この考案は、小型電動機における速度制御素子
の取付け構造の改良に関する。[Detailed Description of the Invention] This invention relates to an improvement in the mounting structure of a speed control element in a small electric motor.
従来より、モータ本体の底部に電気的速度制御
装置を配し、これを外ケースに格納してなるもの
は公知である。 Conventionally, it is known that an electric speed control device is disposed at the bottom of a motor body and is housed in an outer case.
ところで、このような構成において、最近では
薄型傾向のため、第１図に示すように給電制御用
トランジスタあるいは、極く最近では、この給電
制御用トランジスタを含む集積回路素子などの比
較的大きい速度制御素子１をモータケース２の外
側面に配してなるものが知られている。 By the way, in such a configuration, there is a recent tendency to make it thinner, so as shown in FIG. A motor in which the element 1 is disposed on the outer surface of a motor case 2 is known.
しかしながらこのようにした場合、速度制御素
子１がモータケース２の側面に配されているの
で、磁気ノイズを極端にきらう音響用機器に用い

てふせごうとするとき、このケイ素鋼板の巻付け
ができないという問題点が発生する。したがつ
て、このような場合においては第２図に示すよう
に、モータケース２の外側面にケイ素鋼板３を巻
回して磁気ノイズをふせぐようにすると共に、こ
れを外ケース４に格納し、速度制御素子１はこの
外ケース４の外側面に配するようにしている。 However, in this case, the speed control element 1 is placed on the side of the motor case 2, so when used in audio equipment that is extremely sensitive to magnetic noise, silicon steel plates are usually placed around the side of the motor to cover it. A problem arises in that the silicon steel plate cannot be wrapped when the steel plate is used. Therefore, in such a case, as shown in FIG. 2, a silicon steel plate 3 is wound around the outer surface of the motor case 2 to prevent magnetic noise, and the silicon steel plate 3 is stored in the outer case 4. The speed control element 1 is disposed on the outer surface of the outer case 4.
ところが、こんどは、速度制御素子１が外ケー
ス４の外側面より外方に出つぱつているため、セ
ツトに実装する場合、この速度制御素子１が当つ
てしまう場合が出て、取付け位置を選ばねばなら
ず、販路も限定されたものとなる欠点が生じてし
まう。しかも、このモータを不用意に落下させた
りすると、この速度制御素子１が最先きに破壊さ
れてしまう。 However, since the speed control element 1 protrudes outward from the outer surface of the outer case 4, when it is mounted in a set, the speed control element 1 may come into contact with it, making it difficult to adjust the mounting position. This has the disadvantage of having to make a selection and limiting sales channels. Moreover, if this motor is dropped carelessly, this speed control element 1 will be destroyed first.
この考案は、上記のような欠陥を、ケースの外
側面に設けた凹所に速度制御素子の本体部を収納
させるという簡単な構成により解決したものであ
る。 This invention solves the above-mentioned defects with a simple structure in which the main body of the speed control element is accommodated in a recess provided on the outer surface of the case.
以下、この考案の構成を図面に示す実施例にも
とづいて説明する。 The configuration of this invention will be explained below based on the embodiments shown in the drawings.
第３図において、モータケース２２の側面に切
抜きからなる変形防止部５を設け、この変形防止
部５に連続した下方をプレスなどにより内部に押
しこんで凹所６を設ける。この凹所６に、ブラシ
基板７に植設した前記速度制御素子１の本体部１
ａ……を収納するのである。 In FIG. 3, a deformation preventing portion 5 made of a cutout is provided on the side surface of the motor case 22, and a concave portion 6 is provided by pressing the lower portion continuous with the deformation preventing portion 5 into the interior using a press or the like. The main body 1 of the speed control element 1 is implanted in the brush substrate 7 in this recess 6.
It stores a...
このように凹所６の上方に切抜きからなる変形
防止部５を設けると、凹所６を成型するときの応
力変形が上面の軸受部に加わるおそれがなく、凹
所６の成型が容易にできる。 By providing the deformation prevention part 5 made of a cutout above the recess 6 in this way, there is no risk of stress deformation being applied to the bearing part on the upper surface when molding the recess 6, and the molding of the recess 6 can be facilitated. .
この凹所６の成型によつてできる内側面の凸所
８は、第４図に示すようにＣ型の界磁用マグネツ
ト９，９の位置決めに利用する。 A convex portion 8 on the inner surface formed by molding the recess 6 is used for positioning C-shaped field magnets 9, 9, as shown in FIG.
このようにした場合、界磁用マグネツト９，９
の固定が容易にでき、ブラシ基板７に配した突起
などによつて、Ｃ型の界磁用マグネツト９，９は
接着を不要ならしめることもできる。 In this case, the field magnets 9, 9
The C-shaped field magnets 9, 9 can be easily fixed, and the C-shaped field magnets 9, 9 can be made unnecessary to be bonded by the protrusions arranged on the brush substrate 7.
また、このブラシ基板７には、第３図に示すよ
うに他の速度制御素子１１……と共に一対のブラ
シ１２，１２が植設されている。図中、１３はこ
のブラシ基板７を支持するエンドブラケツトであ
り、前記ケース２２の開口縁にかしめなどによつ
て取付けられている。 Further, as shown in FIG. 3, a pair of brushes 12, 12 are implanted on this brush substrate 7 together with other speed control elements 11. In the figure, reference numeral 13 denotes an end bracket that supports the brush base plate 7, and is attached to the opening edge of the case 22 by caulking or the like.
このようにすると、ブラシ基板７と電子ガバナ
用基板が一体化されるので軸方向の姿勢を低くす
ることができる。 In this way, the brush substrate 7 and the electronic governor substrate are integrated, so that the posture in the axial direction can be lowered.
上記は外ケースを有しないものについて述べた
が、第２図想像線で示すように磁気ノイズのうる
さい音響用セツトに用いるために、ケイ素鋼板３
を巻回してこれらを外ケース４に格納して用いる
場合には、速度制御素子１の本体部が出つぱつて
いないため、不用意にモータ本体を落下させて
も、速度制御素子が破損してしまうおそれがな
く、ケイ素鋼板３の巻回作業が容易となるし、外
観もコンパクトになる利点もある。 The above description is about the one without an outer case, but as shown by the imaginary line in Figure 2, a silicon steel plate 3
When used by winding the motor and storing them in the outer case 4, the main body of the speed control element 1 is not protruding, so even if the motor main body is accidentally dropped, the speed control element will not be damaged. There is no fear that the silicon steel plate 3 will be damaged, the work of winding the silicon steel plate 3 becomes easy, and there is also the advantage that the appearance becomes compact.
また、第５図に示すようにＣ型の界磁用マグネ
ツト９，９を用いる場合には、凹所６は対向に設
けてもよく、このようにした場合は、他方の凹所
に電解コンデンサ等の比較的大型の他の速度制御

て界磁が急激になくなることによつておきるコギ
ングも緩和される効果もある。 Further, as shown in FIG. 5, when C-type field magnets 9, 9 are used, the recesses 6 may be provided oppositely, and in this case, an electrolytic capacitor is placed in the other recess. It is also possible to accommodate other relatively large speed control circuit elements such as, etc., and there is also the effect of alleviating the cogging caused by the sudden disappearance of the field in this part.
