Abstract
A production method of a rotor in which a lower layer slot insulator is held at a slot insulator holding portion of a combining jig, a lower layer coil bar is inserted into a coil inserting path of the combining jig and is combined integrally with the lower layer slot insulator by being pushed by a first coil inserting arrow and thereafter, set to inside of a coil integrating path of a coil holding member. The coil holding member is attached to a coil inserting device along with an armature core. The lower layer slot insulator and a lower layer coil trunk are integrally inserted into a slot of the armature core by pushing the lower layer coil bar set to inside of the coil integrating path. The upper layer coil trunk and the lower layer coil trunk may be formed integrally with respective coil arms as a single coil bar.
