We have compiled some answers on how to extract copper from motor rotors and are sharing them with you, hoping they will be helpful.
1. Motor Rotor Copper Extraction Machine
The used motor rotor copper extraction machine is currently the most advanced used motor rotor dismantling equipment in China. In the past, manually dismantling small motor rotors was time-consuming, labor-intensive, and costly, or could only be separated by incineration. These rotors could not be directly processed and were even discarded, resulting in waste of metal resources and environmental pollution. The emergence of the used motor rotor copper extraction machine makes it possible to directly crush and separate difficult-to-process used motor rotors without sorting. Rotors of large, medium, and small motors can all be crushed, effectively solving the problem of difficult motor rotor dismantling and realizing the automation and mechanization of motor rotor processing.

2. How to Remove the Copper Core from an Electric Hair Clipper Motor? First, use a flat chisel to cut open the copper cladding along one end of the motor core. Then, invert the motor and heat it with firewood until it is almost completely burned. Use an iron rod to pull it out from the other end, and it can be easily removed! The method for removing the copper wires inside the motor is as follows: If the motor does not require repair, simply cut off one end of the copper coil with a sharp tool.
3. After cutting, place the motor over a fire to burn off the internal insulation and protective material. Then, use other tools to pull out the copper coil directly! If the motor needs repair and reuse, carefully chisel off one end of the copper coil.
4. Then, place firewood inside the motor stator cavity to heat the motor.
5. After the motor is heated, use a tool to wind the copper wires inside the motor and carefully pull them out! Pull the wires slowly and do not use excessive force.
6. Be careful not to damage the silicon steel sheets inside the motor stator cavity! Remember: If repair is indeed necessary, after removing the copper coils, be sure to carefully check the number of turns, wire diameter, length, and span of each coil! The data must be accurate and reliable!
The copper wires inside the motor stator are cut and pulled out using a stator copper wire remover. Under the action of a hydraulic cylinder, the copper wires are completely removed. This equipment is a new type of environmentally friendly device, mainly used for disassembling and reassembling old motors. The internal copper wires are completely removed, and the disassembly process poses no threat to the surrounding environment or personal safety. Furthermore, the removed copper wires are very intact, greatly increasing the recycling rate, thus enabling the equipment to be widely used in this industry.
