Open the CIPO recordAbstract From the Canadian patent
A magneto-alternator has a plurality of alternator coils for lighting or the like and a main ignition coil for a breaker-point ignition. Stator laminations are arranged so that the ignition coil is between two alternator coils and each coil is effectively on an Eshaped core with an outer leg of each E-shaped core being shared with an adjacent coil. The flywheel has a plurality of ceramic magnets having a high potential energy so that a high alternator output is developed. The center core leg of the E core on which the ignition coil is mounted has a large air gap relative to the air gaps at the other core legs to compensate for the high energy of the magnets and thereby limit current at the …
