Alternator for ignition system and auxiliary power

Claim 1

An alternator apparatus for supplying electrical power to a capacitor discharge ignition system of an internal combustion engine and for supplying electrical power to a separate power load, said alternator apparatus comprising: (A) an engine driven flywheel mounted for rotation on said engine, said flywheel including a circumferential flange; (B) a plurality of circumferentially spaced magnets mounted on the flange of said flywheel and lying in a common plane; and (C) a stator assembly mounted on said engine concentrically with said flywheel and radially inward of said flange, said stator assembly including (1) a circular magnetic core having a plurality of circumferentially spaced radial power poles lying in the plane of said magnets and at least two radial ignition poles offset from said plane, (2) power windings mounted on each of said power poles, and (3) ignition windings on each of said ignition poles, said ignition windings including a high speed winding and a low speed winding with said high speed winding having a substantially smaller number of turns of heavier wire than said low speed winding, all of said windings responding to the magnetic field created by said magnets to generate electrical outputs.
