Embodiment 1
[0018] Such as figure 1 As shown, it is a schematic diagram of fixing the coil at the end of the stator. The large cone ring 7 is fixed at the end of the stator coil, and the resin rope is laid on the inner side of the large cone ring 7 to form the first resin rope layer 61. The lower layer wire rod 5 is arranged on the first On the resin rope layer 61, the ends of the lower wire rods 5 are half-wrapped in one layer with a polyethylene release tape, and the ends of the lower wire rods 5 are embedded in the first resin rope layer 61. Stoppers 9 are set between the lower wire rods 5, and epoxy resin potting glue 10 is poured between the lower wire rods 5 in the same phase and the separated phase. Epoxy resin potting glue 10 at the height of 1 / 3-1 / 2 of the lower wire rod 5, air-dry for 2-5 hours, pour the remaining height and scrape it, and air-dry for 24 hours;
[0019] Resin ropes are laid on the lower wire rod 5 to form the second resin rope layer 62, interlayer arc-shaped pr...
