されていた。2. Description of the Related Art Conventionally, this type of squirrel cage rotor is generally constructed by providing a plurality of slots 52 on the outer periphery of a circular thin iron plate 51 shown in FIG. As shown in FIG. 5, the conductor 53 was inserted into the slot 52, and the ring-shaped end ring 54 and the conductor 53 were connected at both end faces by caulking or ultrasonic bonding. .
発明が解決しようとする課題
このような従来の構成では、スロット５２の開口部５６

ロット５２内が三次元的にひねった形状をなしており、
たいへん作業性の悪いものであった。Problems to be Solved by the Invention In such a conventional configuration, the opening 56 of the slot 52
Since the conductor 53 is narrow, the conductor 53 is inserted from the same direction as the lamination of the thin iron plates. It has a twisted shape,
It was very difficult to work with.
本発明はこのような課題を解決するもので、容易にスロ
ット内に導体を挿入することができて、コストの低減が
できるかご形回転子を提供することを目的とするもので
ある。The present invention has been made to solve these problems, and an object of the present invention is to provide a squirrel cage rotor in which conductors can be easily inserted into slots and costs can be reduced.
課題を解決するための手段
本発明は上記目的を達成するために、円形の外周に、外
周端が開口したＵ形状のスロットを複数個有する薄鉄板
を積層した鉄心の前記スロット内に、平板状の導体を前
記開口から挿入配設してなる構成としたものである。Means for Solving the Problems In order to achieve the above object, the present invention has a flat plate-like slot in an iron core in which thin iron plates are laminated, each having a plurality of U-shaped slots with open outer edges on a circular outer periphery. A conductor is inserted and disposed through the opening.
作 用
本発明は上記した構成により、スロットがＵ形状をして
いるので、板状の導体をその開口部から容易に挿入でき
ることとなる。Effects According to the present invention, since the slot is U-shaped with the above-described configuration, a plate-shaped conductor can be easily inserted through the opening.
実施例
以下、本発明の一実施例について第１図〜第３図を参照
しながら説明する。EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.
第１図および第２図に示すように、円形の薄鉄板１の外
周に、その外周端に開口部２を有するＵ形状のスロット
３を複数個設け、この薄鉄板１を複数枚積層して積層鉄
心４を形成している。この積層時、スロット３は、所定
の傾きでスキューされている。そして、第３図に示すよ
うにスロット３内に導体５を挿入し、その両端部を積層
鉄心４の両端面で、リング状の導体であるエンドリング
６にカシメ、あるいは超音波接合によって連結し、この
ようにしてかご形回転子７は構成されている。As shown in FIGS. 1 and 2, a plurality of U-shaped slots 3 having an opening 2 at the outer peripheral end are provided on the outer periphery of a circular thin iron plate 1, and a plurality of thin iron plates 1 are laminated. A laminated iron core 4 is formed. During this stacking, the slots 3 are skewed at a predetermined inclination. Then, as shown in FIG. 3, a conductor 5 is inserted into the slot 3, and both ends of the conductor 5 are connected to an end ring 6, which is a ring-shaped conductor, on both end surfaces of the laminated core 4 by caulking or ultrasonic bonding. , thus the squirrel cage rotor 7 is constructed.
上記構成において、導体５のスロット３内−１の挿入は
、スロット３がＵ形状であるため、開Ｏ部２から導体５
を容易に挿入することができ、さらに導体５を平板状と
しているので、その挿入固定は確実なものとなる。In the above configuration, since the slot 3 is U-shaped, the conductor 5 is inserted into the slot 3-1 from the open O part 2.
The conductor 5 can be easily inserted, and since the conductor 5 has a flat plate shape, its insertion and fixation can be ensured.
なお、本実施例のかご形回転子７は、三相、単相いずれ
の誘導電動機にも適用できるものである。Note that the squirrel cage rotor 7 of this embodiment can be applied to either a three-phase or a single-phase induction motor.
