Patent ID: 8084909

Claim:
A motor/generator machine for producing motor forces or generating electrical power comprising: a field source of a cylindrical configuration having an array of coupled permanent magnet segments, said field source having a first longitudinal axis that is aligned along the center axis of the said cylindrical field source, said field source configured with magnetization directions chosen to produce a multi-pole internal magnetic field that is internal to the array of coupled permanent magnet segments and transversely disposed in a first direction from said longitudinal axis and said internal magnetic field having a return flux that is exterior to said field source and an internal armature having a plurality of multi-phase coils of the same order multi-pole as said field source; said internal armature of a cylindrical configuration having a second longitudinal axis that is parallel to the first longitudinal axis, said internal armature being placed within said field source such that there is a radial spacing distance between an exterior surface of the internal armature and an internal surface of the field source, said internal armature having at least one coil that links with the internal flux created by the field source; an external armature of a cylindrical configuration having a third longitudinal axis that is parallel to the first longitudinal axis, said external armature being placed outside said field source such that there is a radial spacing distance between the interior surface of the external armature and the exterior surface of the field source, said external armature having at least one coil that links with said external return flux created by the field source and said external armature having a plurality of multi-phase coils of the same order multi-pole as said field source, and said internal and external armatures are coupled together so to form a unified armature assembly.
