PURPOSE:To improve the insulating characteristic by coating resin curing catalyst before coating a main insulating layer over axial length of a core slot at least at both side faces of a coil conductor unit, thereby accelerating the hardening of the resin and preventing the leakage. CONSTITUTION:Strand conductors 1 coated with strand insulators 2 are wound in quintuple in the depthwise direction of a slot and adjacently in two rows in the circumferential direction. Then, a resin curing catalyst 12 is wound on the entire periphery of a coil conductor unit 5, the base material of a main insulating layer 6 is then coated on the periphery of the coil conductor unit 5 coated with the catalyst 12, a semiconductor layer 11 is coated on the outer peripheral surface to form coil units 7A, 7B. The units 7A, 7B are inserted into the slot 4 of the core 3, a wedge 9 is driven into, the entirety is filled in a resin tank and resin is then immersed. |
