A flywheel magneto generator which comprises a rotor having a magnet attached to an outer circumferential side of a flywheel and a stator constructed by winding a generating coil around a core having a magnetic pole portion opposed to a magnetic pole of the rotor, wherein a through hole is formed in a peripheral wall portion of the flywheel, a yoke plate is provided so as to block one end of the through hole which is opened on an inner circumferential side of a peripheral wall portion of the flywheel, the magnet to which a magnet cover is attached is supported on the yoke plate, and one magnetic pole face of the magnet is opposed to the yoke plate.

Flywheel magneto generator

A generator apparatus driven by an internal combustion engine and comprising a revolution controller to control a revolution of the internal combustion engine so as to maintain a desired value of a terminal voltage of a battery which is charged by an output of an AC generator driven by the internal combustion engine while controlling an actuator for operating a fuel supply adjuster, an engine start controller to give a start instruction from a timer circuit to start means when the battery is discharged until the terminal voltage is lowered to a set value and an engine stop controller to give a stop instruction from the timer circuit to stop means when the battery is perfectly charged by the operation of the engine until the revolution of the engine is lowered to a stop revolution thereof whereby the starting and stopping operations of the engine are controlled without undercharging and overcharging the battery.

Generator apparatus driven by an internal combustion engine with start and stop controllers

A discharge lamp lighting device driven by an internal combustion engine is disclosed which is capable of lighting a discharge lamp without using a ballast constituted by a leakage transformer. The device includes a generator which is driven by the internal combustion engine and of which output characteristics exhibit drooping characteristics, so that an output voltage of the generator may be applied to a discharge lamp without using any ballast. Output characteristics of the generator are so set that an output voltage of the generator at a non-load state thereof may be higher than a break-down voltage of the discharge lamp, a shortcircuit current of the generator may have a level sufficient to restrict a discharge current of the discharge lamp just after starting of discharge thereof to an allowable level or below, and a voltage across the discharge lamp and a discharge current thereof at a steady state thereof each are kept within a rated range.
