ある。[Detailed description of the invention] The present invention aims to improve the workability of installing the spark-quenching element in a small DC motor in which a ring-shaped spark-quenching element is attached to a commutator to eliminate sparks generated between slits. The purpose is to eliminate problems when connecting the rotor winding to the commutator and improve quality.

ンスを崩すという欠点があった。Conventionally, in this type of small DC motor, as shown in FIG. The rotor assembly is constructed by soldering a ring-shaped spark quenching element 6' to the commutator segment 5, but there is something between the spark quenching element 6 and the commutator segment 5 that regulates the radial position. Not only does it take a lot of time to install the rotor, but it also has the disadvantage that the installation varies greatly over time, causing the rotor to become unbalanced.

合を生じる場合があった。Furthermore, when soldering the commutator segment 5 of the rotor winding 2 to the riser part 5a, the solder flows to the sliding part between the commutator segment 5 and the brush, causing a problem in the contact between the brush and the commutator. There was a case.
本考案は上記従来の欠点を除去するもので、以下本考案

Furthermore, it is of great practical value as it is possible to improve the quality of the connection between the commutator segments and the rotor windings.
