Magnetoelectric generator and method for manufacture thereof

1. A magnetoelectric generator comprising:

a bowl-shaped flywheel;

a plurality of permanent magnets that are fixed to an inner circumferential wall surface of said flywheel so as to be arranged circumferentially;

a stator core that is disposed radially inside said flywheel and that has an outer circumferential surface that faces said permanent magnets;

a generating coil that is constituted by:

a generating coil main body in which a conducting wire is wound onto respective teeth that are formed on an outer circumferential portion of said stator core so as to project radially outward in a radial pattern; and

an output wire that is led axially outward from said generating coil main body; and

a fixing material that is applied to a surface of said generating coil and heat-hardened;

wherein an insulating insert is inserted into a gap in said generating coil between adjacent teeth; and

said output wire is fixed to said generating coil main body by said fixing material and is also fixed by being held between said insulating insert and said generating coil main body.

2. A magnetoelectric generator according to claim 1 , wherein said insulating insert has a wedge shape that tapers axially inward.

3. A magnetoelectric generator according to claim 1 , wherein a close-contact surface that has a shape that matches a cross-sectional shape of said output wire is formed on said insulating insert.

4. A magnetoelectric generator according to claim 1 , wherein said insulating insert is constituted by:

an inserted portion that extends axially inward; and

a close-contact portion that is bent circumferentially from said inserted portion and that has a close-contact surface that has a shape that matches a cross-sectional shape of said output wire.

5. A magnetoelectric generator according to claim 1 , wherein said insulating insert is constituted by an elastic resin.

6. A method for manufacturing a magnetoelectric generator according to claim 1 ,

wherein said method for manufacturing a magnetoelectric generator includes steps of:

winding said conducting wire onto each of said teeth;

fixing said output wire of respective phases so as to be held between said insulating insert and said generating coil main body by inserting said insulating insert into said gap;

applying said fixing material to said generating coil main body and said output wire; and

simultaneously fixing together adjacent conducting wire of said generating coil main body and fixing said output wire to said generating coil main body by heat-hardening said fixing material.

7. A method for manufacturing a magnetoelectric generator according to claim 6 , wherein said fixing material is applied to said generating coil main body and said output wire after said output wire that is led out from said generating coil main body is bent circumferentially toward output lead wires that are connected to electrical equipment.
