本発明はコアレスモーターのステーターブロックの製法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a stator block for a coreless motor.
従来のステーターブロックは第１図に示すように、一面
開口筒状をなし、その底面に形成した樹脂流入孔イから
成形樹脂口を流入させ、・その底面に磁石ハを一体的に
固着していた。As shown in Figure 1, a conventional stator block has a cylindrical shape with an opening on one side, a molded resin port is introduced through a resin inlet hole A formed on the bottom surface, and a magnet C is integrally fixed to the bottom surface. Ta.
しかしながら、このようなステーターブロックの樹脂流
入孔イでは、矢印Ａ方向から流入した樹脂の流れがさえ
ぎられて、矢印Ｃ，Ｄ方向へ分散してしまい、Ｄ方向へ
流れた樹脂圧によって磁石ハが内側へ押圧されてしまい
、従って、磁石ハの円弧状の外周面に成型パリが突出す
ることになり、磁石の組合せ寸法がｌ」・さくなって特
性の低下を招く原因となった。However, in such a resin inlet hole A of the stator block, the flow of resin flowing from the direction of arrow A is blocked and dispersed in the directions of arrows C and D, and the resin pressure flowing in the direction D causes the magnet H to The magnet was pressed inward, and as a result, the molded part protruded from the arcuate outer circumferential surface of the magnet C, causing the combined dimensions of the magnet to become smaller by 1" and resulting in a deterioration in characteristics.
本発明はこのような従来の欠点に鑑みて成したもので、
ヨークの底面中央の樹脂流入孔の周縁より傾斜片を突設

石の外周面より成型パリが突出するのを防止せんとする
ものである。The present invention was made in view of these conventional drawbacks.
A slanted piece is provided protruding from the periphery of the resin inflow hole in the center of the bottom of the yoke to prevent the molded part from protruding from the outer peripheral surface of the semi-cylindrical magnet that is integrally molded into the inner cavity of the yoke. be.
以下、本発明を実施例図面に基づいて説明する。Hereinafter, the present invention will be explained based on the drawings.

。FIG. 3 is a sectional view of one embodiment of the stator block of the coreless motor of the present invention, and FIG. 4 is a front view of the magnet.
図において、１は平面部に縦溝２を形成した略半円柱状
をなす磁石で、その縦溝２の一方の端部には傾斜面２ａ
を形成している。In the figure, reference numeral 1 denotes a semi-cylindrical magnet with a vertical groove 2 formed on its flat surface, and one end of the vertical groove 2 has an inclined surface 2a.
is formed.
３は鉄板を絞り加工して一面開口筒状に形成したヨーク
で、その底面中央には樹脂流入孔３ａを形成している。Reference numeral 3 denotes a yoke formed by drawing an iron plate into a cylindrical shape with an opening on one side, and a resin inflow hole 3a is formed in the center of the bottom surface of the yoke.
本発明コアレスモーターのステーターブロックは上記し
たように、平面部の縦溝の一方の端部に傾斜面を形成さ
せ一対の磁石を、その平面部を当接させて、該傾斜面を
樹脂流入孔の内側に対向させて配設して、樹脂流入孔よ
り柱入した合成樹脂はその傾斜面故に縦溝の内側へ流入
しやすくなっているので、縦溝の内面を押圧する成形樹
脂の押圧力で磁石の外周面を成形金型の内面に密接させ
ることができ、磁石の外周面からの成型パリが突出する
のを防止できる。As described above, in the stator block of the coreless motor of the present invention, an inclined surface is formed at one end of the longitudinal groove of the flat part, a pair of magnets are brought into contact with the flat part, and the inclined surface is connected to the resin inflow hole. The synthetic resin inserted into the column from the resin inflow hole is easily flowed into the inside of the vertical groove due to its sloping surface, so the pressing force of the molded resin pressing against the inner surface of the vertical groove is reduced. This allows the outer circumferential surface of the magnet to be brought into close contact with the inner surface of the molding die, thereby preventing molding particles from protruding from the outer circumferential surface of the magnet.
従って、成型パリを除去する工数を必要とせず磁石の外
周面とヨークの内面とで形成されるコイル収容の空隙の
大きさを全周にわたって精度よく構成できモータの性能
を安定させる効果がある。Therefore, the size of the air gap for accommodating the coil formed between the outer circumferential surface of the magnet and the inner surface of the yoke can be configured with high accuracy over the entire circumference without requiring the man-hours of removing molding particles, which has the effect of stabilizing the performance of the motor.
