A core support system is described by which the core structure and frame structure of a dynamoelectric machine can be manufactured independently in parallel operations and later assembled. The support system provides radially resilient support of the core structure while maintaining tangential stiffness by utilizing axially extending spring bars disposed in a cylindrical configuration about the inner periphery of the stator frame structure. The spring bars are rigidly attached to annular frame rings and can be radially deformed to be in firm contact with building bars of the core structure which can be axially slid into the frame during assembly.

A system supplying oil to the seal plates of a generator. Seal oil is provided by a primary pump and a secondary pump which acts as a backup for the primary pump. Under normal operating conditions a portion of the seal oil supplied by either pump is diverted through a bypass line so that only a predetermined amount of oil actually flows to the seal plates. When the flow rate through the bypass line falls below a specific amount, the secondary pump is activated. If, at any time, the oil pressure supplied to the seal plates falls below a predetermined amount, then a hydraulic accumulator maintains the necessary pressure and flow rate for a relatively short period of time required to bring the backup pump to its proper pressure and flow rate.
