Abstract

PURPOSE:To simplify the manufacture of the subject commutator bar as well as to increase the intensity of its riser by a method wherein the commutator bar and the riser section are punched out in a body from a narrow-stripped member having the section same as the commutator bar and then the riser section is bent and shaped. CONSTITUTION:A member, wherein the commutator bar 1 and a riser forming piece 5 are longitudinally formed in a body, is punched out from the narrow- stripped conductive member having the section same as the commutator bar 1. Then, after this riser forming piece 5 has been bent and set upright, it is shaped into a riser 6 by applying pressure to the direction of thickness. Through these procedures, the manufacture of the commutator bar having a riser is simplified, its manufacturing time is cut down, its strength is increased because the riser 6 and the commutator bar 1 are coupled in a body and also the size of the riser can be selected freely.
