Claim:
1. A PPPEM comprising: a stator internally mounted on a stator output shaft and disposed on a stator axis collinear with a central axis of said PPPEM, said stator being integrally formed with an external stator gear; a series of push-pull electromagnets for generating push-pull radial magnetic forces disposed radially around said stator axis defining a stator centerline; a planetary rotor having a rotor axis eccentric to said stator axis and comprising an external, rotatably mounted, rotor ring formed integrally with a rotor ring-gear; and a step-gear integrally formed with said planetary gear, said step-gear being axially aligned with said stator centerline and in planetary mesh contact with an eccentric output ring-gear, such that when said PPPEM is operated, said step-gear acts as a reducer, being disposed coaxially with said stator so as to provide a high gear-ratio directly to said output ring-gear by eliminating the eccentricity between said stator axis and said rotor axis, wherein when said series of push-pull electromagnets is sequentially activated, said rotor ring is impelled by said push-pull radial magnetic forces to roll about a continuous series of moving tangential contact lines formed by the temporary, sequential, mesh contacts between said rotor ring-gear and said stator gear, such that said planetary rotor advances around the outer circumference of said internally mounted stator in a continuous rolling motion providing a source of power output from said PPPEM.
