| 1. A rotor of a rotating electric machine comprising:
a rotor main shaft of the rotating electric machine;
a pair of center hole copper bands arranged in a shaft center portion of the rotor main shaft and held in an insulated state
from each other;
a collector shaft fastened to a shaft end of the rotor main shaft and mounted with a pair of collector rings which supply
a field current, on an outer circumferential surface thereof;
a plurality of longitudinal lead bars inserted in and electrically insulated from lead grooves which are provided in an outer
circumferential surface of the collector shaft to extend along a longitudinal direction of the collector shaft, and connected
to the collector rings through conductive studs;
a plurality of radial lead bars arranged at a shaft end portion of the rotor main shaft, the shaft end portion being located
on a coupling side with the collector shaft, and including inner end portions connected to the center hole copper bands; and
a plurality of conductive longitudinal studs inserted into a plurality of longitudinal through holes provided at a shaft end
portion of the collector shaft to extend along a longitudinal direction of the collector shaft, the shaft end portion being
located on a coupling side with the rotor main shaft, and including one end portions connected to outer end portions of the
radial lead bars and the other end portions connected to the longitudinal lead bars.
