Abstract

PURPOSE: To obtain long servicable brush and to improve the following performance to the surface of commutator board, by composing the brush with sintered alloy and making the surface at the tip of the brush coarse to improve the adhesion with the alloy.
CONSTITUTION: The tip of brush 1 composed of sintered metallic powder is arched. A plurality of micro gaps 2 are formed on the surface. When the tip of the brush 1 or the arched outer circumference contacts and slides over the surface of commutator board 3, it produces heat and causes high temperature. Consequently slided alloy is formed there and partially buried into the gap 2 resulting in the imporvement of durability
