Description
【考案の詳細な説明】 この考案は小型直流モータに関するものである。[Detailed explanation of the idea] This invention relates to a small DC motor.
従来の小型直流モータは、ブラシ・整流子セグメント間
の火花発生を抑制するために、第１図に示すように、整
流子セグメント１〜３間にそれぞれ抵抗器４〜６を接続
してサージ電圧を吸収していた。In order to suppress the generation of sparks between brushes and commutator segments, conventional small DC motors connect resistors 4 to 6 between commutator segments 1 to 3, respectively, to suppress surge voltage. was absorbing.
このような従来の小型直流モータは、抵抗器４〜６のは
んだづけ工程が必要であるから製造が容易でなく、抵抗
器４〜６のスペースが必要であるから形状寸法が大きく
なり、抵抗器４〜６に流れる電流がすべてモータ・ロス
になるという問題があった。Such a conventional small DC motor is not easy to manufacture because it requires a soldering process for the resistors 4 to 6, and the shape and dimensions are large because the resistors 4 to 6 require space. There was a problem in that all of the current flowing through the motors 6 to 6 became motor loss.
したがって、この考案の目的は、製造が容易で、小型化
を促進することができ、モータ・ロスの少い小型直流モ
ータを提供することである。Therefore, an object of this invention is to provide a small DC motor that is easy to manufacture, can promote downsizing, and has less motor loss.
要約すれば、この考案は、抵抗線をモータ巻線と一緒に
ロータ磁極に巻回し、この抵抗線の両端を隣接する整流
子セグメントに接続する。In summary, the invention winds a resistance wire around the rotor poles together with the motor windings, and connects both ends of this resistance wire to adjacent commutator segments.
第２図はこの考案の小型直流モータの一実施例の要部斜
視図である。FIG. 2 is a perspective view of essential parts of an embodiment of the small DC motor of this invention.
すなわち、Ｎｉ−Ｃｕ抵抗線７がモータ巻線８とともに
ロータ磁極９に巻回されている。That is, the Ni--Cu resistance wire 7 is wound around the rotor magnetic pole 9 together with the motor winding 8.
この抵抗線７およびモータ巻線８は第３図に示すように
相互に隣接する整流子セグメント１０に接続される。The resistance wire 7 and the motor winding 8 are connected to mutually adjacent commutator segments 10 as shown in FIG.
そのため、モータ巻線８に発生するサージ電圧が抵抗線
７の抵抗器で吸収され、抵抗線７に流れる電流がトルク
の発生に寄与し、抵抗体のスペースが不要となるため全
体が小型となる。Therefore, the surge voltage generated in the motor winding 8 is absorbed by the resistor of the resistance wire 7, the current flowing through the resistance wire 7 contributes to the generation of torque, and the space for the resistor is not required, so the overall size is reduced. .
以上のように、この考案の小型直流モータは、火花吸収
用の抵抗をロータ磁極に巻回しているため、つぎのよう
な効果を奏する。As described above, the small DC motor of this invention has the following effects because the spark absorbing resistor is wound around the rotor magnetic poles.
１ 抵抗線をモータ巻線と同じように巻回することがで
きるため、製造が容易となる。1. Manufacturing is easy because the resistance wire can be wound in the same way as the motor winding.
２ スペースが不要となり、小型化が可能となる。2 Space is not required and miniaturization is possible.
３ 抵抗線に流れる電流がトルク発生に寄与するため、
モータ・ロスが少くなる。3. Since the current flowing through the resistance wire contributes to torque generation,
Motor loss is reduced.
