ABSTRACT:
A support system for an electric generator having a spring bar connected between the stator frame and a vertical spring plate mounted on a foundation. The spring bar provides flexibility in the tangential direction to minimize the magnitude of torque loads transmitted to the foundation during short circuit operating conditions. The spring plate provides flexibility in the radial direction to minimize the magnitude of vibration loads transmitted to the foundation during normal operating conditions. The combination of a spring bar with a spring plate allows the support system designer to optimize the natural frequency of the support system in both the tangential and radial directions.
