Claims
- 1. An ignition system comprising:
- a. a flywheel having a plurality of permanent magnets with pole faces directed toward the rotational axis of the flywheel;
- b. a ferromagnetic coil disposed inside said flywheel and comprising superimposed laminations, each individual lamination having three pole legs whose ends are disposed adjacent to the rotational path of said pole faces;
- c. a charging coil disposed on the intermediate pole leg of said coil core;
- d. a trigger coil disposed on the last leg of said coil core when viewed in the direction of rotation of the flywheel;
- e. a charging circuit including said charging coil, a rectifier, a storage capacitor, and the primary winding of an ignition transformer, all connected together in a single series, said transformer having a secondary winding adapted to be connected in circuit with a spark plug;
- f. a thyristor connected by its anode and its cathode across a portion of said charging circuit including the series-connected capacitor and the primary winding; and
- g. means connecting one end of said charging coil to the anode of said thyristor, the other end of said charging coil being connected (1) through said trigger coil and a diode to the control terminal of said thyristor, and (2) through a resistor to said control terminal.
- 2. An ignition system according to claim 1 in which said coil core legs embrace over 90.degree. of the rotational path of said pole faces.
