Abstract
A magnetic ignition system for an internal combustion engine has a magnet wheel revolving with the crankshaft of the engine. At least one permanent magnet rotates with the magnet wheel. A stationary armature with a coil is provided. The permanent magnet induces a voltage in the coil, and the voltage is supplied to an energy storage. The magnet wheel has a magnet support made of a magnetically conducting material. A section of the magnet support that is in magnetic shunt is magnetically saturated.
