Abstract

PURPOSE:To prevent corona discharge by providing slot liners with elastic and transformable projections and the slot liners are wound around windings wherein varnish is immersed after incorporating into a slot and the liners and a slot wall are securely and uniformly contacted. CONSTITUTION:Slot liners 7 lying betwen coils and a slot wall of core are provided with plural round type projections 7A by projecting at nearly fixed pitch. The slot liners 7 are wound around the insulating layers 2 of self-coils and inserted in a slot so that the inner fringe sections 7B of the projections 7A may elastically combine with the side wall of the slot. Varnish is then immersed under vacuum. In this way, the slot liners 7 are securely and uniformly contactes with a slot-side wall and local field concentration will not be developed and it is possible to prevent the occurrence of corona discharge.
