Abstract
An electromagnetic apparatus in which a semiconductive liner of which at least one side is processed by mold releasing material is provided between the winding embedded in the slots of an iron core and the wall of the slot, and the remainder of the slots is filled with adhesive. The liner employed prevents the winding from adhering to the wall of the slot with the result that the insulating layer of winding is not damaged during thermal cycling and also corona discharge is prevented.
