【発明の詳細な説明】
「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 that is constructed by providing a main winding and an auxiliary winding 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
すものでめった。``Prior Art'' In motors in which an auxiliary winding and a main winding are connected in parallel, the windings are attached to a stator core formed with 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が考えられるが
、スロット数を少なくしても、スロット間に股がるよう
に巻線される関係上、巻線の不要部分が長くなり、特性
の改善はできなかった。Therefore, it is possible to reduce the number of slots, but even if the number of slots is reduced, the unnecessary part of the winding will become longer because the wire is wound between the slots, and the characteristics will not improve. could not.
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。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.
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。In such a state, when the power supply voltage is high, the windings become thinner, which causes a rapid increase in the occurrence of defects, making the device impractical.
また、一方、電動機は、回転子と固定子との問に形成さ
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 make this air gap as small as possible.
しかしながら、この空隙を小さくするには、限界があり
、精度の向上には、気かによって切削しなければならな
かった。However, there is a limit to how small this gap can be, and in order to improve accuracy, it has been necessary to cut the gap.
このため、従来は、この空隙を０．１〜０．２５ＩＩｖ
ｎ程度にしていた。For this reason, conventionally, this void was reduced to 0.1 to 0.25 IIv.
I kept it around n.
また、星型の歯部を継鉄部で囲繞する際、歯部が継鉄部
によって内径側へ押されて変形する恐れあり、この継鉄
部に対向することができる構造でなければならなかった
。In addition, when surrounding the star-shaped teeth with a yoke, there is a risk that the teeth may be pushed inward by the yoke and deform, so the structure must be such that it can face the yoke. Ta.
また、継鉄部は、歯部が星型で複数形成されるため、こ
れらの歯部に均等に作用させる必要があり、しかも、歯
部の数が電動機の型式によって異なることがある。Further, since the yoke portion has a plurality of star-shaped tooth portions, it is necessary to act evenly on these tooth portions, and the number of tooth portions may differ depending on the type of electric motor.
この様な場合、歯部の数が異なっても一様に継鉄部が作
用する必要があり、万一歯部によって継鉄部の作用が異
なると一部の歯部が内径側へ押されて回転子と隣接する
内径が偏在して回転子との間に形成されるわずかな空隙
が形成できなくなる。In such cases, the yoke must act uniformly even if the number of teeth differs, and if the yoke acts differently depending on the teeth, some of the teeth may be pushed toward the inner diameter. As a result, the inner diameter adjacent to the rotor is unevenly distributed, making it impossible to form a small gap between the rotor and the rotor.
「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、
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
どが発生しなく、歯部と回転子の間に形成される空隙が
正確に１ｑられ、効率の良い電動機を１ｑ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,
The purpose is to obtain a quiet operating characteristic, easy winding, no insulation failure or disconnection, and an efficient electric motor with an accurate 1q air gap formed between the teeth and the rotor. It is said that

を形成し、このアリを嵌合するアリミゾを継鉄部に形成
し、この嵌合部分の近傍に積層方向の透孔を形成し、こ
のアリおよびアリミゾを積層方向に嵌合することによっ
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 the main winding and auxiliary winding are mounted on a bobbin. A dovetail is formed at the tip of the tooth, a dovetail groove into which the dovetail fits is formed in the yoke, and a through hole in the lamination direction is formed near this fitted part. The problem is solved by fitting these dovetails and dovetails in the stacking direction.

従って、歯部３．３ａと継鉄部４．４ａとは、極めて精
密に内径側の１法が１１られる。Therefore, the tooth portion 3.3a and the yoke portion 4.4a are precisely aligned with each other on the inner diameter side.
すなわち、歯部３．３ａが継鉄部４．４ａに内径側へ押
されることが少なくなり、回転子との隣接面を形成する
歯部３．３ａの内径の偏在をなくすることができる。That is, the tooth portion 3.3a is less likely to be pushed inward by the yoke portion 4.4a, and uneven distribution of the inner diameter of the tooth portion 3.3a forming the adjacent surface with the rotor can be eliminated.
しかも、継鉄部４に凹部を形成することにより、この凹
部を介してプレスの打扱きを行うことで、アリ１０とア
リミゾ１１との精度を向上することができる。Furthermore, by forming a recess in the yoke portion 4, the precision of the dovetail 10 and the dovetail groove 11 can be improved by performing the press operation through this recess.
すなわち、アリ１０とアリミゾ１１とは、同時に打扱い
た形状が好ましいため、この部分を同時に打扱くと、歯
部３の相互間に形成される巻線６が入る空間部分が後の
工程で打扱くことができ、歯部３のと継鉄部４の嵌合部
分のみプレスで打抜くことができるようになる。In other words, it is preferable that the dovetail 10 and the dovetail groove 11 be hammered at the same time, so if these parts are hammered at the same time, the space formed between the teeth 3 into which the winding 6 will fit will be removed in the later process. It can be handled by punching, and only the fitting portion of the tooth portion 3 and the yoke portion 4 can be punched out with a press.
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、歯部３．３ａ
によって正確に形成されるため、機械による切削をなく
することも可能となる。The gap with the rotor formed on the inner diameter side of the toothed portion 3 may be adjusted by cutting with a machine, but the toothed portion 3.3a
Since it is formed accurately by the process, it is also possible to eliminate the need for mechanical cutting.
ざらに、継鉄部４．４ａ側に余計巻装できる巻線方法で
は、巻線６の銅損が少なくなるため、歯部３相互間で巻
線６が大口に巻装できるため効率が向上することになり
、結果として効率が悪化することは少なくなる。Roughly speaking, with the winding method that allows extra winding on the yoke part 4.4a side, the copper loss of the winding 6 is reduced, and the winding 6 can be wound in a large amount between the teeth 3, improving efficiency. As a result, deterioration in efficiency is reduced.
そして、継鉄部４を円筒形すると、歯部３．３ａを放射
状に複数備えても、歯部３のそれぞれが同じ寸法で良く
、継鉄部４についても円内方向に°゛一様の体積に形成
されており、磁束が円周方向に均一に分布できるため、
トルクムラなどによって振動などの障害が発生すること
はなく、静粛な運転ができる。If the yoke portion 4 is cylindrical, even if a plurality of tooth portions 3.3a are provided radially, each of the tooth portions 3 may have the same dimensions, and the yoke portion 4 may also have a uniform angle in the inward direction. Because it is formed in a volume and the magnetic flux can be distributed uniformly in the circumferential direction,
There are no problems such as vibration caused by uneven torque, and quiet operation is possible.
