Was stopped in Waverly VA today and low and behold a flatbed truck went by with a large AC electric motor on it, very unusual sight! Nice to see that old AC name tag on the side of it.

I think I saw one advertised somewhere in Tn. It said it was maybe a 1200hp electric I think.JP

I work at a nuclear power plant, we have an odd assortment of Allis motors up to three 2000 hp units for our condensate pumps. Very slow motors but hellacious torque and very reliable, we have the larger units rewound every 18 months due to continuous duty at high amperage(315-325a/4160v) loading. There are quite a few 50 to 200 hp 480v units we have that after overhaul come back with new Siemens-Allis decals.
