Abstract A dynamoelectric machine including stator and armature structures. The stator includes a yoke and a plurality of pole shoes carried thereby which include slots for receiving compensating coils. Strand-like elements are tightly packed within the slots between the compensating coils and the slot walls and are embedded within a hardened binder material, to support the coils against oscillation. Each pole shoe includes tip and base sections defining a pole face. The tip section comprises a plurality of lamination plates which have aligned apertures defining an opening extending through the tip section remote from the pole face. A connecting bar is disposed within this opening and has fastener elements mounted on each end thereof to clamp the lamination plates together. Threaded bolts are received in the connecting bar to draw the lamination plates toward the base section in uniform fashion. The yoke comprises a plurality of lamination plates which are arranged in mutually abutting relationship. A plurality of attachment flanges are welded across the outer edges of yoke plates to couple the plates together. The shoe base section is detachably secured to the yoke such that shoulder portions of the base section serve to clamp primary current windings in place against the yoke.
A method of assembling a pole shoe for a dynamoelectric machine, said shoe including a base section and a tip section; said shoe sections being relatively separable and defining open-ended slot means for the reception of compensating coil means; said method including the steps of: installing compensating coil means into said slot means; inserting a plurality of strand-like elements into said slot means so that said strand-like elements lie between said compensating coils and walls of said slot means then clamping said base and tip sections together such that said compensator coil windings are braced by said strand-like elements, then inserting a liquid binder material into said slot means, and allowing said binder material to cure so as to bond said strand-like elements together and to said wall means defining said slot means.
