GER-4212 - GE Generator Rotor Design, Operational
2021-4-7 · centrifugal loading of the copper winding against the wedges and retaining rings is con-siderably reduced. Much larger diameters of the large four-pole generators permit use of deeper and wider slots to accommodate a larg-er cross-section of copper winding. Increased rotor diameter also increases the available pumping head for forced convection cooling.
