本発明は小型直流モータ等に用いられるカップロータの
製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a cup rotor used in a small DC motor or the like.
コアレスのカップロータは、ロータに鉄心がないためロ
ータの慣性モーメントが非常に小さくコギングがなく、
さらに高効率で小型大出力である等の特徴を有し、種々
の型式のものが提案されている。Coreless cup rotors do not have an iron core, so the moment of inertia of the rotor is extremely small, and there is no cogging.
Furthermore, various types have been proposed, which have characteristics such as high efficiency, small size, and high output.

少なく占積率がよく、ロータカップの肉厚を小にするこ
とができ、慣性モーメントをより小さくできる等の特徴
を有するもので次のように形成される。Among these, the honeycomb winding type has features such as being able to perform aligned winding, having a small number of steps and a good space factor, allowing the thickness of the rotor cup to be reduced, and the moment of inertia to be smaller. It is formed as follows.
即ち第1図に示すように巻枠1にハネカム巻線2を施し
、巻線相互間を固着した後巻枠1を取り外しカップを形
成するものである。That is, as shown in FIG. 1, a honeycomb winding 2 is applied to a winding frame 1, and after the windings are fixed together, the winding frame 1 is removed to form a cup.
ここにハネカム巻とは、巻枠1の前下端P1から後上端
Q1に、該上端Q1から前下端P2へと順次整列巻する
ものである。Here, honeycomb winding refers to sequentially aligned winding from the lower front end P1 of the winding frame 1 to the upper rear end Q1, and from the upper end Q1 to the lower front end P2.
ところがハネカム巻は本来弾性が非常に小さく表面が粗
である滑りにくい繊維糸等に適したものであり、コイル
線をハネカム巻するのは困難である。However, honeycomb winding is originally suitable for fiber yarns that have very low elasticity and rough surfaces and are difficult to slip, and it is difficult to honeycomb wind coil wires.
即ち上下端P1.P2・・・Q□、Q2・・・における
コイル線2′、2“の折り返しが困難であり、特に折り
返し部が近接位置であるため、その製造は一層困難にな
る。That is, the upper and lower ends P1. It is difficult to fold back the coil wires 2', 2'' at P2...Q□, Q2..., and in particular, since the folded portions are located close to each other, manufacturing thereof becomes even more difficult.

The distance between adjacent folded parts is made thicker than between the adjacent coil wires of the central reduced diameter part of the drum to facilitate the formation of the folded part, and the folded parts at both ends of the drum are removed from the jig and the folded parts are attached to the central reduced diameter part. The purpose is to form a cylindrical honeycomb-wound coil body by shaping it to the same diameter.
