Abstract
A magneto generator for an engine having a flywheel, in which the flywheel comprises a rotor mounted for axial rotation and has a rim of magnetically permeable material. A magnetically permeable core has first and second ends located adjacent to the rim at circumferentially spaced points. At least two wire coils are wrapped on the core. The rim defines a permeability path between the ends of the core. A fixed magnet is placed on one end of the core. The rim is interrupted at circumferentially spaced points to provide walls and windows alternately making and breaking the permeability path when the rotor is rotated to produce voltage pulses in sinusoidal form in the coils. The positive half cycles in one of the coils is used to charge an ignition storage capacitor for energizing a spark plug. The negative half cycles in the other winding are used to charge a battery.
