Abstract

PURPOSE: To reduce abration of the commutator section while stabilizing the contact resistance between the brush and the commutator employing an alloy brush made of silver or silver alloy containing a specified amount of Nb.
CONSTITUTION: A brush made of an alloy is used. The alloy is produced by adding 2 to 8% by weight of Nb to silver or a silver alloy composed of silver and one or more kinds of Cu, In, Cd and Mn as additives. This can check increase in the contact resistance between the brush and commutator along with a higher wear resistance.
