Description
【発明の詳細な説明】 この発明は直流モーターの整流装置の改良に関する。[Detailed description of the invention] This invention relates to improvements in rectifying devices for DC motors.

で、コイルとの間で短絡電流が充分流れず大きなサージ
電圧が発生して火花が発生し易いという欠点がある。In a rectifying device in which a brush B is brought into elastic contact with a commutator D having a slit S between segments g and g as shown in FIG.
A part of the brush B falls into the slit S, causing the brush to bounce and cause chatter, which can easily damage the pegs and commutator. In a rectifying device in which a brush B is brought into elastic contact with a commutator D in which an insulator C is embedded in a slit S,
The brush will no longer bounce, but on the other hand, there will be no time to short circuit between the segments, or the short circuit time will be very short, so a short circuit current will not flow between the coils and a large surge voltage will occur, causing sparks. It has the disadvantage of being easy.

分を摺動するように弾接したものである。In view of the above, the present invention provides segment g as shown in the third figure.
, g, and a commutator ○ in which an insulator C is partially buried in the slit S, one branch piece bl covers the slit S, and the other branch piece b2 is an insulator. The part C is in elastic contact so as to slide.

のない整流装置が簡単に得られる有用性がある。Therefore, according to the present invention, one side of the branch brush slides on the slit portion and the short-circuit current changes gently between the segments, suppressing the generation of large surge voltage and preventing the generation of sparks. By sliding on the insulating material part, the brush does not fall down and chatter due to bouncing can be prevented, the brush and commutator are not damaged and their lifespan can be extended, and a rectifier without radio wave interference can be easily obtained. be.
尚、平板型整流子の場合刷子は周速の速い外周部分がバ
ウンドし易いので、周速の速い外周部に絶縁物を埋設す
るのが効果的である。In the case of a flat plate type commutator, since the outer peripheral portion of the brush where the circumferential speed is high is likely to bounce, it is effective to embed an insulator in the outer peripheral portion where the peripheral speed is high.
