Disclosed herein is an apparatus of a contra rotating generator. The
contra rotating generator comprises a cylindrical armature supported on
an inner shaft. The inner shaft rotates in a first direction. A
cylindrical magnetic field rotor is supported on an outer shaft. The
outer shaft is oriented coaxially to the inner shaft. The outer shaft
contra rotates opposite to the first direction. A plurality of cam
followers maintains uniform air gap between outer surface of the
cylindrical armature and inner surface of the cylindrical magnetic field
rotor. The uniform air gap prevents mechanical contact between the
cylindrical armature and the cylindrical magnetic field rotor. A sprag
clutch prevents unidirectional rotation of the inner shaft and the outer
shaft. The contra rotation between the cylindrical armature and the
cylindrical magnetic field rotor increases relative magnetic flux speed
for generating electrical power at low speeds of operation.
