Abstract
An outer-rotor type engine-operated generator is of low cost and simple construction, can be miniaturized and can leak electricity for ignition without sacrificing generator output. The engine-operated generator has a plurality of magnets arranged along an inner circumference of an outer cylindrical wall of an outer-rotor and a multipolar stator housed within the outer-rotor facing the magnets. An electricity generating section for an engine ignition device is disposed on an outside of and opposite to the outer cylindrical wall of the outer-rotor, and a through window, through which magnetic force of the magnets affects the electricity generating section, is formed in a part of the outer cylindrical wall.

An outer-rotor engine-operated generator having a plurality of magnets arranged along an inner circumference of an outer cylindrical wall of an outer-rotor and a multipolar stator housed within the outer-rotor facing the magnets, comprising:
- an electricity generating section for an engine ignition device, disposed outside of and opposite to said outer cylindrical wall of said outer-rotor;
- and
- a through window formed in a part of said outer cylindrical wall through which magnetic force of said magnets affects said electricity generating section;
- said through window comprising a plurality of slits defined in said part of the outer cylindrical wall;
- and
- each of said magnets being polarized into an outer circumferential side and an inner circumferential side, polarities of neighboring ones of said magnets are opposed to each other, and one of said slits being positioned to correspond with opposed sides of a pair of the neighboring magnets.
