Aluminum alloy ring shaped rotor with inlaid radial and lateral permanent magnets turns concentric to a three piece complementary ring shaped stator having one radial and-two lateral electromagnet windings to provide a brush less variable speed electric motor-generator designed for a particular power rating and to provide a virtual electromagnetic bearing in the "ON" mode of operation. Two radially and laterally supporting roller bearings interfacing the rotor and stator aluminum alloy castings to provide support of the rotor in the "OFF" mode of operation. A "U" ring shaped molded tow part casting with reinforcing heat sink like struts is press fitted over the ring shaped motor-generator assembly, which has two lateral phalanges to provide an air and watertight assembly specifically adapted to the particular application. Two sealing ring cavities in the inner walls of the outer casting on each side and the ring shaped rotor are interfaced by a lubricated compression sealing ring. Inward pointing propeller blades are optionally an integral part of the rotor's molding process, or by separate and bolted-on to the inner surface of the rotor's rim. A watertight junction box for external electric connections is assembled over the shielding cover. Inline-pipeline electric motor- generator propellers can be specifically adapted to numerous applications for propulsion or the harnessing of energy including: air, water, oil and gas pipelines, the powering of vessels and the harnessing of ducted air, steam, river rapids, tidal, wave power and the like directly to electricity.
