ABSTRACT:
A flywheel alternator for use with an electronic ignition system of an internal combustion engine. The flywheel has a rotor with an odd number of circumferentially located permanent magnets each of substantially the same size and shape. The radially inward pole faces of adjoining pairs of the magnets are of opposite polarity except for one pair which is of the same polarity. At least one stationary trigger coil is positioned to form magnetic circuits with the rotor magnets by bridging alternate ones of the magnets as the rotor rotates. A unique trigger pulse suitable for activating an electronic ignition system is generated only once each flywheel revolution. A stationary power coil has a length to bridge consecutive ones of the magnets to provide power to run other electrical appliances.
