Can you all find me a boat to put this motor in.

This is a motor that we are rewinding. It is a 270 hp, 2 pole, 3 phase 60 hz motor. It has 48 slots with 6 groups of 8 coils with a 1 and 16 span or the overlap. What this means is that one side of 16 coils must be layed in before the other side is layed in. The turns are odd at 4 and 5 turns with 33, 16 ga wires in hand. One group of coils weights 60 lbs each for a total of 360 lbs of copper wire in the motor.

Oh my gosh!

What does that motor turn and how fast?

I think it turns a pump. A 2 pole motor's base speed is 3600 rpms @ 60hz. With the slip in the rotor since it is a induction motor the speed is more like 3560 rpms at full load.

I have some 717 hp C15 cat diesels that drink 28-29 gal per hr @ loaded rpm. You know what that cost... ever 8 hrs 300 gallons Gone!! (re-fuel) Mark what does it take in cost to run that engine @ load per 8hr shift? care to guess? jw

I definatly could find you a boat that it could go into

However i would stuggle to find sufficent power source to run it..

The motor would pull a full load of 337.5 amps. This is about 266 kw and it would take about a 600 kw generator to get this motor running up to speed. I am guessing that 500 hp would be about right for a 600 kw generator. So I will guess about 20 gal per hour.

Mark,

How about bolt it to an 8x6x12f ITT AC Fire Pump? Should squirt out 1500 gpm at 175psi.....ish.

I always wanted to use a fire pump motor to propel a boat but the weight. Yikes.

I've never seen one but AC sells one that's 500 hp. It's got to be gigantic.

I work on a 1200 kw generator that drove 2 - 300hp cutters on a dredge. The pump for the discharge had a 6' dia impeller with a 3' discharge pipe. The diesel engine was manufacture by Electric Motor. They build low profile motors for tug boats, locomotives and use to build motors for submarines. But this engine had no oil pan, it used the bottom of the bilge for it's oil pan. The engine was a V16 cylinder and was almost 40' long. I saw a spare cylinder,piston and head and the cylinder was the size of a 35 gal drum.

Mark, that's awesome.

I designed a pump house with a pair of 3000 gpm diesel pumps on a 40000 gallon tank. At the 150% test mark we could drain the tank in just over 4 minutes. In fire protection terms that's a bunch O' water. Sounds like that dredge is a monster.
