Default Enjoy this picture of a 4,500 HP electric motor

It was used to power a big blower at a coal fired electrical power
station. Then it was rebuilt, then the power station was shut down by
the EPA. The power station is 96 years old. They have a 96 years old
bridge crane that is still operational.

The blower at iFly is 1,600 HP, and this is 4,500 HP, almost 3 times bigger.

Couldn't find a good picture quickly, unfortunately...reactor primary
coolant pump motors are around 6,0000 HP (Oconee-class, 850 MWe output)
to approaching 10,000 HP for later 1100-1200 MWe units. There's enough
"waste" energy imparted from the impeller work that it's how initial
temperature is raised from ambient to 560 F at 2250 psia prior to
reactor startup. Oconee flow rate is 131.6E6 lbm/hr total or roughly
65,000 gpm thru each of the four RCPs...

Power plants do tend to be big machines...


I am taking pictures of their place, as I work there.

They have enormous vertical pumps also, impellers about 12 ft in
diameter. Powered by what clearly looks like antique giant
motors. Much bigger than the motor in the photo that I posted.
