〔産業上の利用分野〕
本考案は、小型電機用ステータ、特に電機子用
の巻線パターンを予めフレキシブルプリント基板
に形成しておき、該フレキシブルプリント基板を
ステータに密着させ、電機子巻線をステータに巻
装した小型電機用ステータに関するものである。[Detailed description of the invention] [Field of industrial application] The present invention is based on a method in which a winding pattern for a stator for a small electric machine, especially an armature, is formed in advance on a flexible printed circuit board, and the flexible printed circuit board is closely attached to the stator. This invention relates to a stator for a small electric machine in which an armature winding is wound around the stator.
例えば発電機の電機子構造は、界磁回転型の場
合、第４図に示す分布巻線型と第５図、第６図に
示す集中巻線型とが存在する。
For example, in the case of a field rotation type armature structure of a generator, there are two types: a distributed winding type shown in FIG. 4 and a concentrated winding type shown in FIGS. 5 and 6.
第４図に示される分布巻線型にあつては、ロー

ので、ステータ４，７の組立て、すなわち巻線
６，８のステータ４，７への巻装が簡単容易に行
える利点がある。 In the case of the distributed winding type shown in FIG. 4, the magnetic flux density distribution in the air between the rotor (not shown) and the stator 1 can be made into a sine wave, and since it has a winding coefficient, the armature There is an advantage that harmonics can be suppressed by the winding method of the winding 3. On the other hand, the fifth
In the case of the concentrated winding type shown in Fig. 6, the windings 6 and 8 have no coil ends.
The heat generation and copper amount of the windings 6 and 8 are small.
Since the wires can be wound around the bobbin in advance and then assembled, there is an advantage that the assembly of the stators 4 and 7, that is, the winding of the windings 6 and 8 around the stators 4 and 7 can be performed easily and easily.
しかしながら、第４図に示された分布巻線型電
機子構造、第５図、第６図に示された集中巻線型
電機子構造にも次のような欠点がある。
However, the distributed winding armature structure shown in FIG. 4 and the concentrated winding armature structure shown in FIGS. 5 and 6 also have the following drawbacks.
すなわち、第４図に示された分布巻線型にあつ
ては、巻線３がスロツト２内に分布しているため
巻線のスロツト２への挿入、整形の工程を必要と
し、巻線３のコイル・エンド３ａの部分は発電に
寄与せず、損失となる欠点がある。 That is, in the case of the distributed winding type shown in FIG. 4, since the winding 3 is distributed within the slot 2, it is necessary to insert the winding into the slot 2 and shape the winding. The coil end 3a has the disadvantage that it does not contribute to power generation and results in loss.
また、第５図に示された集中巻線型にあつて

〓の磁束密度分布が電機子反作用のため著しく歪
む欠点もある。 In addition, the concentrated winding type shown in FIG. 5 has a structure in which the winding 6 surrounds the iron core 5, which has the disadvantage of increasing inductance. In this case, there is a disadvantage that a large amount of excitation power is required because the magnetic path becomes long. The concentrated winding type shown in FIGS. 5 and 6 also has the disadvantage that the magnetic flux density distribution in the air between the rotor and the stators 4 and 7 (not shown) is significantly distorted due to armature reaction.
