Description

本発明は、有底円筒形状のモータケース内に、その外周にコイルが巻かれたステータコアとバスバーとを樹脂で一体成型する回転電機のステータ樹脂成型方法に関するものである。   The present invention relates to a stator resin molding method for a rotating electrical machine in which a stator core and a bus bar, each having a coil wound around an outer periphery thereof, are integrally molded with a resin in a bottomed cylindrical motor case.

従来、コイルが巻かれたステータコアからなるステータと、永久磁石を備えるロータと、から構成され、ステータが樹脂で一体成型されてなるステータ構造を有する回転電機は種々のものが知られている（例えば、特許文献１参照）。そして、外部からステータのスタータコアに巻かれたコイルに電源を供給してコイルに磁界を発生させることで、永久磁石を備えるロータを回転させている。外部からコイルへの電源の供給は、一体に樹脂成型されたステータ構造を介して、接続線を直接外部に取り出すか、バスバーの電源供給用の端子部を外部に露出させる必要があった。
特開２００３−２４４８８０号公報 Conventionally, various types of rotating electrical machines having a stator structure in which a stator including a stator core around which a coil is wound and a rotor including a permanent magnet are integrally formed of resin are known (for example, , See Patent Document 1). And the rotor provided with a permanent magnet is rotated by supplying electric power to the coil wound around the starter core of the stator from the outside and generating a magnetic field in the coil. In order to supply power from the outside to the coil, it is necessary to directly connect the connecting wire to the outside or to expose the power supply terminal portion of the bus bar to the outside through a stator structure integrally molded with resin.

図５は従来の回転電機における樹脂で一体成型されたステータ構造の一例を示す図である。図５に示す例では、一体に樹脂成型されたステータ構造５１を介して接続線５２を外部に取り出している。このような一体に樹脂成型されたステータ構造５１を樹脂成型する場合、全体を成型型にセットした後成型型内に樹脂を注入して成型するが、外部に取り出す接続線５２の部分は開口部となるため、樹脂が漏れる場合があった。図５に示す例では、そのような樹脂の漏れを、接続線５２を固定具５３にて挟み込むことにより防止して、いわゆる樹脂成型時の樹脂切りを行っていた。しかしながら、接続線５２を切断することなく樹脂切りを行うので、挟み込みの調節が困難な問題があった。また、成型型へのセッティングも調節を要する問題もあった。なお、これらの問題は、回転電機がラジアル型かアキシャルギャップ型かによらず発生していた。   FIG. 5 is a view showing an example of a stator structure integrally formed with resin in a conventional rotating electric machine. In the example shown in FIG. 5, the connecting wire 52 is taken out through a stator structure 51 integrally molded with resin. When such an integrally resin-molded stator structure 51 is resin-molded, the whole is set in a mold and then molded by injecting resin into the mold. Therefore, the resin may leak. In the example shown in FIG. 5, such resin leakage is prevented by sandwiching the connecting wire 52 with the fixture 53, and so-called resin cutting is performed during resin molding. However, since the resin is cut without cutting the connection line 52, there is a problem that it is difficult to adjust the pinching. There is also a problem that the setting to the mold needs to be adjusted. These problems occur regardless of whether the rotating electrical machine is a radial type or an axial gap type.

以下に、この発明の実施の形態を、図面に基づき詳細に説明する。
図１及び図２はそれぞれ本発明の回転電機のステータ樹脂成型方法を適用したステータ構造の一例を説明するための図である。図１及び図２にに示す例では、アキシャルギャップ型の回転電機を構成するステータの構造を示しており、このステータに対向して図示しないロータを配置してアキシャルギャップ型の回転電機を構成している。図１及び図２に示す例において、１はステータ、２はコイル、３はステータコア、４はモータケース、１１はバスバー、１２はバスバー１１のコイル２との結線部、１３はバスバー１１のモータへの電源供給用の端子部、１４はモータケース４の底部に設けた開口部である。開口部１４はバスバー１１の端子部１３に対向する位置にのみ設けている。そして、これらの部材をモータケース４と一体に樹脂成型してステータ構造を得ている。 Embodiments of the present invention will be described below in detail with reference to the drawings.
1 and 2 are diagrams for explaining an example of a stator structure to which the stator resin molding method for a rotating electrical machine according to the present invention is applied.

Reference numeral 14 denotes an opening provided in the bottom of the motor case 4. The opening 14 is provided only at a position facing the terminal portion 13 of the bus bar 11. These members are molded integrally with the motor case 4 to obtain a stator structure.

図１及び図２に示す例において、本発明の回転電機のステータ樹脂成型方法の特徴は、有底円筒形状のモータケース４内に、その外周にコイル２が巻かれたステータコア３とバスバー１１とを樹脂で一体成型するにあたり、コイル２との結線部１２とモータへの電源供給用の端子部１３とを除いて予め樹脂成型した円筒形状のバスバー１１を準備し、ステータコア３と予め樹脂成型したバスバー１１とをモータケース４に組み付け、コイル２とバスバー１１の結線部１２とを結線した後、バスバー１１にて樹脂切りを行いつつ樹脂成型する点にある。より具体的には、ステータコア３と予め樹脂成型したバスバー１１とをモータケース４内に組み付けるに際し、モータケース４の底部に設けた開口部１４を介してバスバー１１の端子部１３をモータケース外に突出させるとともに、予め樹脂成型したバスバー１１で開口部１４を塞ぎ、コイル２とバスバー１１の結線部１２とを結線した後、モータケース４の上部を図示しない成型型で密封してモータケース４内に樹脂を注入することにより、バスバー１１にて樹脂切りを行いつつ樹脂成型を行う。   In the example shown in FIGS. 1 and 2, the stator resin molding method for a rotating electrical machine according to the present invention is characterized in that a stator core 3 and a bus bar 11 in which a coil 2 is wound around an outer periphery of a bottomed cylindrical motor case 4.

The bus bar 11 is assembled to the motor case 4, the coil 2 and the connection portion 12 of the bus bar 11 are connected, and then the resin is molded while the resin is cut by the bus bar 11. More specifically, when the stator core 3 and the pre-molded bus bar 11 are assembled in the motor case 4, the terminal portion 13 of the bus bar 11 is brought out of the motor case through the opening 14 provided at the bottom of the motor case 4. After projecting, the opening 14 is closed with a pre-molded bus bar 11, the coil 2 and the connection portion 12 of the bus bar 11 are connected, and then the upper portion of the motor case 4 is sealed with a molding die (not shown). The resin is molded while the resin is cut by the bus bar 11 by injecting the resin.

このように構成することで、従来のように接続線で樹脂切りをする必要が無く、簡単な方法で樹脂成型時のバスバー１１とモータケース４との間からの樹脂漏れを確実に防止することができるとともに、電源供給用の端子部１３を樹脂成型体の外に簡単に出すことができる。   By configuring in this way, there is no need to cut the resin with a connecting line as in the prior art, and it is possible to reliably prevent resin leakage between the bus bar 11 and the motor case 4 during resin molding by a simple method.

In the example shown in FIG. 3, the interface shape between the slot wall and the side surface of the bus bar is tapered, and the bus bar is pressed against the motor case at the time of resin molding, thereby more reliably preventing resin leakage between the bus bar and the motor case. can do.

さらに、図１及び図２に示す例では、バスバー１１とモータケース１４との隙間に、樹脂成型する前に接着剤（図示せず）を充填するよう構成することもできる。このように構成した場合は、充填した接着剤により、バスバー１１やモータケース４の寸法のばらつきを吸収しつつ、バスバー１１とモータケース４との間からの樹脂漏れをより確実に防止することができる。   Furthermore, in the example shown in FIG.1 and FIG.2, it can also comprise so that the clearance gap between the bus-bar 11 and the motor case 14 may be filled with an adhesive agent (not shown) before resin molding. When configured in this way, the filled adhesive can more reliably prevent resin leakage between the bus bar 11 and the motor case 4 while absorbing variations in the dimensions of the bus bar 11 and the motor case 4. it can.

さらにまた、ここでは図示しないが、バスバー１１の端子部１３に樹脂成型により凸部を設け、この凸部とモータケース４の開口部１４とを嵌め合い構造にするよう構成することができる。このように構成することで、バスバー１１の周方向の位置決めをしつつ、沿面距離も確保することができる。   Furthermore, although not shown here, the terminal portion 13 of the bus bar 11 can be provided with a convex portion by resin molding, and the convex portion and the opening portion 14 of the motor case 4 can be fitted together to form a structure. By comprising in this way, the creeping distance can also be ensured, positioning the bus bar 11 in the circumferential direction.
