Abstract
An engine ignition and charging system employs magnets mounted on a rotor, and a stator positioned relative to the rotor such that charge coils, alternator coils, and a power coil on the stator are located such that the magnets pass in close proximity thereto as the rotor rotates. The rotor also has a magnetic timing means for generating a timing flux path at a predetermined location relative to the rotor. A Hall effect transducer circuit is positioned in proximity to the rotor such that as the flux path passes, the flux path is sensed so as to generate a timing trigger voltage. This trigger voltage is employed in conjunction with an ignition voltage generating circuit to supply an ignition voltage to a spark plug in timed sequence with rotation of the rotor. The power coil on the stator supplies power to the Hall effect transducer for operation thereof. A charging circuit connects an output of the alternator coils to a system battery for charging thereof. With the disclosed system, timing pulses are provided which are substantially independent of engine RPM.
