ことにより行われる。Among the above-mentioned magnet generators, in the inner rotation type magnet generator in which the rotor rotates in opposition to the inner circumference of the stator, the stator is formed from a ring-shaped chain portion. A core having a plurality of pole portions extending inward in the radial direction is used, and a coil is wound around each of the pole portions. The winding of the coil is performed by winding a winding from the inside of the core to the pole portion.

高出力化は困難であった。In such a stator of an internal rotation type magneto-generator, since the winding is wound from a narrowly closed space inside the core in the radial direction, a nozzle type winding machine is used for winding the coil. Used. However, in the nozzle type winding machine, it is difficult to use a winding having a large wire diameter because of the strength of the nozzle. Further, since a space for the nozzle to enter is required between the coils, the area occupied by the coils on the radially inner side of the chain portion is reduced. For these reasons, it has been difficult to increase the output of the internal rotation type stator.

下するという問題がある。Japanese Patent Laid-Open Publication No. 62-138031 discloses a method for manufacturing a stator of an internal rotation type magnet generator, in which an outer peripheral core 1 and a magnetic pole core 2 are separated as shown in FIG.
After winding the coil 3 from one direction in a state where the magnetic pole core 2 is linearly linked by the insulator 4, or winding the coil 3 from the outer periphery in a state where the magnetic core 2 is linked in a ring shape,
A method of engaging the inside of the ring-shaped outer peripheral core 1 is disclosed. However, according to this method, when the coil 3 is wound, the holding member 4a made of resin or the like and the magnetic pole portion 2a corresponding to the portion facing the rotor are fixed, and the winding having a small width and a large wire diameter is wound. However, since the winding tension is about 4 to 6 kgf, there is a problem that it cannot be fixed sufficiently. It is possible to increase the width and thickness of the magnetic pole in order to fix it sufficiently, but since this part is part of the magnetic circuit, increasing the thickness lengthens the magnetic circuit and increases the magnetic resistance. However, there is a problem in that the diameter of the rotor becomes smaller and the peripheral speed of the rotor decreases and the power generation output decreases.

It is fixed to the case. According to the present embodiment, when the coil 14 is wound, the pole portions 12 extend parallel to each other with the tips 12a aligned in a straight line toward the open space, so that a sufficient space for installing the winding machine can be secured. Therefore, a flyer type winding machine can be used. Therefore, it is possible to increase the output of the magnet generator by thickening the winding of the coil 14. Further, the coil 14 is wound in a state where the gap between the pole portions 12 is wide, and then the core 10 is rolled to bring the pole portions 12 closer to each other, so that the winding of the coil 14 is easy. Since the area occupied by the coil 14 inside the portion 11 can be increased, the output of the magnet generator can be increased.

There were many things. For this reason, the strength of the bolt is unstable because a step is generated on the seat surface due to the dimensional difference from the engine case of the opposite side and an excessive stress is generated in the lower portion of the neck of the bolt. According to this embodiment, the core 10
Since the bolt mounting hole 20 is provided in the flange portion 19 of the yoke 17 into which the bolt 17 is press-fitted, the weight of the stator is reduced and the bolt seating surface becomes flat, so that stable bolt tightening strength can be obtained.

で形成してもよい。Further, in the above-mentioned first to third embodiments, the yoke is made of a steel plate which is a magnetic material in order to increase the cross-sectional area of the magnetic circuit, but the output of the magneto generator is large and the rotor is used at high rotation speed. If iron loss is a problem, the yoke may be made of a non-magnetic material.
