ABSTRACT:
In a production method of a rotor, 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 together. Thereafter, the combined set is set in 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 coil trunk are integrally inserted into a slot of the armature core by pushing the lower layer coil bar in the coil integrating path. The lower layer coil trunk and an upper layer coil trunk may be formed integrally with respective coil arms as a single coil bar.
