Abstract

A magneto ignition system for battery less hand-held combustion engines includes a claw generator with a stationary circular power coil winding enclosed by two iron claw halves and with a rotating flywheel magnet ring with multiple magnetic poles. The stationary circular coil winding includes a trigger coil with a stationary coil winding arranged in a plane orthogonal to the stationary circular power coil winding. The magneto ignition system further includes an engine control module ECM for establishment of appropriate ignition timing, and an ignition coil module ICM. The stationary circular power coil winding may provide the electrical power supply to both the ignition timing module ECM and the ignition coil module ICM.
