Abstract

PURPOSE: To obtain a commutator which is in stable contact with the brush, low in noise and has an excellent durability by impregnating grease of specific volumetric ratio for electric contact points into a sintered alloy composed of specific weight ratio of Ag, Cu, Ni, Sn.
CONSTITUTION: This commutator is manufactured by impregnating grease of 10∼ 25% in the volume percentage for electric contact points into sintered alloy which is composed of 1∼30% Cu, 1∼10% Ni, 1∼10% Su and residual Ag in the weight percentage. The commutator manufactured in this method is in stable contact with the brush, low in noise and has an excellent durability.
