Abstract

PURPOSE: To raise the efficiency of reduced pressure treatment by providing holes in wedge to fix coil housed in the groove of iron core and then by filling a ventilable material into the holes.
CONSTITUTION: The holes 7 are pvovided in the wedge 10 and the wedge base plate 9 to an extent that mechanical strength is not impaired. They are struck into the revolving armature core and their holes are filled with the ventilable material 8, e.g., felt, etc. In such a constitution, the air in the insulated wire ring 3 in the reduced treatment is degassed effectively through the felf 8, and also during the resin impregnation, resin is effectively impregnated with the aid of the capillarity of the felt as the ventilable material. Also, during resin during time, resin is effectively held by the surface tension of the felt 8, thus resulting in the stable combination of the wedge 10 and the wedge base plate 9 with the insulated wire ring 3 and assuring the fixation of the wedge.
