Abstract
Abstract Displayed herein is a method of making an electrical connector to an electrical brush (1) wherein at least one electrical connector (3,4) is welded to one or more faces (2) of an electrical brush (1) that is formed of a weldable material and a flexible current shunt (6) is attached to the connector (3, 4); in a preferred method, the connector (3, 4) is resistance welded to the brush and the shunt (6) is resistance welded to the connector (3, 4) in the same operation.
