ABSTRACT:
A constrained ripple spring assembly 26 is disposed in the radial slots 12 of a dynamoelectric machine and radially between the windings 14 and the wedges 20 maintaining the windings in the slots. The ripple springs 28 are adhesively secured to flat surfaces, for example, the underside of the wedges or one or two filler strips 30, 32, such that the spring assemblies are substantially flat upon insertion. At a predetermined elevated temperature, the adhesive bond is broken, enabling the spring to expand into a natural corrugated shape to apply a radial loading against the wedges and winding.
