Abstract
An armature of a rotary electric machine composed of an armature core, an armature winding and a shaft is manufactured in the following manner. A conductor bar including plural conductors connected in line is formed, and each conductor is cut out from the conductor bar. The conductor in a straight shape is inserted into each slot of the armature core, and then both side portions of the conductor are bent at substantially right angle so that the side portions are positioned along axial end surfaces of the armature core. The side portions are further skewed and electrically connected to form the armature winding. An outer surface of the side portions circularly arranged on the axial end surface of the armature core is used as a commutator surface.
