ABSTRACT:
An apparatus and method for suspending a stator core (100) in an electric generator upon a foundation (206), where two natural modes of vibration, including known second and third modes, are excited in the core, each mode having four loops and four nodes displaced 45 degrees between the second and third modes. A non-rigid connection (212) connects a yoke to the foundation, and two connection members connect the yoke to the stator core at opposite sides of the non-rigid connection. The two connection points (210a,b) are located at adjacent loops of one of the second and third vibration modes. By this arrangement, radial deflections of the stator core at the respective connection points are transferred into a rocking movement of the yoke around the non-rigid connection. Thereby, vibrations transferred to the foundation are considerably reduced during operation.
