PURPOSE:To eliminate generation of gaps in a coil, when manufacturing the coil in such a manner as to coat resin on an insulated conductor while winding it, by providing further coating of powdery insulating material on the portions of the conductor where gaps between the conductors are liable to get larger. CONSTITUTION:After an insulated conductor 1 is passed through a resin coating device 2 to be provided with coating of necessary amount of resin 3, it is wound into a coil core 7. At that time, the portions of the insulated conductor, where gaps between the insulated conductors are liable to get large, like the portions of transposition, are provided with further coating of powdery insulating material 6 after having passed through the resin coating device, and finally, the coil as a whole is treated for hardening. It is possible, by doing so, to eliminate generation gaps in the coil, prevent sliding or disarray between the conductors and improve the thermal conductivity. |
