World's Largest AC Motor
World's Largest AC Motor
(OP)
Does anyone know where the world's largest electrical Motor resides, what it is used for, and who makes it? I went to a Large AC Motor GE Seminar and found two motors that was used in a refinery for Motiva that drove Fans. The following was taken from an IEEE website "The ASU for the Motiva Delaware City repowering project depends upon the proper application and operation of very large synchronous motors, including a four-pole 66000-hp machine and a four-pole 43000-hp machine, the former being the largest 1800-r/min compressor driver ever designed and manufactured." ht tp://ieeex plore.ieee .org/xpl/f reeabs_all .jsp?arnum ber=952516
This article was written in 2001 so there has to be bigger motors since then.
Thanks in advance for any input. I tried search eng-tips for prior discussions and did not find any.

We actually have in our possession the old motors off the Seattle wind tunell. It was 36,000 hp wound rotor induction motor, 10 pole. It was coupled to a 20,000 hp synchronous motor thru an eddy-current coupling, and had a 450 hp wound rotor pony motor on the common shaft.
The 450 pony started the sync motor, which accellerated the 3600 thru the clutch. when the unit was up to slip speed, it was closed onto the power system to minimize impact on the utility.
I belive I read an article that both Siemens and ABB both have breached the 80,000 hp rating, but cannot find the artical.

One contender for 'largest' must be the motor-generators installed at the Dinorwig pumped storage hydro station in Wales. 330 MVA generating, 312 MVA motoring, 18kV, 500rpm.

A couple of million lb-ft, more or less.
RE: World's Largest AC Motor
500rpm @ 4,395,487,000 lb-ft, give-or-take.
Depends a little on what power factor the motor-generator is running at.

The two motors were part of a syn-gas plant that started when the place belonged to Texaco.
I nkow they had some process issues for quite a while and couldn't use the motors.

Must be "up there", in terms of torque

The hp's are low, often in the 50 to 200hp range but watch out for the flywheel. The stored energy in the flywheel does all the heavy work!

Look what I found. A gyratory crusher. Not as big as I 'imagined' and not using the airgap as a crushing chamber.
Check that:

135,000 hp, built by ABB, and continuous duty from 360-600 RPM. There were many reasons I kicked myself for forgetting my camera; this motor was one of them. BIG!

My work location has two generators that output 1350Mwe each. That would be equivalent to approx 1,350,000 horsepower each. Not slow speed, not motors, but still pretty dang big.
