Description
【０００１】[0001]
本考案は、ＦＤＤやカセットデッキ、最近ではＣＤ等の回転伝達機構に用いる ブラシレスモータの特にステータ構造に関するものである。 The present invention relates to a stator structure of a brushless motor used for a rotation transmission mechanism such as an FDD, a cassette deck, and recently a CD.
【０００２】[0002]
近年、ＦＤＤやカセットデッキ，ＣＤ等の機器は薄型，高性能化の要望が多く なり、それに使用されるモータも薄型のブラシレスモータが採用されつつある。 In recent years, there have been increasing demands for thinner and higher-performance devices such as FDDs, cassette decks, and CDs, and thin-type brushless motors are being adopted as the motors used for such devices.
【０００３】 以下、図面を参照しながら上記従来のブラシレスモータのステータ構造の一例 について説明する。An example of the conventional stator structure of the brushless motor will be described below with reference to the drawings.
【０００４】 図２は従来のブラシレスモータのステータ構造の断面図を示すものである。図 ２において６は電気的磁気的ノイズを遮蔽するための底板であり、中央部に樹脂 部材７が一体成形されている。鉄心２にインシュレータ１を介して駆動巻線３が 巻装された電機子と駆動や制御に必要な回路素子が実装されたプリント基板８と が前記インシュレータ１に圧入された結線ピン５を介して結合されている。そし て前記樹脂部材７に鉄心２を溶着にて固定し、ブラシレスモータのステータ構造 を構成している。FIG. 2 is a cross-sectional view of a conventional brushless motor stator structure. In FIG. 2, reference numeral 6 is a bottom plate for shielding electric and magnetic noises, and a resin member 7 is integrally molded in the central portion. An armature in which a drive winding 3 is wound around an iron core 2 via an insulator 1 and a printed board 8 on which circuit elements necessary for driving and control are mounted are connected via a connecting pin 5 press-fitted into the insulator 1. Are combined. Then, the iron core 2 is fixed to the resin member 7 by welding to form a brushless motor stator structure.
【０００５】[0005]
しかしながら上記の従来の構造では、底板６と電機子との間にプリント基板８ を有し薄型には不利であり、たとえ金属プリント基板を使用したとしても結線ピ ン５との結合が鉄心２の磁極と磁極の間いわゆるスロット内部で処理しなければ ならなく組立が困難であった。また結線ピン５を磁極外周部に保持するためには インシュレータ樹脂の肉厚をかなり厚くする必要があってモータの薄型には適さ ないという問題点を有していた。 However, in the above-mentioned conventional structure, the printed circuit board 8 is provided between the bottom plate 6 and the armature, which is disadvantageous in thinness. Even if a metal printed circuit board is used, the connection with the connection pin 5 is not achieved by the iron core 2. Assembly between the magnetic poles was difficult because it had to be processed inside the so-called slot. Further, in order to hold the connecting pin 5 on the outer peripheral portion of the magnetic pole, the insulator resin needs to be made considerably thick, which is not suitable for thin motors.
【０００６】 本考案は上記従来の問題点を解決するもので、従来の性能を維持し容易に薄型 化出来るブラシレスモータのステータ構造を提供することを目的とする。The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a stator structure of a brushless motor that can maintain the conventional performance and can be easily thinned.
【０００７】[0007]
この目的を達成するために本考案のブラシレスモータのステータ構造は、鉄心 の磁極中央部先端に貫通穴あるいは勃穴を設け、インシュレータ樹脂にて絶縁し 、結線ピンを配設し、金属プリント基板と結合させたものである。 In order to achieve this purpose, the stator structure of the brushless motor of the present invention has a through hole or a sharp hole at the tip of the magnetic pole of the iron core, is insulated with an insulator resin, is provided with a connecting pin, and is provided with a metal printed circuit board. It is a combination.
【０００８】[0008]
この構成によって、底板と電機子との間にプリント基板を配設する必要がなく なる。 With this configuration, it is not necessary to dispose a printed board between the bottom plate and the armature.
【０００９】[0009]
以下本考案の一実施例について、図面を参照しながら説明する。 An embodiment of the present invention will be described below with reference to the drawings.
【００１０】 図１は本考案の実施例におけるブラシレスモータのステータ構造の断面図を示 すものである。図１において、１は熱可塑性樹脂からなるインシュレータであり 、磁極中央部先端に貫通穴を有した鉄心２と一体に成形され駆動巻線３が巻かれ ている。貫通穴中央部には樹脂を介して結線ピン５が圧入されて外周方向に９０ °に折り曲げられていて駆動巻線３の巻始めあるいは巻終わりをからげ半田処理 し、回路素子を実装した金属プリント基板に半田付けされている。FIG. 1 is a sectional view of a stator structure of a brushless motor according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes an insulator made of a thermoplastic resin, which is integrally formed with an iron core 2 having a through hole at the tip of the magnetic pole center part and around which a drive winding 3 is wound. A connecting pin 5 is press-fitted through a resin in the center of the through hole and is bent at 90 ° in the outer peripheral direction. The winding start or the winding end of the drive winding 3 is entangled and soldered to form a metal on which a circuit element is mounted. Soldered to the printed circuit board.
【００１１】 なお実施例において鉄心２の磁極中央部先端穴を貫通穴としたが積層鉄心枚数 の途中まで穴をあけた勃穴構造としても良い。また、インシュレータを鉄心と一 体成形としたが、インシュレータの上下を分離し鉄心に組み込み巻線した構造と してもよいことは言うまでもない。又結線ピンは圧入としたがインシュレータと 同時に一体成形してもよいことは言うまでもない。In the embodiment, the hole at the tip of the magnetic pole center portion of the iron core 2 is used as a through hole, but a hole structure may be used in which a hole is formed halfway through the number of laminated iron cores. Further, although the insulator is integrally formed with the iron core, it is needless to say that the insulator may be separated into upper and lower parts and incorporated into the iron core and wound. Further, although the connection pin is press-fitted, it goes without saying that it may be integrally formed with the insulator at the same time.
【００１２】[0012]
【考案の効果】 以上のように本考案は、鉄心の磁極中央部先端に穴を設けその中央部に結線ピ ンをインシュレータと同様の樹脂にて絶縁し固定することにより結線ピン保持に 必要な樹脂の肉厚がいらなくなり、また金属プリント基板と容易に結合でき従来 の底板と電機子との間のプリント基板がいらなくなって薄型のブラシレスモータ が実現できる。As described above, according to the present invention, a hole is formed at the tip of the center of the magnetic pole of the iron core, and the connecting pin is insulated and fixed to the center with the same resin as that of the insulator. A thin brushless motor can be realized because the resin does not need to be thick and the printed board between the conventional bottom plate and the armature can be easily connected because it can be easily combined with the metal printed board.
