Good news is that, there are machines special designed for recycling copper winding in the motor stator. Electric Motor Recycling Machine Electric motor recycling machine consists of two machines, copper wire cutting machine and copper wire pulling machine. The cutting machine cuts one end of the copper winding, while pulling machine pulls the winding out.
The recycling machine has high efficiency but only consumes quite small amount of power. It can dismantle motor stator with the diameter of 6cmcm. There are no damage to the silicon steel case. The copper winding are not bare, but are generally coated in enamel, which protect the wire from shorting itself out.
The copper content in a scrap motor varies according to the types of motor. Averagely, an AC motor contains percent of copper. If you are a motor recycler or manufacturer, you can start to consider buying motor stator recycling machine.
It will save your effort greatly while bring large profit to you. Copper wire cutting machine is used to cut one end of copper winding in the motor, while copper wire pulling machine is used to pull copper winding out of the motor.

Same here like to pile them up then get the grinder out gives me a sence of satisfaction and more money in my pocket as I don't have to pay off an expensive machine. Thanks 5, Thanked 5, Times in 2, Posts. When you have enough posts post a video of it working, Do the compressors need to be cut in half for it to work on them? Hand jobs are not that great!

Using a 9 inch grinder with cutting disc. You can up end it, grab the footplate and shake the compressor out, its hanging by a electric wire and a Steel metal tube, pop the wire off and cut the tube.
I then afterwards fill up the case with the Iron cores from transformers and motor laminations and tack weld two of them 'end for end' and get 'HMS in size' price for it. A bit of work and better when prices were higher. I do it anyway, not selling Steel for another 18 months I guess. Oh, main point here is that the Fridge Copper windings do not have plastic insulation around them, they are clean and lubricated by oil so they are easy to pull out.
I use one of these with a Cast Steel hook, and a hammer, to pick the loop end out after cutting the other ends loops off. I found it, so it was cheap and perfect for the job. I might mention that someone could make a jig to hold the motor core and use that tool in some way to pull the Copper loop out, like putting a small thrust bearing on the other ends screw and using a battery drill to tighten up the screw thread part, pulling the Copper out.
But I use use a vise and a hammer and ear muffs Last edited by eesakiwi; at AM. I would charge people per pound or per unit to use my machine. The fridge motors here I cut a bit different. Both the grinder and the wheels. After removing the top, most of them have 4 bolts to securing the electric motor to the compressor.
After removing the bolts, I cut the wire and it is done. I then use a razor blade to cut the threads securing the windings and pull the threads out.
After setting the motor aside for a while to allow the compressor oil to drain off, I cut one side of the windings with wire cutters, then pull them out from the other side with pliers or channel locks. It is a pretty easy process. The money is good for you and your family and recycling the motor is good for the environment.
You pull straight onto our certified scale. Then, you go directly to the steel yard where your truck is emptied, and return to weigh-in again and calculate the difference in weights. So, look around your home and business, grab all the recyclables you have and head over to our center. Stop throwing good money away! Valley Park, MO
