産業上の利用分野
本発明は、樹脂モールドされるモールドモータに関する
。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a molded motor that is molded with resin.
従来の技術
樹脂モールドされるモールドモータは、固定子鉄心に施
される巻線に電流が流れる際、その巻線の電流により発
生する熱が樹脂モールド層に拡散し、外気に放熱する。BACKGROUND ART In a molded motor that is molded with resin, when current flows through the windings provided on the stator core, the heat generated by the current in the windings is diffused into the resin molded layer and radiated to the outside air.
この放熱性を良くするために、樹脂モールドの量を少な
くしたり、樹脂モールドのベース樹脂の量を少なくする
努力が行なわれている。In order to improve this heat dissipation, efforts are being made to reduce the amount of resin mold or the amount of base resin in the resin mold.
しかしながら、樹脂モールドの量を少なくすると、強度
が少なくなり、かつ成形性が悪くなる傾向があり、放熱
性向上に限界を生じている。However, when the amount of resin mold is reduced, the strength tends to decrease and the moldability tends to deteriorate, which puts a limit on the improvement of heat dissipation.
また、ベース樹脂量を少なくすると、高価なベース樹脂
を節約できるが、樹脂モールド材が放熱性の良い炭酸カ
ルシュームなどの不活性物質を樹脂で何めるように構成
するものであるから、強度が少なくなる傾向があり、前
記樹脂モールドの量を少なくする場合と同じく、放熱性
向上に限界を生じている。In addition, reducing the amount of base resin can save on expensive base resin, but since the resin mold material is composed of resin containing an inert substance such as calcium carbonate, which has good heat dissipation, the strength is reduced. As with the case where the amount of the resin mold is reduced, there is a limit to the improvement of heat dissipation.
そこで、固定子鉄心の外周の一部を樹脂モールドせず、
直接固定子鉄心から放熱されるようにして放熱性を良く
しているモールドモータが製作されるようになっている
。Therefore, we did not mold a part of the outer circumference of the stator core with resin.
Molded motors are now being manufactured that improve heat dissipation by allowing heat to be dissipated directly from the stator core.
発明が解決しようとする課題
しかしながら、前記モールドモータは、樹脂モールド底
形の際、固定子鉄心の樹脂モールドで覆う外周面と樹脂
モールドで覆わない外周面との隣接部で樹脂漏れを生じ
、その固定子鉄心の外周に樹脂が薄く付着したり、球状
の粒が付着したりして、モールド成形時に付着した樹脂
を取る加工を必要としている。Problems to be Solved by the Invention However, when the molded motor has a resin-molded bottom shape, resin leakage occurs at the adjacent portion between the outer circumferential surface of the stator core covered with the resin mold and the outer circumferential surface not covered with the resin mold. A thin layer of resin or spherical particles adhere to the outer periphery of the stator core, requiring processing to remove the resin that adhered during molding.
本発明は、上記課題に鑑みてなされたもので、巻線に流
れる電流により発生する熱を直接固定子鉄心から放熱で
きるモールドモータで、しかも樹脂モールド成形時に樹
脂漏れが生じないモールドモータを得ることを目的とし
ている。The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to obtain a molded motor that can directly radiate heat generated by the current flowing through the windings from the stator core, and that does not cause resin leakage during resin molding. It is an object.
課題を解決するための手段
上記目的を達成するために本発明は、樹脂モールドを施

溝又は穴又は突出部を樹脂モールド成形金型のスライド
コアで押圧するものである。Means for Solving the Problems In order to achieve the above object, the present invention provides grooves, holes, or protrusions on the outer circumferential side of the stator core to which resin molding is applied, so that the stator The grooves, holes, or protrusions of the iron core are pressed by a slide core of a resin molding die.
作用

脂モールド成形時に付着している樹脂を取る加工が不要
となる。Effect With the above configuration, resin leakage during resin molding is prevented by pressing the slide core of the resin molding die against the groove, hole, or protrusion on the outer circumferential side of the stator core. In addition, without covering part of the outer periphery of the stator core with resin mold, the heat generated by the current flowing through the windings on the stator core is directly radiated from the stator core. There is no need to process to remove the resin that is sometimes attached.

If the stator core 1 has a strong structure, one side 6 of the slide core 2 may be configured in this way without any problem. However, if the structure of the stator core 1 is low in strength, as seen in other embodiments shown in FIGS. 4 to 17, it is necessary to It is preferable that the portion corresponding to the stator core corner portion 5 be shaped so that it can be easily deformed.
