Submersible Outboard Electric Motor/Propulsor

摘要

Mr. Taylor has more than 18 years of experience in the field of research and development engineering. Since joining Westinghouse in 1974 he has been involved in the design and development of advanced electrical machinery including large, high power density motors for electric drive ship propulsion, pulsed homopolar generators for electromagnetic launchers, high current density contacts for switching applications, research in automated manufacturing, and robotic system development. He is currently managing a section that deals with rotating power equipment for military applications, with emphasis on thermal and electromagnetic modeling. ABSTRACT A demonstration submersible outboard electric motor/ propulsor has been designed, built, and successfully tested. This concept involves mounting a propeller directly inside a rotor of a specially designed induction motor. This motor/ propulsor has the advantages of direct seawater cooling and bearing lubrication, direct drive, shrouded propeller, variable positioning, easy access, and high maneuverability. The motor/propulsor is readily adaptable to dual, independently‐controlled and contra‐rotating propellers without the need for gears. The concept has been investigated conceptually for application to primary propulsion, secondary propulsion, and pod drives, for amphibious, surface, and undersea vehicles.
