「産業上の利用分野」
本発明は、主巻線および補助巻線をボビンに施して構成
される電動機に関する。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an electric motor configured by having a main winding and an auxiliary winding arranged on a bobbin.
「従来の技術」
補助巻線と主巻線とを並列接続する電動機は、内径側へ
多数の歯部が突出して形成された固定子鉄心に巻線を施
すものであった。"Prior Art" A motor in which an auxiliary winding and a main winding are connected in parallel has been wound around a stator core having a large number of teeth protruding toward the inner diameter.
この様な電動機は、固定子の歯部相互間に形成されるス
ロット数が多く、このスロットに主巻線および補助巻線
を施すことは容易ではなかった。Such electric motors have a large number of slots formed between the teeth of the stator, and it is not easy to provide main windings and auxiliary windings in these slots.
このため、スロット数を少なくすることか試みられだが
、トルクムラや振動が多く、特に運転効率を良くするた
めに固定子と回転子との空隙を少なくするとこの傾向が
強くなり、静粛な機器に使用される電動様としては好ま
しくないといった結果になった。For this reason, attempts have been made to reduce the number of slots, but there are many torque irregularities and vibrations, and this tendency becomes stronger when the air gap between the stator and rotor is reduced to improve operating efficiency. The result was not desirable for electric vehicles.
そこで、従来外径側が一体で内径側へ突出していた歯部
を、内径側で一体にして外径側を開放する星型に形成し
て、外径側から巻線を施すように構成したものが試みら
れ、巻線を容易にする点で効果を得ていた。Therefore, the teeth, which were conventionally integrated on the outer diameter side and protruded toward the inner diameter side, are now integrated on the inner diameter side and formed into a star shape with the outer diameter side open, so that the winding can be applied from the outer diameter side. has been tried, and has been effective in making winding easier.
しかしながら、星型に形成された歯部に巻線を施してか
ら、外径側に歯部相互の磁路を形成する継鉄部を装着す
ると、巻線に傷等が発生し易く絶縁不良や断線等の障害
を発生した。 ”この様な状態では、電源電圧が高
い場合は、巻線が細くなるため、不良の発生が急増し、
実用性がなくなるといった問題を有していた。However, if a yoke that forms a magnetic path between the teeth is installed on the outer diameter side after winding the star-shaped teeth, the windings are likely to be damaged, resulting in poor insulation. A failure such as a disconnection has occurred. ``Under these conditions, when the power supply voltage is high, the winding becomes thinner, so the number of defects increases rapidly.
This had the problem of being impractical.
また、一方、電動機は、回転子と固定子との間に形成さ
れる空隙が運転効率を左右させるため、できるだけこの
空隙を小さくする努力がなされていた。On the other hand, since the air gap formed between the rotor and stator of an electric motor affects the operating efficiency, efforts have been made to reduce this air gap as much as possible.
しかしながら、この空隙を小さくすることによって効率
が向上するものの加工が困難になること、および磁束が
南部に偏在するため、]辰動が発生し易く騒音が増加す
る傾向にあった。However, although reducing the gap improves efficiency, it also makes machining difficult, and because the magnetic flux is unevenly distributed in the southern part, sliding motion tends to occur and noise tends to increase.
このため、従来は、この空隙を0.1〜0.25m程度
にしていた。For this reason, conventionally, this gap has been set to about 0.1 to 0.25 m.
「発明が解決しようとする問題点」
本発明は、この様な事情に鑑みてなされたものであり、
巻線をボビンに巻装することに着目し、静粛な運転特性
が得られ巻線が容易で絶縁不良や断線などが発生しない
電動■を1ひることを目的としている。"Problems to be Solved by the Invention" The present invention has been made in view of these circumstances,
Focusing on winding the winding on a bobbin, the aim is to create an electric motor that has quiet operating characteristics, is easy to wind, and does not suffer from poor insulation or disconnection.
「問題点を解決するための手段」
本発明は、固定子鉄心を星型の歯部とこの歯部を囲繞す
る円筒の継鉄部とで構成し、主巻線および補助巻線をボ
ビンに巻装して前記歯部に嵌合したことによって問題点
を解決している。"Means for Solving the Problems" The present invention consists of a stator core consisting of a star-shaped toothed part and a cylindrical yoke part surrounding this toothed part, and a main winding and an auxiliary winding arranged on a bobbin. The problem is solved by wrapping it around and fitting it into the teeth.
「作用」
ボビンに巻線を巻装してから歯部に装置するため、巻線
の線径に無関係に巻線が巻装でき、信頼性が極めて高く
なる。"Operation" Since the winding is wound on the bobbin and then attached to the teeth, the winding can be wound regardless of the wire diameter of the winding, resulting in extremely high reliability.
しかも、ボビンに巻線を巻装する場合、ボビンを回転し
て巻装することができるため、高速度で巻装でき、さら
に、巻線が整然と巻装でき線積率が高くなる。Moreover, when winding the winding around the bobbin, the bobbin can be rotated to wind the winding, so the winding can be done at high speed, and furthermore, the winding can be wound in an orderly manner, resulting in a high wire area factor.

ビン5に施されてd3す、しかも鍔すが形成されている
ため、巻線6に対する悪影響を遮断することができ、巻
線6の不良発生の原因を生じることはない。In this case, the dovetail 10 is placed adjacent to the winding 6, but since the winding 6 is attached to the bobbin 5 and a flange is formed, an adverse effect on the winding 6 can be blocked. This will not cause any defects in the winding 6.
さらに、ボビン5は、歯部3の磁路2に嵌合される際、

It does not have to be press-fitted, but may be a loose fit, and since it is fixed by molding with resin, there is no mechanical movement, and there is no cause of vibration or torque unevenness.
また、ボビン5に外径方向に余計に巻線6を施すように
形成し、放射状の磁路2に嵌合すること、およびこれら

、歯部3の内径が正確に位置決めされ、回転子とのくう
げを極めて小さくできる。Roughly speaking, in terms of manufacturing, by aligning the part of the shield where the dovetail 10 of the tooth part 3 is formed with the inner diameter side of the yoke part 4, the inner diameter of the tooth part 3 is accurately positioned, and the connection with the rotor is ensured. It can make the dents extremely small.
この様に歯部3の内径側に形成される回転子との空隙は
、機械による切削で調整されても良いが、大きくて損失

互間で巻線−6が大組に巻装できるため効率が向上する
面があり、結果として効率が悪化することは少なくなる
。In this way, the gap between the rotor and the inner diameter side of the tooth section 3 may be adjusted by mechanical cutting, but even if it is large and the loss increases, the gap between the rotor and the rotor formed on the inner diameter side of the tooth section 3 may be adjusted by machine cutting. In the winding method in which the wire is wound around the toothed portion 3 by the wire 5, the copper loss of the winding 6 is reduced, and the wire area factor is high, and the winding 6 is wound in large sets between the toothed portions 3. As a result, efficiency is improved, and as a result, efficiency is less likely to deteriorate.
