PURPOSE:To improve electric and heat dissipating characteristics by adhering powder resin which contains 30% or more of mica powder to an insulating layer wound with a glass tape except a filling port, and then fully impregnating synthetic resin through the port. CONSTITUTION:After insulated wires 1 of the prescribed number are aligned and formed in the prescribed shape, an insulating tape 2 is wound. Then, mica powder filling powder paint in which 30wt% or more of mica powder is mixed is coated except a filling port 4 of impregnating resin to form a mica powder filling powder coating layer 5. Then, synthetic resin is impregnated in vacuum. The impregnated synthetic resin is not externllay flowed out nor leaked since the layer 5 is formed as a tough containerlike coating, to harden the synthetic resin impregnated to an electric coil in the impregnated shape as it is. |
