SMALL-SIZED MOTOR

摘要

PURPOSE:To prevent the surface of commutator segments from damaging by friction by mounting a member which impregnates ether alcohol having -OH group on part in a motor case. CONSTITUTION:A felt 14 is disposed near the side 3 of a commutatot on a bracket 12. The felt 14 has a linear carbon bond or a side chain, and a sole or a plurality of ether alcohols having a -OH group. The atmosphere in a motor case made of a motor housing 13 and a bracket 12 becomes vapor atmosphere with the ether alcohols.
