Abstract
A submersible electric propulsion motor includes a sealed cylindrical stator housing defining a central flow passage and a cylindrical rotor core disposed within the stator housing passage such that the stator housing encompasses the rotor core. The rotor core defines a center flow opening which communicates with inlet and outlet ends of the stator housing passage. The motor also includes a propulsion propeller having a plurality of radial blades and a central cylindrical hub. The propeller is disposed within and across the rotor core opening with its periphery being rigidly connected to the rotor core. A support structure has end portions disposed at and rigidly attached to the stator housing inlet and outlet ends, and an axial portion which extends axially through the stator housing passage and rotor core opening and is rigidly attached to the radial portions. A cylindrical bearing is disposed about the support structure axial portion within the rotor core opening between the axial portion and the propeller hub and mounts the propeller and rotor core rigidly attached thereto for rotation relative to the support structure and the stator housing. Electrical power cables emanate from the stator housing through the support structure end and axial portions to the motor exterior for connection to a source of electrical power.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
