Abstract
A ripple spring is provided having one or more conductive layers, and one or more non-conductive layers. The conductive layers and the non-conductive layers are laminated together to form a symmetrical stack of layers. A method is also provided for monitoring the ripple spring. The method includes the steps of providing a ripple spring that holds a winding in place, where the ripple spring is positioned at least partially within a stator slot defined within an electromechanical device. Providing a conductive layer disposed within the ripple spring, and generating signals from the conductive layer, the signals corresponding to at least one aspect of the ripple spring. An analyzing step analyzes the signals to determine the at least one aspect of the ripple spring, wherein the at least one aspect facilitates an identification of faults in the ripple spring.
