Abstract
A method of linking commutator bars of a commutator for a motor wherein N is the number of magnetic poles of the motor and N is an even integer greater than 2. The method include a) arranging a plurality of commutator bars to be generally equally spaced in a circular arrangement to define the commutator, each commutator bar having a tang extending therefrom, b) contacting an end of a continuous, insulated conductive member to a tang, c) moving the member to contact a second tang which is disposed at an angle of 720°/N from the previously contacted tang to form a link, and when N is greater than four, repeating this step until N/2−1 links are created, d) moving the member to contact a tang which is immediately adjacent to the second tang contacted in step (c) such that the member defines a bridging portion between the adjacent tangs, e) repeating steps (c) and (d) and until all tangs have been contacted by the member, and f) cutting the bridging portion between adjacent tangs.
