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.
