Description
本発明は、リニアモータコイルアセンブリ構造に関し、特に、コイルとベースの挿着溝の内壁とが接触する面積を増大させ、放熱速度を向上させるリニアモータコイルアセンブリ構造に関する。 The present invention relates to a linear motor coil assembly structure, and more particularly to a linear motor coil assembly structure that increases an area in which a coil and an inner wall of an insertion groove of a base are in contact with each other and improves a heat dissipation rate.
一般のコアレスリニアモータのコイルアセンブリは、コイル体の外側が樹脂封止層で覆われ、ベースの凹溝の中に配置されている。しかし、樹脂封止層が高分子プラスチック材料からなるため、放熱効果が好ましくなく、コイルの巻取り線に通電されると過熱する虞があった。 In the coil assembly of a general coreless linear motor, the outer side of the coil body is covered with a resin sealing layer, and is arranged in the concave groove of the base. However, since the resin sealing layer is made of a polymer plastic material, the heat dissipation effect is not preferable, and there is a possibility of overheating when the coil winding wire is energized.
従来、コイル体のコイルが過熱することを防ぐために、例えば、特許文献１に示すように、電機子巻線の温度上昇を低減させる技術が開示されている。この特許文献１では、コアレスリニアモータの可動子が複数のコイルからなる電機子巻線と、電機子巻線を支持する可動子取付台とから構成されるとともに、固定子が複数の磁極を形成する永久磁石と、バックヨークとから構成され、さらには、電機子巻線の左右両側を空隙を介して永久磁石で挟み込むように構成されたコアレスリニアモータにおいて、可動子取付台の下面に凹部を設けるとともに、コイルの上側にあたるコイル上辺を、可動子取付台の凹部内に挿入し、コイルの下側にあたるコイル下辺の近傍にコイル間もしくはリード線との結線処理を行うスペースを設ける。しかし、この従来技術には、以下のような欠点があった。 Conventionally, in order to prevent the coil of the coil body from overheating, for example, as shown in Patent Document 1, a technique for reducing the temperature rise of the armature winding has been disclosed. In Patent Document 1, a mover of a coreless linear motor is composed of an armature winding composed of a plurality of coils and a mover mounting base that supports the armature winding, and the stator forms a plurality of magnetic poles. In the coreless linear motor, which is composed of a permanent magnet and a back yoke, and further sandwiched between the left and right sides of the armature winding with a permanent magnet through a gap, a recess is formed on the lower surface of the mover mounting base. In addition, the upper side of the coil corresponding to the upper side of the coil is inserted into the concave portion of the mover mounting base, and a space is provided in the vicinity of the lower side of the coil corresponding to the lower side of the coil to perform a connection process between the coils or the lead wire. However, this conventional technique has the following drawbacks.
可動子取付台の凹部内にコイルを直接挿入して放熱速度を向上させていたが、コアレスリニアモータの応用上、効率を高めるに従い、コイルに通電させる電流が大きくなる。所定の推力を発生させるために、必要な電流が印加されると、コイルにはその電流の２乗に比例したジュール熱が発生する。そのため、放熱速度を高める必要があった。 Although the heat dissipation speed has been improved by directly inserting the coil into the recess of the mover mounting base, the current to be supplied to the coil increases as the efficiency is increased for the application of the coreless linear motor. When a necessary current is applied to generate a predetermined thrust, Joule heat proportional to the square of the current is generated in the coil. Therefore, it was necessary to increase the heat dissipation rate.
本発明の目的は、コイルとベースの挿着溝の内壁とが接触する面積を増大させてコイルとべースとの間の熱伝導率を向上させる上、冷却チャネルによりベースと空気との熱対流を加速させ、放熱速度を大幅に向上させるリニアモータコイルアセンブリ構造を提供することにある。 The object of the present invention is to increase the area of contact between the coil and the inner wall of the insertion groove of the base so as to improve the thermal conductivity between the coil and the base, and to achieve thermal convection between the base and the air by the cooling channel. It is an object of the present invention to provide a linear motor coil assembly structure capable of accelerating heat dissipation and greatly improving the heat dissipation rate.
本発明のもう一つの目的は、ベースの挿着溝の表面に形成した絶縁薄膜により、コイルとベースとの間の絶縁性を高めるリニアモータコイルアセンブリ構造を提供することにある。 Another object of the present invention is to provide a linear motor coil assembly structure that enhances the insulation between the coil and the base by an insulating thin film formed on the surface of the insertion groove of the base.

コイル体Ｃのコイル１は、非作用辺の第２の側部１２に配置された複数のワイヤ１６を有する。これらワイヤ１６は、コイル体端部１８の非作用辺の第２の側部１２へ延設した後、コイル体端部１８のコイル１の直線作用辺１０まで折り曲げ、外部ケーブルＢと接続して導通し、外部電流がコイル体Ｃを通って作用し、コイル１の第３の折り曲げ部１５によりワイヤ１６を案内する。 The coil 1 of the coil body C has a plurality of wires 16 arranged on the second side portion 12 of the non-working side.

The base 2 is provided with at least one cooling channel 22. Any one of the cooling channels 22 extends along the axial direction of the base 2.

図９に示すように、実際に使用する際は、本実施形態のリニアモータコイルアセンブリ構造に、磁石軌道構造Ｄを組み合わせ、一般のコアレスリニアモータのコイルアセンブリＡ構造は、ベース２の熱伝導率が非常に高いアルミニウム合金からなるものがほとんどである。熱伝導率は、Ｑ＝−ＫＡ（ｄＴ／ｄＸ）の数式から得られる。この数式中、Ｑは熱流束値を表し、Ｋは熱伝導率を表し、Ａは接触面積を表し、ｄＴ／ｄＸは温度勾配を表す。このように、コイル１と、ベース２の挿着溝２１の内壁とが接触する面積を増大させ、放熱速度を向上させることができる。 As shown in FIG. 9, in actual use, the linear motor coil assembly structure of this embodiment is combined with a magnet track structure D, and the coil assembly A structure of a general coreless linear motor is based on the thermal conductivity of the base 2. Most of these are made of an aluminum alloy having a very high value. The thermal conductivity is obtained from the formula Q = −KA (dT / dX). In this equation, Q represents the heat flux value, K represents the thermal conductivity, A represents the contact area, and dT / dX represents the temperature gradient. Thus, the area where the coil 1 and the inner wall of the insertion groove 21 of the base 2 are in contact can be increased, and the heat dissipation rate can be improved.
本実施形態のリニアモータコイルアセンブリ構造は、複数のワイヤ１６をコイル１の非作用辺の第２の側部１２に配置し、コイル体端部１８のコイルの非作用辺の第２の側部１２をコイル体端部１８のコイル１の直線作用辺１０に巻き付けるとともに、ベース端部２３に樹脂封止膜３の外部ケーブルＢを挿入して接続し、コイル１の非作用辺の第１の側部１１をワイヤ１６に配置することにより、コイル１の非作用辺の第１の側部１１の空間を形成し、コイル１の非作用辺の第１の側部１１に、交互に折り曲げた第１の折り曲げ部１３を形成して表面積を増大させ、ベース２の挿着溝２１の内壁の接触面積を増大させ、放熱速度を向上させることができる。また、第１の折り曲げ部１３には、必要に応じて内側へ折り曲げて第２の折り曲げ部１４を形成し、コイル１とベース２の挿着溝２１の内壁とが接触する面積を増大させ、放熱速度を向上させる。コイル１は、複数の固定子コイル１７からなってもよい。各固定子コイル１７は、第１の折り曲げ部１３で分岐させ、その断面を複数の分岐状にすることにより、ベース２の接触面積を増大させ、放熱速度を向上させることができる。 In the linear motor coil assembly structure of the present embodiment, a plurality of wires 16 are arranged on the second side 12 of the non-working side of the coil 1, and the second side of the non-working side of the coil at the coil body end 18. 12 is wound around the linearly acting side 10 of the coil 1 at the coil body end 18, and the external cable B of the resin sealing film 3 is inserted and connected to the base end 23 to connect the first non-acting side of the coil 1. By arranging the side portion 11 on the wire 16, a space of the first side portion 11 of the non-working side of the coil 1 is formed, and the first side portion 11 of the non-working side of the coil 1 is alternately bent. The first bent portion 13 can be formed to increase the surface area, increase the contact area of the inner wall of the insertion groove 21 of the base 2, and improve the heat dissipation rate. Further, the first bent portion 13 is bent inward as necessary to form a second bent portion 14 to increase the area in which the coil 1 and the inner wall of the insertion groove 21 of the base 2 are in contact with each other. Improve heat dissipation rate. The coil 1 may be composed of a plurality of stator coils 17. Each stator coil 17 is branched at the first bent portion 13 and its cross section is formed into a plurality of branches, whereby the contact area of the base 2 can be increased and the heat dissipation rate can be improved.
ベース２は、冷却チャネル２２により表面と空気との熱対流を加速させることによりベース２の温度を下げ、ベース２の挿着溝２１の内壁とコイル１の接触面積との間を適切な温度勾配に保持し、コイル１の放熱速度を向上させる。ユーザは、ベース２の形状に応じ、第１の折り曲げ部１３の断面形状を逆Ｖ字状、逆Ｙ字状、逆Ｔ字状又は複数に分岐して互いに位置がずれた状態にしてもよい。また、ベース２の表面と空気との熱対流を加速させて放熱速度を向上させるために、ベース２上に配置する冷却チャネル２２の数を増やしてもよい。 The base 2 lowers the temperature of the base 2 by accelerating the thermal convection between the surface and air by the cooling channel 22, and an appropriate temperature gradient is provided between the inner wall of the insertion groove 21 of the base 2 and the contact area of the coil 1. To improve the heat dissipation rate of the coil 1. According to the shape of the base 2, the user may make the cross-sectional shape of the first bent portion 13 into an inverted V shape, an inverted Y shape, an inverted T shape, or a plurality of branched portions. . In addition, the number of cooling channels 22 arranged on the base 2 may be increased in order to accelerate the heat convection between the surface of the base 2 and the air and improve the heat dissipation rate.
コイル体Ｃが含む複数のコイル１は、ワイヤが巻き付けられ、折り曲げて形成するため、正確に成形することが困難である上、コイル体Ｃをベース２の挿着溝２１内に接続し、樹脂封止膜３を注入する際、ベース２の挿着溝２１の表面に接触すると、その絶縁性は、コイル１のワイヤ上の絶縁層の絶縁性しか有しなかった。そのため、絶縁性を高めるために、上述のベース２の挿着溝２１の表面に絶縁薄膜２４（図８を参照）を形成してもよい。絶縁薄膜２４は、注入用樹脂、絶縁コーティング、ワニス、ＰＩ絶縁テープ、電気絶縁紙などの材料からなり、注入、めっき、塗布、接着又は載置などの方式により、ベース２の挿着溝２１の表面へ付着した後、コイル体Ｃを結合させ、コイル１とベース２との絶縁性を向上させてもよい。また、この絶縁薄膜２４は、放熱効果を高めるために、厚さを１ｍｍより小さくしてもよい。 Since the plurality of coils 1 included in the coil body C are formed by winding and bending a wire, it is difficult to accurately form the coil 1, and the coil body C is connected to the insertion groove 21 of the base 2, and resin When injecting the sealing film 3, when it contacts the surface of the insertion groove 21 of the base 2, the insulating property is only that of the insulating layer on the wire of the coil 1. Therefore, an insulating thin film 24 (see FIG. 8) may be formed on the surface of the insertion groove 21 of the above-described base 2 in order to improve the insulation. The insulating thin film 24 is made of a material such as injecting resin, insulating coating, varnish, PI insulating tape, electrical insulating paper, and the like, and the insertion groove 21 of the base 2 is formed by a method such as injection, plating, coating, adhesion, or placement. After adhering to the surface, the coil body C may be coupled to improve the insulation between the coil 1 and the base 2. Further, the insulating thin film 24 may have a thickness smaller than 1 mm in order to enhance the heat dissipation effect.
