Abstract

Electric rotating machines and/or assembly which, dependent upon the specific embodiments utilized may be in the form of a motor, generator or combination of both wherein a common stator assembly is disposed in an operative position relative to at least one but in some embodiments a plurality of rotor assemblies preferably having annular configuration and further being defined by a central opening in which the stator assembly is mounted. The supporting structure has the stator assembly fixedly attached thereto as well as the one or more rotor assemblies moveably mounted thereon in rotational travel relative to the stator assembly and, dependent upon the embodiments, relative to one another when a plurality of rotor assemblies are utilized. One feature of the overall structure is an increase in versatility and applicability for specific practical application by eliminating the use, need or requirement of a central support shaft commonly found in prior motors/generators. One or more power takeoff assemblies may be connected in driven relation to one or more rotor assemblies and may further be disposed exteriorly of both the one or more rotor assemblies and the stator assembly.
