Claims

[Scope of utility model registration request]

(1) In a field coil formed by inserting an interlayer insulator between the layers, winding the coil conductor flatly a predetermined number of times, applying tape insulation to the outer periphery of the straight portion, and vacuum-impregnating the coil conductor with an insulating resin, the coil conductor has a straight line. It is applied to the top and bottom of the section, has an introduction path communicating with the inner section from the outside, and is equipped with a pair of upper and lower insulating plates wrapped around the tape insulation of the straight section. . A flat-wound field coil, characterized in that the vacuum-impregnated insulating resin is guided inward through the introduction path and infiltrated between the layers of the coil conductor.

(2) The flat-wound field coil according to claim 1, wherein the introduction path of the insulating contact plate is formed by a vertically inclined groove extending through the inner surface in the axial direction.

(3) The introduction path of the insulating plate is formed by a plurality of through holes provided from the outer surface to the inner surface, and the tape insulation is provided with communication holes that communicate with these through holes. A flat-wound field coil according to claim 1 of the patented utility model.
