Description

Technical Field

[0001] The utility model relates to special equipment for dismantling enameled wire windings on the stator core of waste motors, belonging to the technical field of waste dismantling and recycling. Background Art

[0002] When recycling old motors, the motors need to be fully disassembled to achieve the classification and reuse of different waste materials and different metal types. In particular, the enameled wire windings wound on the stator core are generally copper wires, which need to be disassembled individually to recycle the copper.

[0003] There are already many similar devices in the prior art, such as a waste three-phase motor stator copper wire dismantling device with Chinese patent publication number CN111564937A, a copper wire dismantling device for motor stator with Chinese patent publication number CN116961327A, a clamping and decomposition tooling for motor dismantling and copper removal with Chinese patent publication number CN110756560A, a waste motor dismantling and recycling integrated machine and recycling method with Chinese patent publication number CN103978019A, and a waste motor dismantling and recycling line with Chinese patent publication number CN213530150U.
