    I used to do service work on those size motors and bigger, up to 500 hp. Did you use a crane truck to load it?

    That thing looks brand new. I hope you took it in because it was beyond repair.

    I got it from a buddy who is a owns a company that does field work on the motors. He loaded it with a forklift and 10 minutes later the yard unloaded it with a forklift. 2 more to do next week, hopefully

    Think I woulda torn that baby down just to see what it was made of. I'm not much for just going around cutting cords, but in this case, did you even do that? ; )

    I do not currently have the necessary equipment to maneuver these beasts yet. I did cut and keep all the copper and the conduit. I think this came off some sort of commercial refrigeration unit. I am not completely sure though. This morning we just loaded and only had to go 2 miles to the yard.

    What do you think the conduit is made of? It is a braided material and the magnet did not stick. Pretty hefty too

    I would have tried to open it up and check for copper ,then cut it out. would have been a nice payday. I do understand though as i also have no way to manuver something that heavy either.

    About 20 years ago I had the idea of re-manufacturing those large hermetically sealed roof top compressors, Carrier from Richmond B.C. was giving me all their warranty stuff. Once cutting them open the things I was finding wrong were minor.

    Getting a supplier who would would sell me valves and gaskets or the lack of one brought this project to a screeching halt. I did learn how gaskets were produced in mass and had a machine shop lined up to make the reed valves but cost exceeded common sense.

    I still have it in the back of my mind to learn about rewinding motors, I thin that there is a good future in it or in my case something to pass the time. While kicking pebbles around the Electric shop parking lot this morning had a chance to speak with the owner and he is willing to put one of my re-winds to the test of time.

    We so often do not recognize opportunity when she comes knocking at our door.

    A three phase motor is so much easier to rewind even by hand of a single phase motor as there are no start windings to wind, the 3 coils inside a the 3 phase make a star if you have th wrong rotation changing any two hot leads changes this while single phase motors are so much more complicated.

    Our transfer pump used to pump the gray water in the septic tank to the field over at the house we have for sale burned out the motor is nothing special, to replace that pump it's going to cost over $800.00. Given the fact that a 1/2 hp motor would have less than 3 lbs of copper wire, if said copper was $20.00 a lbs on the roll it would cost me less than $60.00 to repair the motor.

    If anyone is interested i will dig out the tittle of a very good book I have on re-winding and trouble shooting electric motors.

    That motor would have run a hydraulic pump and its brand new. What a shame.

    It wasn't mine to sell. I was told if I wanted to scrap it I could but couldn't do anything else.

    The book I have on Electric Motor Repair which is also the tittle, covers the winding, repair and troubleshooting of AC and DC motors and controllers. Written by Robert Rosenbeg who also taught the trade at the George Westinghouse Vocational School in New York City.

    The book does not have a library of congress number ( ISBN ) so if your going in search of the book the author and tittle will have to suffice.

    834x.23=191.82. I have stripped a few(a lot)motors and if this particular would yield 10% of copper thats 83# x2.70=224.That leaves 751# x.10=75. 224+75=299. I have sold the rotors for alum.breakage ranging from.18 to.28 so that would have added up as well.Not preaching or anything but there is profit to be made.I would have stripped this in the back of the truck or trailer also like someone mentioned above.I love those motors

    Hey guys he did say he's getting two more next week. Hopefully you can break down the next one BandB. Like the name, mix it with some cola and watch the sunset.

    If it is cast you could crack the case ,it is kinda round so you could roll it but Even dismantled it might only boost price by $100 or so & you will work for that money
