【発明の詳細な説明】
本発明は、細形モータに用いる回転子の構造に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a rotor used in a narrow motor.
モータの外径を小さくすると出力を得るに軸方
向に長く形成しなければならず内径側の加工が難
しくなる。 If the outer diameter of the motor is made smaller, it must be made longer in the axial direction to obtain output, making machining the inner diameter side difficult.
特に、内径側に巻線が施されるものについては
組み立て作業上の限界が比較的大きな内径にあつ
て容易に細形にすることができず、アルミ鋳造に
よるカゴ形回転子の場合でも細長ければ鋳造の際
に湯が十分内部まで流れず二次導体の形成上限界
があつた。 In particular, for those with windings on the inner diameter side, the limit in assembly work is the relatively large inner diameter, so it is not easy to make them slender, and even cage-shaped rotors made of cast aluminum cannot be made elongated. For example, during casting, the hot water did not flow to the inside sufficiently, and there was a limit to the formation of the secondary conductor.
この様な事情から、カゴ形回転子の場合の二次
導体に銅製のバーを用いて鉄心スロツトに挿入し
鉄心の両側で銅環を用いて短絡するものが試みら
れているが、多数の銅バーを挿入し短絡する作業
が面倒であり、組み立て後も回転のバランスを得
るに手間であつた。 For this reason, attempts have been made to use copper bars as the secondary conductor for squirrel-cage rotors, insert them into the core slots, and short-circuit them using copper rings on both sides of the core. Inserting the bar and shorting it was troublesome, and even after assembly, it was time-consuming to achieve rotational balance.
本発明は、この様な事情に鑑みて成されたもの
であり、径に関係なく容易に組み立て製作の行え
る回転子を提供することを目的としている。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a rotor that can be easily assembled and manufactured regardless of the diameter.
以下、本発明を図面に示された一実施例にもと

断面図である。 Hereinafter, the present invention will be explained based on an embodiment shown in the drawings.

にいくらか斜めの矩形波状に曲げられている。 As shown in FIG. 2, the steel plate 1 is formed to have a constant width and is bent into a somewhat oblique rectangular wave shape to form a skew.
第３図に於いて、銅板４は鋼板１の凸部２に嵌
合するスリツト５を備えスリツト５の間に導体部
６が形成され、この導体部６を接続するよう短絡
部７が導体部６の両端に一体に形成されている。 In FIG. 3, the copper plate 4 has a slit 5 that fits into the convex part 2 of the steel plate 1, a conductor part 6 is formed between the slits 5, and a short-circuit part 7 connects the conductor part 6. It is integrally formed at both ends of 6.
第４図に於いて、鉄の短冊８は、鋼板１の凸部
２の裏側に嵌合されるよう形成されている。 In FIG. 4, the iron strip 8 is formed so as to be fitted on the back side of the convex portion 2 of the steel plate 1.
第５図に於いて、継鉄を形成する鋼板９に矩形
波状に曲げられた鋼板１が載置されており凸部２
の裏側に短冊８、凹部３に銅板４の導体部６が敷
設されている。 In FIG. 5, a steel plate 1 bent into a rectangular wave shape is placed on a steel plate 9 forming a yoke, and a convex portion 2
A strip 8 is placed on the back side of the plate, and a conductor portion 6 of a copper plate 4 is placed in the recess 3.
そして、短冊８と凸部２の裏側との間には〓間
１０が形成されている。 A gap 10 is formed between the strip 8 and the back side of the convex portion 2.
第６図に於いて、鋼板１の凸部２が鋼板９側へ
押圧し偏平に形成されており、銅板４の導体部６
が把持されている。 In FIG. 6, the convex portion 2 of the steel plate 1 is pressed against the steel plate 9 side and is formed flat, and the conductor portion 6 of the copper plate 4
is being held.
第７図に於いて、回転子は、第６図に示された
組み立て状態から鋼板９を外側にして円筒状に曲
げられて形成されており、凸部２が内径側にな
り、図示されない支持構造によつて回転するよう
構成されている。 In FIG. 7, the rotor is bent into a cylindrical shape with the steel plate 9 outside from the assembled state shown in FIG. The structure is configured to rotate.
そして、軸１１に固定され巻線１２が施された
固定子１３が回転子の内径側に設けられている。 A stator 13 fixed to the shaft 11 and provided with a winding 12 is provided on the inner diameter side of the rotor.
この様な構成に於いて、回転子は、鋼板１を第
１図及び第２図に示される通り、矩形波状に成形
し、第５図に示される通り、銅板４及び鉄の短冊
８を夫々凹部３及び凸部２の裏側に敷設し第６図
に示される通り押圧偏平にする。 In such a configuration, the rotor is formed by forming a steel plate 1 into a rectangular wave shape as shown in FIGS. 1 and 2, and forming a copper plate 4 and an iron strip 8, respectively, as shown in FIG. It is laid on the back side of the concave portion 3 and the convex portion 2 and pressed flat as shown in FIG.
そして、円筒状に曲げ両端を溶接等で接合し円
筒状の回転子を形成する。 Then, it is bent into a cylindrical shape and both ends are joined by welding or the like to form a cylindrical rotor.
この様に形成される回転子は、鋼板１を矩形に
成形する際の矩形波形状の幅と円筒状に曲げた際
の径との関係によつてスロツト数を任意に設ける
ことができる他、軸方向の長さに無関係に製作で
きるため細長く形成するにまつたく困難がない。 The rotor formed in this manner can have an arbitrary number of slots depending on the relationship between the width of the rectangular wave shape when the steel plate 1 is formed into a rectangular shape and the diameter when bent into a cylindrical shape. Since it can be manufactured regardless of the length in the axial direction, there is no difficulty in forming it into a long and thin shape.
また、製作上、継鉄を形成する鋼板９について
管材を用いて製作することもでき、この場合、鋼
板１と銅板４及び短冊８とを一体にして円筒状に
成形しておき、管材で形成された鋼板９に挿入し
て構成すればよい。 In addition, the steel plate 9 that forms the yoke can also be manufactured using a pipe material. In this case, the steel plate 1, the copper plate 4, and the strip 8 are integrally formed into a cylindrical shape, and then the steel plate 9 forming the yoke is formed using a pipe material. What is necessary is just to insert it into the steel plate 9 which has been prepared.
このような短冊８は、固定子の構造に合わせ
て、導体部６の幅及び導体部間の磁性体部の幅を
任意に設定できるため効率の良い電動機を構成す
ることができる。 In such a strip 8, the width of the conductor portion 6 and the width of the magnetic material portion between the conductor portions can be arbitrarily set according to the structure of the stator, so that an efficient electric motor can be constructed.
そして、回転子の内径側の精度は、最終工程で
エキスパンド処理等内径側より半径方向に広げる
ための処理を施せば外側に形成される円筒状の鋼
板９との間で凸部２等が圧潰され回転子として高
い精度を得ることができる。 The accuracy of the inner diameter side of the rotor can be improved by applying processing such as expansion treatment to expand the rotor in the radial direction from the inner diameter side in the final process. High accuracy can be obtained as a rotor.
さらに、回転子は、本実施例の如く外回転型の
モータの他、円筒に曲げる際凸部２を外側にして
内回転型のモータを形成するものにも同様に採用
できる。 Furthermore, the rotor can be similarly adopted in addition to an external rotation type motor as in this embodiment, as well as one in which the convex portion 2 is turned outside when bent into a cylinder to form an internal rotation type motor.
この様な回転子は、凸部２が押圧偏平する際銅
板４を把持するよう周方向へ偏平になり固定子に
対する鋼板１の対向面積が拡大されるため効率を
向上することができ、しかも導体部６の短絡部７
が、予め形成されており後加工が不要であり、ス
キユーの形成に全く困難がなく均一に製作するこ
とができるため電気的特性上極めて好ましいモー
タを得ることができる。 In such a rotor, when the convex portion 2 is flattened by pressing, it becomes flattened in the circumferential direction so as to grip the copper plate 4, and the opposing area of the steel plate 1 to the stator is expanded, so that efficiency can be improved. Short circuit part 7 of part 6
However, since they are formed in advance and no post-processing is required, there is no difficulty in forming skews and they can be manufactured uniformly, making it possible to obtain a motor with extremely favorable electrical characteristics.
また、スキユーの形成は、回転子側で形成する
ことも可能であるが、固定子１３側で形成し、回
転子には形成しないことも可能である。 Furthermore, although it is possible to form the skew on the rotor side, it is also possible to form it on the stator 13 side and not on the rotor.
本実施例により回転子を形成する場合、好都合
な寸法の一例を示すと、鋼板１に0.5mm厚のspc−
ｃ、銅板４に４mm厚、鉄の短冊８に２mm厚、継鉄

スロツト程度の回転子を構成することができる。 When forming a rotor according to this embodiment, an example of convenient dimensions is that the steel plate 1 has a 0.5 mm thick spc-
c. The copper plate 4 is 4 mm thick, the iron strip 8 is 2 mm thick, the steel plate 9 forming the yoke is 1.6 mm thick, and 10

ものであり、その効果は産業上極めて大である。 As explained above, according to the present invention, a rotor with an extremely small diameter can be easily constructed, has high efficiency without deteriorating the electrical characteristics, and can be made arbitrarily long in the axial direction. Therefore, it is possible to obtain a motor with an elongated shape that has not been seen before, and its effects are extremely large in industry.
