Scrap value of large electric motors, vs. small motors
I have several electric motor-like things, they are called
motor-generators. It is a motor paired to a generator. For scrap purposes, they are both electric motors. They are about 100 HP in size. I bought them as complete units and I expect that I will be scrapping them and selling off contactors and such. When I look up prices of "scrap electric motors", I only see prices published for fractional horsepower motors. My question is, are large motors valued at a higher price per lb, or lower, than fractional motors. The total weight of these devices is 14,000 lbs, so I better do a good research before selecting a particular scrap yard. i |

Before you scrap these beauties - consider they
might be worth something to you. I use a rotary to generate 3 phase. Simple 220 AC on the motor side and take 3-pase off the generator side. What are the names on them - any specs ? 100 HP is very large and 14K pounds is a few pallets!

As a whole unit, or separate the copper & steel. An air chisel will cut the windings so they can be removed. |

For scrap purposes, they are both electric motors. They are about 100 HP in size. Since they are made by Kato, I doubt there is any way to separate the motor part from the generator part. If that is possible, you might be able to sell the motor part and scrap the generator part. Many years ago I toured a plant that used similar motor generators to power Florescent lighting. They claimed that by using a higher frequency the lamps were more efficient. But I think those days are gone as the electronic ballasts essentially do just that. But you might check with one or more of the folks that make ballasts for florescent lighting. As for the price of large motors for scrap. Call three scrap yards and see what they will pay. Dan |

While I will soon know for sure, this is indeed what I expect, that they are closely coupled. I am just thinking out loud, but, even if they are closely coupled, the motor part probably has a SAE bolt pattern, so that it can be used where other similar SAE motors are used, say to replace a diesel engine or some such. i A very long time ago I had a very little to do with a Kato motor generator. It was DC to AC. As I remember the motor and generator were all on one shaft. This was for a weight critical application so maybe the big ones are a lot different. Dan |

The purpose was several-fold. First, hf is easier to filter to DC in each of the many, many boxes used to make up the "computer". I saw a 360-195 in a NASA building in Maryland that was about a city block in size. Computer took up the ground floor. The second purpose was to be a UPS, before such things were available. The flywheel action of all that weight spinning at high speed would be able to continue to supply power when the commercial power dropped a cycle or more. Third, the voltage was constant in spite of commercial power voltage fluctuations. My vote is disassemble one to determine the copper value. Paul |

I'm so old I'm of the day when we were still using the Philco 2000 w/ the 27 7-track tapes...and it was a (relatively) low-power as was first transistorized machine introduced in the class... Never had much occasion on IBM--after Philco were CDC or Cray shops primarily altho ORNL did have an IBM by time moved to Oak Ridge I had shifted my focus to embedded systems in a shift from one end of the computing genre to nearly the other extreme...did a couple of small tasks for X-10 on the IBM/DEC-20 combo but not enough to do more than say ran a couple of jobs on them...SAIC had gone VAX and were trying to do everything in house on it to pay the bill instead of using client machine if at all possible when did have needs. But, for about that period from the CDC before the PC was capable enough to do useful simulation, etc., I was almost totally involved w/ robotics for REMOTEC or monitoring/control systems for the utilities replacing/augmenting the original nuclear station analog control systems once NRC finally lifted the ban on their use in safety/control systems. -- |
Scrap value of large electric motors, vs. small motors

If this has 400 Hz output, the aviation folks might be interested, although 100 Hp is probably more than they need. There are places that run really heavy 400-Hz loads, however, such as where NASA runs air force radar dishes for tracking radars and telemetry. Just a thought, Jon NASA would not buy from me, that's the problem. Based on my most brutally honest evaluation, these units, while almost new, have no resale potential. They do, however, have relatively large potential to be parted out and scrapped. Almost new size 3 contactors, breakers, copper, motors etc. i Cut the windings out and sell the copper separately from the frames. You will get more for the copper alone tnan for the entire M-G sets - and still have the steel left. Cases are likely maleable iron - which has different value than steel - and is worth more separated than mixed. |

For scrap purposes, they are both electric motors. They are about 100 HP in size. I bought them as complete units and I expect that I will be scrapping them and selling off contactors and such. When I look up prices of "scrap electric motors", I only see prices published for fractional horsepower motors. My question is, are large motors valued at a higher price per lb, or lower, than fractional motors. The total weight of these devices is 14,000 lbs, so I better do a good research before selecting a particular scrap yard. That depends on how you scrap them. As a whole unit, or separate the copper & steel. An air chisel will cut the windings so they can be removed. I was planning to scrap the motors (stripped of electrical controls and enclosures) as a whole. Not much. Strip them and make about $50 an hour |
