摘要

A method of manufacturing a set of brushes for use in a small dynamoelectric machine that is provided with a flat collector, the brush assembly comprising a brush holder and a plurality of brushes that are mounted on the support so that they are electrically insulated of others and are made of sheet metal and each has at least one brush element in the form of a metal leaf spring, the free ends of the leaf springs being in contact with the manifold, characterized in that the method comprises the following steps in the manufacture of the brush assembly: 1. Manufacture an intermediate sheet metal product comprising the brushes in a relative arrangement corresponding to their final relative arrangement in the finished machine, and connecting parts that connect the brushes to each other, firmly joining said intermediate product to the brush holder, and 3. Breaking the connexions between the brushes cutting them and/or removing all or part of the aforementioned connecting parts. (Machine-translation by Google Translate, not legally binding)
