Electric generator, foundation pedestal for electric generator, and maintenance method for electric generator

A maintenance method for an electric generator applied to a power plant in which both axial ends of the electric generator are connected to respective rotary machines, the maintenance method comprising:

• providing the electric generator with leg plates for placing the electric generator on a floor face of a foundation pedestal, forming a bottom portion of the electric generator to have a bottom plane capable of supporting a weight of the electric generator, and forming a gap between the bottom plane of the electric generator and an opposing floor face of the foundation pedestal such that a carrier device capable of lifting up and horizontally moving the electric generator can be inserted into the gap while the electric generator is placed on the floor face of the foundation pedestal via the leg plates;
• and
• providing the carrier device in the gap, and lifting up and horizontally moving the electric generator by the carrier device, and thereafter doing maintenance of the electric generator.
