Abstract:
A submersible electric thruster operable to propel underwater vehicles, surface vehicles, amphibious vehicles, etc. The submersible electric thruster includes a stator assembly having a base, stator, windings, and bearings and an external rotor assembly having a cylindrical arrangement of permanent magnets with a hub that is secured to a shaft. The stator forms the center of the motor and the permanent magnets spin around the stator. A propeller hub is integrally connected to the rotor assembly with angularly spaced propeller blades extending radially from the propeller hub. An annular nozzle surrounds the propeller and motor, forming an inlet and outlet for water flow. A nose cone is connected to the stator assembly and a tail cone is integrally connected to the nozzle assembly. Supporting arms may extend from the stator assembly to support the nozzle and/or supporting arms may extend from the nozzle to the support the tail cone.

Claim (Index 1):
A submersible electric thruster comprising:\n a stator assembly having a stator and electrical windings; a rotor assembly having a plurality of magnets arranged radially outwardly of the electrical windings and configured to rotate about the electrical windings when driven by electromagnetic forces provided by the stator and electrical windings; a propeller with a hub co-rotatably connected to the rotor assembly, the propeller having at least one propeller blade extending from the hub; an internal chamber that contains the stator and electrical windings; wherein the thruster is configured to allow at least the internal chamber to be flooded with water when the thruster is submerged; and a protective barrier that encapsulates the stator and electrical windings without enclosing any air cavities, the protective barrier being configured to make direct contact with the flooded water to thereby prevent the flooded water from contacting the stator and electrical windings when the thruster is submerged.
