When repairing or dismantling motor, it is usually necessary to separate the stator winding enameled wire from the iron core. A motor winding enameled wire and iron core separation device with simple structure, low cost, wide range of motors and quick operation was designed. Firstly, the core of the winding to be separated was fixed in the clamping unit. Secondly, the enameled wire cutting unit was used to cut off one end of the winding enameled wire. Thirdly, the enameled wire clamp was used to clamp the enameled wire on the other end of the winding core. Lastly, the clamped enameled wire was removed from the iron core. The structure of the separation device was given, its working principle was analyzed, and the control system was designed. The test results show that the device makes the separation process safe, reliable, and does not damage the silicon steel sheet on one hand, and on the other hand, it makes the separating operation efficient, energy saving and environmental protection.
