The output winding is wound in the #3 slot to #8 slot and the #13 slot to #18 slot,
Auxiliary windings are wound in #19, 20, 1, and 2 slots and #9 slot to #12 slot.

つて各スロツトはＹ軸に対称となつている。 #3 slot to #8 where the output winding is wound
The slot arrangement of the slot and #13 slot to #18 slot is formed as follows. That is, when the X and Y axes are introduced with the center O of the armature core 1 as the origin as shown in FIG. The #15 slot is provided at the position that is the opening center line of the #15 slot across the center O of the armature core 1, and the center line B of the tooth located between the #5 slot and the #6 slot is center O
The #16 slot is located at the center line of the opening of the #16 slot, which is separated by the #16 slot. In other words, the angle AOB
= 1 pitch (15°) and the angle XOB = 1/4 pitch (3.75°). The formation positions of the other slots around which the output winding is wound are the same, and the positions where the opening center line of the slot and the tooth center line coincide at the symmetrical position of the magnetic poles forming a pair. There are slots for each. Each slot is therefore symmetrical about the Y axis.

要部説明図であり、第５図のものとステータ２の
スロツト位置だけが異なる。 FIG. 2 is an explanatory view of the main parts of the engine-driven generator according to the present invention, and differs from that in FIG. 5 only in the slot position of the stator 2.

場合と実質的に同等の効果が生じる。 Since they are formed symmetrically to the magnetic poles 6 and 7 of the rotor 5, when the rotor 5 is rotating within the stator 2, for example, the edge portions 6-1 and 6-2 of the magnetic poles 6 are at the opening position of the slot. Sometimes, the edge portions 7-1 and 7-2 of the other magnetic poles 7 are located at the teeth between the slots, and the magnetic flux easily passes between them, and when the stator 2 is skewed, it is substantially different. has the same effect.

固定される。 When the output winding 3 and the auxiliary winding 4 are toroidally wound on the stator 2 using an automatic winding machine, the stator 2 is divided into two parts, that is, the armature core is divided into two parts along the Y axis in FIG. Winding is performed in a laminated state. Then, the stator end faces are brought into alignment and aligned, and the stator 2 is fixed to the end portion 12 on the engine side with bolts 9 as shown in FIG.

ド部１２に固定する。 FIG. 4 shows a partial explanatory diagram of another embodiment of the assembly of the auxiliary winding, in which grooves 21 are provided at each end of the stator 2-1, which is divided into two parts. After the output winding 3 is wound around the stator 2-1, which is divided into two parts, using an automatic winding machine, the auxiliary winding 4 is wound around the bobbin.
into the groove 21. In this way, the output winding 3
and two stators 2- around which auxiliary windings 4 are wound.

なお出力巻線３の巻線はいわゆるトロイダル巻
について述べたが、一般的な巻線である重ね巻、
波巻等の巻線であつても同様にスロツト・リツプ
ルが小さくなることは言うまでもない。 Although we have described the so-called toroidal winding of the output winding 3, there are also general windings such as lap winding,
It goes without saying that the slot ripple is similarly reduced even when the winding is wave-wound or the like.

きる。 Also, in the case of a rotating armature type generator in which the output winding 3 is wound on the rotor 5 side, each generator is adjusted so that the center line of the opening of the slot and the center line of the teeth coincide at the symmetrical position of the pair of magnetic poles. By providing a slot, the slot ripple can be reduced in exactly the same way.

As explained above, according to the present invention, each slot is provided and winding is performed so that the center line of the opening of the slot and the center line of the tooth coincide at the symmetrical position of the pair of magnetic poles. The slot ripple of the output voltage can be reduced. This is especially effective for those with flat stators that cannot skew.
またステータを複数個に分割することにより、
いわゆるトロイダル巻が自動巻線機で巻線できる
ようになり、巻線時間が短縮化される。 Also, by dividing the stator into multiple pieces,
So-called toroidal winding can now be wound with an automatic winding machine, reducing the winding time.
