A commutator bar () includes a body and first and second anchors disposed in spaced relation with each anchor and coupled to a proximal end of the body. A free end of the first anchor () extends in a direction towards the proximal end H of the body, and a free end of the second anchor () extends in a direction towards a distal end () of the body. Third and fourth anchors () and (), are disposed in spaced relation and each have one end coupled to a distal end of the body and a free end extending in a direction towards the proximal end of the body. Fifth and sixth anchors () and () each have one end coupled to the body at a location between the proximal and distal ends. A free end of the fifth anchor extends toward one side of the body and a free end of the sixth anchor extends toward the other side of body.

Robust commutator bar anchoring configuration with dove-tailed features

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&deg;/N from the previously contacted tang to form a link, and when N is greater than four, repeating this step until N/2&minus;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.
