Abstract
A stator core includes: a laminated body in which a plurality of intermediate plates that have dowels are laminated so as to be integrated by dowel crimping between layers; and a pair of end plates that are disposed so as to be positioned on opposite sides of two end surfaces of the laminated body, and a receiving aperture that extends parallel to an axis of rotation is formed on the laminated body, a bent portion is disposed on the end plates, and the end plates are joined to the laminated body by engaging the bent portion in the receiving aperture.
Claims7
A magnetoelectric generator comprising:
- a bowl-shaped flywheel that rotates around an axis of rotation;
- a plurality of permanent magnets that are fixed to an inner wall surface of said flywheel and that rotate together with said flywheel;
- a stator core that is disposed radially inside said permanent magnets, that comprises an annulus portion and a plurality of teeth that project radially outward from said annulus portion, and that also has an insulating film formed on a surface;
- and
- a generating coil that is configured by winding conducting wire onto said teeth,
- said stator core comprising:
- a laminated body in which a plurality of intermediate plates that have dowels are laminated so as to be integrated by dowel crimping between layers;
- and
- a pair of end plates that are disposed so as to be positioned on opposite sides of two end surfaces of said laminated body,
- wherein a receiving aperture that extends parallel to said axis of rotation is formed on said laminated body, an engaging portion is disposed on said end plates, and said end plates are joined to said laminated body by engaging said engaging portion in said receiving aperture.
