ル導線端部の処理の自動化を容易に行うことができる。According to each of the above embodiments, the coil conductor forming the coil can be guided to the connection position without being connected in the middle. Therefore, there is no need to perform an operation of connecting the coil conductors in the middle, and it is possible to prevent disconnection of the joint due to an operation failure. In addition, since the coil conductors of each phase are placed in dedicated grooves and can be separated and held from other phases, insulation between the phases is ensured. In addition, there is no need to put the coil conductor in the insulating tube or insert insulating paper between the phases for insulation, thereby simplifying the operation. Further, since the movement for placing the coil conductor in the groove is separated in the axial direction and the circumferential direction of the electric motor, the operation is simplified. Further, the simplification of the operation as described above makes it possible to easily automate the processing of the end portion of the coil conductor.
