ABSTRACT:
In an electrodynamic apparatus, a method of securing a coil basket of the type that includes a plurality of top coils and a plurality of bottom coils to a bracing assembly that includes a plurality of support braces includes steps of banding the top coil, the bottom coil and the support brace to each other; positioning a number of inflatable bladders, respectively, between the top coils and the bottom coils in the location of the bandings; and simultaneously inflating the bladders to a predetermined pressure that is sufficient to tension the bandings to a predetermined force, whereby forces that are transmitted to the coil basket from such inflation are imparted evenly throughout the coil basket and at the same time. An improved end winding region support system is also described.
