Abstract
PURPOSE:To raise dielectric breakdown strength in simple structure by making the end of a slot insulating material project with enough length from the end face of an iron core and inserting an inverted U-shaped insulation material and a wedge from the opening of the slot and impregnating it with resin. CONSTITUTION:The end section 8 of a slot insulating material 7 that is placed at the bottom of the slot 2 is made to project with enough length from the end face of an iron core 1. A winding 4 is placed inside of this slot, and after the upper part of the slot insulating material 7 is overlapped on the winding 4 so as to enclose it, an insulator 9 under an inverted U-shaped wedge is inserted with length over a half of the depth of the slot from the opening of the slot, and, further, a wedge 10 is struck on the insulator 9 and it is impregnated with thermally hardening resin and the resin is hardened.
