduction, vibration reduction, and noise reduction. Shaftless thrusters will be more widely used in future energy-saving and green ships, and can bring more innovation and breakthroughs to the development of ship propulsion technology.
