Abstract

A magneto generator for a motorcycle engine having a flywheel, in which a plurality of magnets are circumferentially arranged at equal intervals, a certain number of adjacent magnets have the same polarity at their inner surfaces, and N- and S-pole alternately appear at the inner surfaces of the remaining magnets. A stator arranged within the flywheel includes one large pole core and a plurality of small pole cores, each of which extends radially outwardly to face to the inner surfaces of the magnets at their T-shaped pole pieces formed at their forward ends. A capacitor charging coil is wound on the large pole core so that a single pair of positive and negative halfwave voltages are generated at the coil to perform a single spark ignition for each revolution of the magneto generator.
