Description

【考案の詳細な説明】 本考案は、固定子、この固定子の両側部に突出すル固定
子巻線のコイルエンド及びこのコイルエンドをつは′状
に包囲する軸受ブラケットよりなる空所にモールド材を
充填したモールド形電動機に関する。[Detailed description of the invention] The invention is based on a hollow space consisting of a stator, coil ends of the stator windings protruding from both sides of the stator, and a bearing bracket surrounding the coil ends in the shape of a square. This invention relates to a molded electric motor filled with molding material.

本考案の目的は、簡単で、特に大量生産に適し、しかも
電動機巻線の良好な熱放出並びに高度の絶縁強度を特に
湿気ないしは水蒸気を多く含んだ大気中で用いた場合で
も保証しうる、モールド巻線を有するコンパクトなモー
ルド形電動機を提供することにある。The object of the invention is to create a molded mold which is simple, particularly suitable for mass production and which, at the same time, ensures good heat dissipation as well as a high dielectric strength of the motor windings, especially when used in humid or water vapor-rich atmospheres. An object of the present invention is to provide a compact molded electric motor having windings.

ンドに密着させることによって達成される。According to the present invention, this object is achieved by inserting a net-shaped insulating spacer between a bearing bracket and a coil end, and providing a bearing bracket for compressing the coil end through the insulating spacer, and attaching the bearing bracket to the coil end. This is achieved by tightly fitting the coil end.

本考案のこのような構成によれば、巻線の巻装後の不定

わせて耐水・耐湿性の電動機を提供できる。According to this configuration of the present invention, the axial length of the motor can be minimized because the irregular coil end is formed after the winding is wound and the bracket is attached.
The distance between the coil end and the bracket ensures a minimum insulation distance and reduces thermal resistance to improve heat dissipation, and at the same time, it is possible to provide a water-resistant and moisture-resistant electric motor.

本考案は、次のような組立工程、モールド工程及びそれ
に続く電動機全体としての完成組立工程に利用できる。The present invention can be used in the following assembly process, molding process, and subsequent complete assembly process of the electric motor as a whole.

挿入のために一時的に再び取外される。That is, each integral bearing bracket placed on the sealing and assembly cylinder is combined with the stator core to form a mold mold closed on both sides of the stator, and after injection and curing of the mold resin, One of the bearing brackets of the assembled electric motor is temporarily removed again for the purpose of pulling out the sealing and assembly cylinder and subsequently inserting the rotor.

ることができる。The cost of removing the sealing/assembly tube and subsequent rotor insertion is to place the sealing/assembly tube on one side of the wound stator core to form a closed mold. An integral bearing bracket 1~ placed on the stator core is provided with an outer part of a two-part bearing bracket extending radially inward to the sealing/assembling cylinder on the other side of the stator core. After centering at the assembly cylinder, it is connected to the stator core, and the inner part of the two-piece bearing bracket is closed to the outside only after the sealing and assembly cylinder is removed and the completed rotor is inserted. This can be further reduced by being firmly connected to the parts.

本考案によって作られる電動機の製作時間は次のように

ットによりスペーサを介して圧縮成形され、特別な補強
手段、特に補強バンドなしにコイルエンドが作られる。That is, by first inserting a mesh insulating spacer into the stator core wrapped with windings and attaching the bearing bracket or its outer part, each coil end is fixed in its final shape and location, especially the outer circumferential bearing. A relative fixation to the bracket takes place, ie the coil end is compression molded by the bracket via the spacer, and the coil end is produced without special reinforcing means, in particular reinforcing bands.

れた網状の箔を挿入する。At least the unfixed coil ends are enclosed in order to ensure the necessary insulation distance to the bearing bracket, on the one hand, and, on the other hand, to ensure a good dissipation of the heat generated in the winding to the outside through the molding material. A perforated mesh foil is inserted as an insulating spacer between the pot-shaped bearing bracket part and the coil end before molding.

その場合、網状の穿孔によって、軸受ブラケットの内壁

い気泡が含まれるのを避けることができる。In this case, the mesh-like perforations make it possible to avoid undesirable air bubbles between the inner wall of the bearing bracket or the coil end and the mounted foil.

覆体で被うのがよい。In order to achieve greater safety against the inclusion of undesired air bubbles and a tighter filling of the air gap between the coil end and the inner wall surface of the associated bearing bracket, a pot-shaped bearing bracket part can be used as an insulating spacer. It is advisable to insert a textile insert or to cover the coil ends with a textile covering.

その場合、織物状の挿入物はモールド材に対する所定の
吸着性によって特徴づけられる。In that case, the textile insert is characterized by a certain adhesion to the molding material.

コイルエンドのモールドの際には温度モニタや安全ヒユ
ーズのような、巻線と結合すべき他の電気部品も同時に
一緒にモールドするのがよい。When molding the coil ends, it is also a good idea to mold other electrical components to be coupled to the windings, such as temperature monitors and safety fuses, at the same time.

が最少絶縁距離に対する必要な壁厚を越えるような所に
配置される。Such electrical components are arranged in the molding, in particular in such a way that this molding exceeds the required wall thickness for the minimum insulation distance.

ための固定手段を備えるようにしてもよい。According to another embodiment of the invention, before the molding, a fixing member is inserted through the opening of the casing part containing the bearing bracket, one end of which is molded into the molding material, and the other end of which is inserted into the outside of the motor. It is also possible to provide fastening means for the components, for example fastening parts such as terminal boards, fuse boxes or the motor itself.

荷に耐えるようにすることができる。In this way, the fastening elements can be easily installed and, by being co-molded in the molding material, can withstand relatively high loads from other motor components, even in the case of relatively fragile bearing bracket parts or casing parts. can do.

ことができる。Although the heat of the windings can be effectively dissipated to the outside by making the shape of the bearing bracket into a pot shape that matches the shape of the coil end and maintaining the appropriate spacing with an insulating spacer, other cooling methods, especially the stator Cooling of the inner coil end space between the end face of the iron core and the coil end is achieved by inserting a cylindrical air guide section between the coil ends, especially between the coil ends, and cooling the opening of the inner coil end space between the end face of the iron core and the coil end. This can be achieved by affixing the end in correspondence with the inlet or outlet in the casing part containing the bearing bracket.

．． 42 is compressed, placed in its final position and held at a distance from the surrounding electrically conductive bearing brackets 5, 6 by means of a perforated mesh foil 7 at a distance required for insulation purposes. .
