Truck and motor of a 363 "Brigitte" electric loco. The commutator of a 363 motor being skimmed by a computer controlled lathe
That traction motor certainly looks big! Much larger it seems than what I can mentally picture of those over here.
Yes those motors certainly are big! Actually two motors on one shaft, the two commutators and windings can be seen on the one being machined. These are French built locomotives, they were keen on "monomotor" trucks at that period. It is usual to have one motor per axle on new locomotives. IIRC the gears can be switched between passenger and freight usage. To give either higher speed or higher tractive effort at lower speed.
These locomotives are rather the same than X996, the locomotive that had been tested by Amtrak nearly 40 years ago that was a lend from french national railroad, adapted from 6500/21000 Class... Now all these are withdrawn from service. Dom
