Abstract:
1. A magneto generator comprising: a flywheel having a cylindrical portion and being rotatable about an axis of rotation; a plurality of magnets mounted on an inner peripheral surface of said flywheel so as to rotate therewith; a stator core having a plurality of teeth protruded outwardly in a diametral direction and being disposed in opposition to said magnets; and magneto coils with conductive wires wound around said teeth; wherein said stator core has a laminated core formed of a plurality of magnetic sheet steel plates laminated one over another, and a pair of end plates disposed so as to sandwich opposite side surfaces of said laminated core, and at least one of said pair of end plates is made of a metallic material whose heat radiation is higher than that of said magnetic sheet steel plates, wherein: said metallic material has a tensile strength higher than that of said steel sheet plates; and at least one of said end plates among said teeth of said stator core has a circumferential width in a rotational direction around said axis of rotation smaller than a circumferential width of said laminated core.
