トするので材料費の無駄となっていた。However, in the above-mentioned prior art, it is necessary to crawl the lead wire, which is the neutral point of the stator coil, to a predetermined position. Therefore, when the stator coil is wound around the stator core, The lead wire of the stator coil for crawling has a length of 20 to 30 cm, and a winding machine that allows the length is required, so that the winding machine is necessarily large. In addition, since the extending direction of the lead wire of the stator coil after winding is not constant, it is necessary to align each lead wire in a certain direction before crawling, which is one of the causes of cost increase. There is. On the other hand, although the output line of the three-phase output line does not have to be crawled around as much as the output line of the neutral point, the output line of the neutral point is the output line due to the restrictions of the winding machine and work. It has the same length as the above, and the surplus is cut later, so the material cost is wasted.

When a field current flows through the field coil 10 through the brush 13a and the slip ring 12 and a driving force is transmitted to the pulley 5 by an engine (not shown) or the like, a rotating magnetic field is generated in the rotor core 9.

The AC output generated in the stator coil 3 flows into the diode bridge 20 via the stator coil output line 31, is full-wave rectified, and is converted into a DC output. At this time, since the output voltage of the generator changes depending on the rotation speed, the field current is appropriately turned on and off by the regulator 14, and the generated voltage is controlled to be constant.

The point terminal block 26 has a wide front opening and is electrically connected to the terminal 26a through a tapered through hole 26b. Since the terminal 26a is connected in the neutral point terminal block 26,
The lead wire 31A at the beginning of winding of the U, V, and W phases is the terminal 26.
It becomes the same potential via a and becomes the neutral point of the star connection.

いう効果もある。As described above, according to this embodiment, the neutral point of the stator coil 3 and the lead wire 31A serving as an output wire,
The winding wire 31 does not need to be crawled and fixed at a predetermined position after winding, and can be started up straight from the winding start and winding end positions, and the length of the lead wire can be greatly shortened. Further, since it is not necessary to crawl the lead wire, the winding machine itself can be downsized, and the height of the stator coil 3 can be suppressed to be low, which reduces ventilation resistance and improves cooling efficiency. Further, according to the present embodiment, conventionally, the neutral point connection is such that the lead wire of the crawled stator coil 3 is once straightened and then the tip thereof is twisted for solder connection. It is sufficient to connect the lead wire 31A at the beginning of winding of the stator coil 3 to the terminal 26 of the neutral point terminal block 26, which simplifies the work and reduces the cost. On the other hand, since the output line 31 of the stator coil is connected to the terminal 24 of the diode terminal block 25 through the through hole 26a of the neutral point terminal block, the output line 31 of the stator coil is not connected to the diode terminal block 25. There is also an effect that it is properly positioned, protected against other potentials, and environmentally superior.

Since the neutral point can be connected by connecting it to the terminal, the winding equipment can be downsized, the work can be simplified, and the man-hours can be reduced, thereby significantly reducing the cost. Further, since the lead wire serving as the output wire of the stator coil is connected to the diode terminal block through the through hole of the neutral point terminal block, it is positioned with respect to the diode terminal block and is environmentally friendly.
