A stator core for a dynamoelectric machine includes two pairs of dovetail slots disposed at respective predetermined radial positions in each armature slot. All stator slots contain armature bars. A few equally spaced stator slots also contain 'P' bars atop or radially inward from armature bars. Wedges are installed in the radially outer dovetail slots of stator slots containing only armature bars. Wedges are installed in radially inner dovetail slots in stator slots containing both armature bars and 'P' bars.

An improved support system for 'P' bars is disclosed, wherein the 'P' bar is mounted in a stator slot of the stator core of a dynamoelectric machine which has an integral excitation system. The support system includes a number of elements, all of which, in combination, serve to secure the 'P' bars in the slots of the stator core and, additionally, provide a low friction interface between the 'P' bar and the support system such that the 'P' bar is independently suspended and is actually capable of slight movement along its longitudinal axis.
