この発明は扁平形回転電機の固定子として用い
られるマグネツト装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnet device used as a stator of a flat rotating electrical machine.
従来扁平形回転電機に用いられる固定子側マグ
ネツトとして環状をなしその正面に所定磁極を着
磁したものがある。ところが、このようなマグネ
ツトは回転電機内においてかなりのスペースを占
有するため回転電機の薄形化を図る上で極めて不
利である。 Conventionally, there is a stator-side magnet used in a flat rotating electric machine, which has an annular shape and has a predetermined magnetic pole magnetized on the front thereof. However, such a magnet occupies a considerable amount of space within the rotating electrical machine, which is extremely disadvantageous in making the rotating electrical machine thinner.
そこで、従来マグネツトの厚さ方向の寸法を有
効に利用すべく第１図に示すように例えば２個の
半環状マグネツト１，２を所定の間隙３をおいて
配置し、この間隙３中にブラシ４を設けたものが
ある。つまり、このようにするとマグネツト１，
２の厚さ方向のスペースにブラシ４が納められる
ので回転電機の薄形化に極めて有効である。 Therefore, in order to effectively utilize the dimension in the thickness direction of conventional magnets, for example, two semi-annular magnets 1 and 2 are arranged with a predetermined gap 3 in between, as shown in FIG. There is one with 4. In other words, if you do this, magnet 1,
Since the brush 4 can be accommodated in the space in the thickness direction of 2, this is extremely effective in making the rotating electric machine thinner.
しかしながら、このものはマグネツトが複数に
分割されるため組立工数が増しこのために多大の
手間を要し面倒である。またマグネツトの間隙中
に設けられるブラシの固定を別途考慮しなければ
ならず、仮にこの固定が充分でないとブラシが回
転子側の整流子に摺動する際大きな振動や摺動音
が発生する原因になることがあつた。 However, in this method, the magnet is divided into a plurality of parts, which increases the number of assembly steps, which requires a great deal of effort and trouble. In addition, it is necessary to separately consider how to fix the brushes installed in the gap between the magnets. If this fixation is not sufficient, large vibrations and sliding noises may occur when the brushes slide against the commutator on the rotor side. It happened that it happened.
この発明は上記欠点を除去するためなされたも
ので、マグネツト本体自体を環状に一体に形成す
ることにより組立が簡単で、しかもブラシ装置の
一部を埋設して一体固定することにより回転電機
の薄形化に大いに寄与し得るとともにブラシでの
振動および摺動音の発生をも防止できる扁平形回
転電機のマグネツト装置を提供することを目的と
する。 This invention was made in order to eliminate the above-mentioned drawbacks.The magnet body itself is integrally formed into an annular shape, so assembly is easy. Furthermore, by embedding a part of the brush device and fixing it integrally, it is possible to reduce the thickness of rotating electric machines. It is an object of the present invention to provide a magnet device for a flat rotary electric machine that can greatly contribute to the shape of the brush and also prevent vibration and sliding noise from occurring in the brush.
以下、この発明の一実施例を図面に従い説明す
る。 An embodiment of the present invention will be described below with reference to the drawings.
第２図において１１は環状のマグネツト本体
で、このマグネツト本体１１は正面円周方向を図
示極性（図示例では２極）に着磁している。 In FIG. 2, reference numeral 11 denotes an annular magnet main body, and the magnet main body 11 is magnetized in the front circumferential direction with the illustrated polarity (two poles in the illustrated example).
ここで、上記マグネツト本体１１は樹脂材料に
磁性材料を混入してなるものを成形加工により環
状に一体に形成したものである。 Here, the magnet main body 11 is made of a resin material mixed with a magnetic material and is integrally formed into an annular shape by molding.

ら、上記ブラシ装置１２はマグネツト本体１１の
成形過程で変形等を受けることなく磁極の境界部
分に当る所定位置にブラシ台１２１部分が埋設さ
れた形で一体的に固定される。この場合、ブラシ
１２２はマグネツト本体１１の中空部に導出され
ている。 Further, in the magnet main body 11, a part of the brush device 12 is embedded, for example, at the boundary between the magnetic poles. As shown in FIG. 3, this brush device 12 has a brush 122 supported on a resin brush stand 121. Here, the resin material forming the brush stand 121 is one that reacts at a higher temperature than the resin material of the magnet body 11. For this reason, the brush device 12 is integrally fixed with the brush stand 121 buried in a predetermined position corresponding to the boundary of the magnetic poles without being deformed during the molding process of the magnet body 11. In this case, the brush 122 is led out into the hollow part of the magnet body 11.

る。 However, if you do this, the magnet body 1
Since magnet 1 is formed from one piece without being divided, assembly can be greatly simplified compared to conventional magnets that are divided into a plurality of parts. In addition, since the brush stand 121 of the brush device 12 is embedded in the magnet body 11, the dimension in the thickness direction of the magnet body 11 can be effectively utilized, which greatly contributes to making the rotating electric machine thinner. The device 12 is embedded in the magnet main body 11 made of resin material as described above at the part that mainly includes the brush stand 121, and is firmly fixed by the elastic action peculiar to the resin. 1
It is also possible to prevent vibration and sliding noise from occurring when the commutator 22 slides on the commutator 14 on the rotor 13 side.

例えば上述では２極の場合を述べたがこれ以外の
極数の場合も同様に実施できる。 It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented with appropriate modifications within the scope without changing the gist.
For example, in the above description, the case of two poles has been described, but cases with other numbers of poles can also be implemented in the same manner.
