Abstract:
An inductor alternator flywheel system comprising:a rotatable member mounted on bearings for rotation about an axis, said member including a flywheel rotor with a hollow center and an inwardly facing radial surface forming a plurality of protrusions extending radially inwardly, said radial protrusions being circumferentially spaced apart with spaces between said protrusions free of magnetic material; a non-rotating member having a source of homopolar flux, said flux creating magnetic poles in said protrusions; at least one cylinder having an outer radial surface, said cylinder being mounted concentric with respect to said rotor and spaced apart radially from said protrusions such that an armature air gap is formed between said protrusions and said outer surface, said cylinder being constructed of substantially high permeability material; and at least one armature coil mounted in an air-core armature within said air gap such that said flux induces an alternating voltage in said armature coil when said rotor rotates about said axis.
