An Archimedes' screw serves as a rotor, inducer, impeller, and/or driver
with motor and/or generator configurations that surround the screw by
attaching to an outer cylinder of the screw. The screw acts as the motor's
rotor axis with attached permanent magnets and or frame and the stator is
built around the auxiliary circumference of this rotor. The rotor may also
house half the bearings and can be used for the movement of fluids and/or
solids, for cavitation-less drive of water vehicles, or for the generation
of electrical power when the fluids become the motive force to drive the
unit.
