Abstract

PURPOSE:To improve the electric characteristics of a coil against mechanical strength resistance by winding a lumped mica prepreg and a film prepreg as well as a flake mica prepreg and disposing the film prepreg at the closest side of a conductor. CONSTITUTION:An insulating layer 3 formed of a semicurable type insulating tape wound and solidified around a coil conductor 2 is composed by simultaneously winding a glass-backing lumped mica prepreg, glass-backing flake mica prepreg and polyimide film prepreg in such a manner that the polyimide film prepreg is disposed at the nearest side of the conductor. In this manner, the insulating breakdown strength characteristics of the coil against the bending strain can be improved.
