The strength of this framemaintains a uniform air gap underall operational stresses. Stator laminations are precision-punched from high-quality low-losselectrical sheet steel which are coatedwith a thermally stable insulation film(C5 coating) to minimize eddy currentlosses. The laminations are assem-bled in accurate alignment within thestator frame to form the stator ducts are formed fromsturdy I beams spaced for strengthand noise control.

5 The core is clampedunder heavy uniform pressure in theframe to prevent distortion. The result-ingassembled stator structure hassuperior strength and rigidity, whichwill promote quiet performance, longlife and trouble-free FrameStatorGE Motors can manufacture bracketbearing machines up to 67,000 HP(50,000 kW) and offers pedestalbearing machines throughout ourproduct range. The bracket frame is similar in con-struction to the Pedestal machines,except that the frame extends pastthe end of the winding in order tomount heavy gauge fabricatedsteel endshields and the type of machine has the corepiled outside of the frame. The coreis wound and then mounted intothe support of the stator coil ends iscritical to the ability of the machineto withstand the mechanical forcescaused by starting, external shortcircuits and impact loading.

The insulation system issubjected to rigorous testing accord-ing to applicable IEEE, IEC, NEMAand API standards. All but the very largest wound statorsundergo global vacuum-pressureimpregnation (VPI) treatment.

After curing, it bindsthe stator components into a solidand rigid structure with excellentdielectric strength, dimensionalstability, and mechanical also increases the resistance of thewinding to thermal shock, moistureand other contaminants.
