コミテータ及びカーボンブラシを有し、かつ、バネ性を有するブラシアームに前記カーボンブラシを取り付け、このカーボンブラシが前記コミテータに摺動接触し、カーボンブラシの幅がコミテータ片間の溝の幅より大である有ブラシ直流モータにおいて、
前記カーボンブラシが第１のコミテータ片から離れるときに遮断されるカーボンブラシと前記第１のコミテータ片の間の電流値と、前記第１のコミテータ片に隣接する第２のコミテータ片とカーボンブラシの間に流れる電流値との間に差電流が生じる、
ことを特徴とする有ブラシ直流モータ。 Having a commutator and carbon brushes, and attaching the carbon brushes in the brush arm having a spring property, the carbon brushes are in sliding contact with the commutator, the width of the carbon brushes large than the width of the grooves of the commutator pieces In a certain brush DC motor,
A current value between the carbon brush and the first commutator piece which is cut off when the carbon brush leaves the first commutator piece, and a second commutator piece adjacent to the first commutator piece and the carbon brush. A difference current occurs between the current value flowing in between,
A brushed DC motor characterized by that . 前記差電流に基づき、モータ回転位置に基づくパルスを出力して位置制御する用途に用いられる請求項１に記載の有ブラシ直流モータ。The brushed DC motor according to claim 1, wherein the brushed DC motor is used for position control by outputting a pulse based on a motor rotation position based on the difference current. 前記カーボンブラシの幅は、コミテータ片間の溝の幅よりも大きく、かつ溝の幅の１．４５倍以下である請求項１又は２に記載の有ブラシ直流モータ。The brushed DC motor according to claim 1 or 2, wherein a width of the carbon brush is larger than a width of a groove between the commutator pieces and is 1.45 times or less a width of the groove. 前記カーボンブラシは、ブラシアーム取付側から先端部に向けてブラシ幅を狭くし、かつ、この狭いブラシ幅の先端部において、コミテータに接触するよう構成した請求項３に記載の有ブラシ直流モータ。 4. The brushed DC motor according to claim 3 , wherein the carbon brush is configured such that a brush width is narrowed from a brush arm mounting side toward a tip portion, and the tip portion having the narrow brush width is in contact with a commutator . 前記先端部のブラシ幅の中央を、コミテータの位相中性ラインに一致させた請求項４に記載の有ブラシ直流モータ。 The brush DC motor according to claim 4 , wherein the center of the brush width of the tip portion is matched with the phase neutral line of the commutator.
