Claim 10:
11. A method for repairing a loss of support of a rim of a rotor during operation of an electrical generator, the rotor of the electrical generator being disposed for rotation about a vertical axis, the rotor comprising a shaft extending along the vertical axis, a spider attached to the shaft and extending radially away from the shaft, the spider having vertically spaced apart top and bottom sides with respect to the direction of gravity, the rim carrying poles and surrounding the spider, the weight of the rim normally being totally or partially supported on ledges disposed on the spider during normal operation of the electric generator, the loss of support of the rim being caused by mechanical failure or loss of at least a portion of the ledges, the method comprising:
fastening at least one support member on a top side of the rim adjacent the top side of the spider, each of the at least one support member extending away from the rim and over the top side of the spider,
wherein the at least one support member transfers at least a portion of the weight of the rim to the spider to support at least a portion of the rim against the top side of the spider and thereby relieve some or all of the weight of the rim being supported by the ledges without the need to repair any of the failed or lost portions of the ledges,
wherein the rim is lifted off the ledges after fastening the at least one support member on the top side of the rim adjacent the top side of the spider.
