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.
