〔産業上の利用分野〕
本発明はモータにおけるステータを液体により直接に冷

ビルトインモータの冷却に利用可能である。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cooling structure for directly cooling a stator of a motor with a liquid. Therefore, it can be used to cool the built-in motor of the main shaft of a machine tool.
従来、ステータを液冷する場合には、ステータにスリー
ブを被せ、該スリーブを介して冷却する（１）
構造が一般的に採用されている。Conventionally, when a stator is liquid-cooled, a structure has generally been adopted in which the stator is covered with a sleeve and the stator is cooled through the sleeve (1).
然しながら、スリーブを介することは冷却効率を低下さ

特に、コンパクト化の要請されるビルトインモータにお
いては欠点となる。However, using a sleeve reduces cooling efficiency and increases the outer diameter of the motor.
This is particularly a drawback in built-in motors that are required to be compact.
依って本発明は冷却効率を向上させると共に、コンパク

提供する。In view of the above object, the present invention provides a cooling structure for a stator, in which the stator is formed by laminating and press-bonding a plurality of laminating element plates coated with an organic adhesive on both sides, and the outer surface of the stator is To provide a liquid cooling structure for a stator, which is characterized in that a plating layer is applied and the surface of the plating layer is directly liquid cooled.

への影響はないといえる。(2) [Function] Organic adhesive alone is not reliable enough to seal between the laminated element plates, so a plating layer is applied to the outer surface of the laminated stator to improve sealing performance. secure. Since the thickness of the plating layer is small, it can be said that it has no effect on the outer diameter of the motor.
以下本発明を添付図面に示す実施例に基づき更に詳細に
説明する。The present invention will be described in more detail below based on embodiments shown in the accompanying drawings.
モータ用のステータ１０は一般に薄板１２を互いに積層
することによってそのコア部を形成している。A stator 10 for a motor generally has its core formed by laminating thin plates 12 together.
この積層用の各薄板１２の両面には、有機接着剤がコー

するとコーティング接着剤が溶融し、各薄板１２は互い

程度であり、メッキ後にその表面を研摩して仕上げを行

性を有している。Both sides of each thin plate 12 for lamination are coated with an organic adhesive, and when the laminated thin plates 12 are heated, the coating adhesive melts and the thin plates 12 are bonded and bonded to each other. . In this case, since the laminated core is pressed in its longitudinal direction, the spaces between the thin plates 12 are generally sealed. However, since it is not possible to guarantee a completely sealed state (3) without leaking the coolant on the outer surface, the outer surface 14 of the stator core after crimping is ground and then hard chrome plating is applied. The thickness of this plating layer 16 is 0.1~0゜5mII+
After plating, the surface is polished and finished. The above-mentioned hard chrome plating has properties suitable for mechanical polishing.

可能となる。The stator 10 is completed by winding the core constructed in this way, and the stator 10 is inserted into a jacket 18 provided with a coolant flow path 20 on the inner periphery.
Seal by 2. In this way, the liquid cooling structure of the stator 10 is completed, and by flowing the cooling liquid into the flow path 20, the stator 10 is cooled from the outer surface via the plating layer 16 with a thickness on the order of 0.1 mm. , it becomes possible to provide a compact liquid-cooled stator with improved cooling efficiency.

As a result, it becomes possible to provide a motor that is compact and has high cooling efficiency.
