Novel main-generator rotor

The utility model relates to the technical field of generator rotors, particularly to a novel main-generator rotor. The rotor comprises coils, a support ring, a coil connecting line, an insulating spacer and a binding rope, wherein the support ring is arranged between the two coils; the insulating spacer is arranged between the support ring and the coil connecting line; and the support ring, the coil connecting line and the insulating spacer are fixed through the binding rope. The rotor has the advantages that the structure is simple, compact and reasonable, the assembly is convenient and fast, the connection is reliable, the amplitude at the weld portion of the connecting line is retarded, the connecting line is enabled to have the same amplitude with the rotor, therefore generated stress effects are reduced, rotor ground faults caused by coil insulation fracture can be prevented effectively, assembling problems caused by the altitude difference between the connecting line and the support ring are eliminated
