A high grade precision machined shaft carries the rotor assembly which comprises the generator rotating field system,incorporating a fully interconnected damper winding, the exciter rotor/rotating rectifier system and cooling fan. The rotoris mechanically wedged and supported on the end winding to allow an overspeed of up to 2250 rev/min. On completionthe whole rotor assembly, is dynamically balanced to within precision limits to ensure vibration-free running. Thephotograph below shows the complete assembly.Typical 4 Pole RotorTherotorissupportedbyliberallyrated,sealedforlifeballbearings.,Depending on output and frame size the exciter can be mounted internally or externally to the N.D.E. bearing.The A.V.R. is mounted from the front panel (D.E.) of the terminal box.Removable access covers are provided at the D.E. and N.D.E. of the machine. Both side panels and top panel areremovable on the terminal box to provide easy access to the output terminals and other ancillary equipment.2
