Description
【考案の詳細な説明】 本考案は小型モータに関するものである。[Detailed explanation of the idea] The present invention relates to a small motor.
従来に釦いて時計等の分野でステータを一体にコ字状に
形成した例があるが、ステータが１枚の薄板力らなるた
めに反りが生じ易く、ステータ磁極部の寸法精度並びに
ロータとの相対的位置精度が低下し、ロータの円渭な回
転を為し得なくなるなどの不都合を生じることがあった
。Conventionally, there have been examples in the field of buttons and watches in which the stator is integrally formed into a U-shape, but since the stator is made up of a single thin plate, it tends to warp, and the dimensional accuracy of the stator magnetic poles and the relationship with the rotor are difficult. In some cases, the relative positional accuracy is lowered, resulting in inconveniences such as the rotor not being able to rotate circularly.
本考案は、簡単な構成で上記不都合を解消するようにし
たものであって、以下その一実施例について説明する。The present invention is intended to solve the above-mentioned disadvantages with a simple configuration, and one embodiment thereof will be described below.
第１図および第２図において、ステータ１はパーマロイ
、鋼、硅素鋼板などの高透磁率材料の１板の薄板からコ
字状に打抜き形成したものである。In FIGS. 1 and 2, a stator 1 is formed by stamping a U-shaped thin plate of a high magnetic permeability material such as permalloy, steel, or silicon steel plate.
平行に延伸する二つの脚片１ａ、１ｂの各先端にはステ
ータ磁極部１ｃ、１ｃが相対向するように形成してあり
、一方の脚片１ａにボビン２を介してコイル３が巻回さ
れている。Stator magnetic pole portions 1c, 1c are formed at the ends of two leg pieces 1a, 1b extending in parallel so as to face each other, and a coil 3 is wound around one leg piece 1a via a bobbin 2. ing.
ボビン２は合成樹脂例えばＡＢＳ樹脂等にて形成したも
のであって、脚片１ａに貫通装置しである。The bobbin 2 is made of synthetic resin, such as ABS resin, and has a penetrating device in the leg piece 1a.
ステータ磁極部１ｃ側のボビン２のつば部２ａには、そ
の左側のつば部２ｂに比して上方へ長く延伸した延出部
２’ａが一体に形成してあり、との延出部２’ａに開設
しである透孔２ｃを他方の脚片１ｂが挿通されている。The collar portion 2a of the bobbin 2 on the side of the stator magnetic pole portion 1c is integrally formed with an extension portion 2'a extending upwardly longer than the collar portion 2b on the left side thereof. The other leg piece 1b is inserted through the through hole 2c opened at 'a'.
これによって両脚片１ａ、１ｂの先端のステータ磁極部
１ｃ、１ｃが反りによって変位することを規制され、ス
テータ磁極部１ｃ、１ｃが所定の位置に保持される。This prevents the stator magnetic pole parts 1c, 1c at the tips of the leg pieces 1a, 1b from being displaced due to warping, and the stator magnetic pole parts 1c, 1c are held at predetermined positions.
さらにつば部２ａの下辺部から垂直にロータ支持板４が
一体に形成さ札ロータ支持板４の軸受５にてロータ６の
軸７の一端が回転自在に支承されている。Further, a rotor support plate 4 is integrally formed vertically from the lower side of the flange 2a, and one end of the shaft 7 of the rotor 6 is rotatably supported by a bearing 5 of the rotor support plate 4.
軸７の他端はこの例ではロータ支持板８の軸受９にて回
転自在に支承され、この支持板８が支持板４から一体に
突設された取付脚部１０にネジ止めされている。In this example, the other end of the shaft 7 is rotatably supported by a bearing 9 of a rotor support plate 8, and this support plate 8 is screwed to a mounting leg 10 integrally projecting from the support plate 4.
このように構成することによって、コ字状ステータ１の
ステータ磁極部１ｃ、１ｃの相対位置がボビン２のつば
部２ａとそれと一対の延出部２’ａによって所定の精度
に保持されるから、反り等による位置ずれを生じること
がなく、な釦かつ振動等の外力が加わってもステータ磁
極部１ｃ、１ｃが変化することがないからその位置精度
に保たれる。With this configuration, the relative position of the stator magnetic pole parts 1c, 1c of the U-shaped stator 1 is maintained at a predetermined accuracy by the collar part 2a of the bobbin 2 and the pair of extension parts 2'a. There is no positional shift due to warping, etc., and the positional accuracy is maintained because the stator magnetic pole parts 1c, 1c do not change even if an external force such as a button or vibration is applied.
しかもステータ磁極部１ｃ、ｌｃの相対位置を保持する
つば部２ａと一体のロータ支持板４によってロータ６の
軸７を支持しているから、ステータ磁極部１ｃ、１ｃと
ロータ６の相対位置関係も高精度に保持できる。Moreover, since the shaft 7 of the rotor 6 is supported by the rotor support plate 4 which is integrated with the flange 2a that maintains the relative positions of the stator magnetic pole parts 1c, lc, the relative positional relationship between the stator magnetic pole parts 1c, 1c and the rotor 6 is also controlled. Can be held with high precision.
したがって外部衝撃等に対しても動作が安定し、ロータ
の回転を円渭になすことができる。Therefore, the operation is stable even against external shocks, and the rotor can rotate in a circular manner.
また構成も簡単であるから組立の作業性を損うことがな
いなど、実用上の効果は誠に著大である。Furthermore, since the structure is simple, the workability of assembly is not impaired, and the practical effects are truly significant.
