Abstract
In order to increase the power output of a magneto generator without causing additional undesired sparks to be generated in the ignition system, a plurality of permanent magnets each having associated pole pieces is arranged around the periphery of a magnet wheel. The ignition armature and at least one additional armature are fixedly mounted so that, during rotation of the wheel, the pole pieces interact with the legs of an E-shaped core in each of the armatures. However, the polarity of the permanent magnets is such that only the first of these magnets causes the generation of a spark in the ignition system. The polarity of the additional permanent magnets is such that no spark is induced when they pass by the ignition armature during rotation of the wheel. Since all three magnets, regardless of the polarity, are active in inducing AC voltages in the auxiliary armature windings, the power output of the latter is increased.
