world's bigest motor posibly

saw the shredder this would drive today on modern marvels. biggest motor I've ever heard of. I didn't think electric motors could even get over 500HP. this one is 8000 HP.

I guess this is for the power hungry.

I found out the largest electric motor built has a rating of 55 MW, but it didn't state how much horsepower it delivers.

 

I've never seen them myself, but my boss was reminiscing lately about a place who builds motors so big that they have to be built on site. The stator/case is cast in concrete and is the size of a jetliner. Tens of thousands of HP and running on high voltage.

 

Biggest motor I ever saw powers this wind tunnel test facility.

I did a lot of work out ther in the 80's and 90's and got to get a look at this monster. There is a small placard next to it with some info about it. I don't remember the exact numbers, but it's something like this: It's taller than a 2 story house ( tunnel itself is a little shorter), and it's about 75-100 feet long.

The rotor is constantly turning at a very low speed, they claim if it stops, it could bend from the great weight. To keep it turning there is a smaller motor that rotates the big motor via ring gear. I did not see the smaller motor. They have to coordinate with TVA when they plan on running it.

A little more, 2 of the motors are 83,000 hp EACH..http://www.nimr.org/systems/images/pwt.html

 

These ones are pretty big:

I asked my boss again today about those motors he saw. He said they were built by Westinghouse. Here's their brochure for their larger motors, up to 31,000HP. They make bigger ones apparently, like the ones that he saw being installed, but I guess those are special order. He said he saw them laying giant field coils into a poured concrete stator.

 

Not an electric motor...but....
I was at the Smithsonian once in Washington, Dc ...taking a break cause there is so much to see...
I was in the Science and Industry Bldg (I think) and I was leaning on a metal column....I noticed that the column went down through the floor thru a metal grate ...as I looked down to the floor below..I saw the wrist pin on a huge piston....I was leaning on the piston shaft and above me about 10 ft. was the head of the piston...
I was a piston out of a subway engine from the 1930's or something...
I guess it was all cast iron....amazing...
