  • Method of retaining a winding element in a stator slot
    Patent number: 5822845
    Abstract: Stator bars and stator coils (winding elements) for a large dynamoelectric machine which are to be permanently placed in the slots of the magnetic core of the machine are wrapped so as to be surrounded on three sides with an elongated sheet of an elastomeric substance. A stretching device is attached to the two overlapping edges of the elastomeric sheet in such a manner as to be able to stretch the sheet around the winding element and thus reduce the thickness of the elastomer. The winding element surrounded by the stretched layer of the elastomeric substance is placed in a selected stator slot and the stretching device is detached from the elastomeric material. The elastomeric material attempts to regain its former thickness but is confined to the remaining space between the winding element and the sides of the slot. The offal is trimmed from the elastomeric substance and the winding element remains lodged in the slot.
