Abstract: Disclosed is a system for measuring stator wedge tightness in a stator core of an electric machine. The system includes at least one sensor located along at least one component disposed in a stator slot of the stator core. The at least one sensor is located and configured to measure strain in the component. The system further includes a data acquisition system operably coupled to the at least one sensor. A method for measuring stator wedge tightness in a stator core of an electric machine includes arranging at least one sensor along at least one component of the stator core, the at least one sensor being located and configured to measure strain in the component, and interrogating the at least one sensor utilizing a data acquisition system.

Abstract: A system and method to measure a characteristic of a component of an electric machine. The system includes an optical fiber disposed proximate to the component, at least one sensor, disposed along the optical fiber, to detect the temperature of the component, and a data acquisition system operably coupled to the sensor via the optical fiber to generate real-time data in accordance with the detected temperature of the component during an operation of the electric machines.
