ABSTRACT:
An improved end winding support system for "P" bars is disclosed wherein each "P" bar extends axially from one end of a stator slot of the stator core of a dynamoelectric machine which has an integral excitation system. The support system includes means for affixing each of the "P" bars to stator bars at three different locations in the end winding region and especially in such a manner that the inner section close to the stator core includes a slip plane capable of accommodating relatively small differential thermal expansion displacements in the axial direction between the "P" bar and the stator bars.
