A quick disconnecting device for enameled wire of electric motor

Abstract

The invention relates to a wire removal device, in particular to a quick wire removal device for enameled wires of motors, and belongs to the technical field of electromechanical maintenance. The stitch removal device includes a fixing part and a pulling part, and the fixing part includes a base and hooks arranged on the base. The stitch removal device provided by the present invention can realize fully mechanized operations, save labor and time, and reduce the working intensity of workers. , and the uniform disassembly force prevents the disassembled motor from secondary damage.

Description

technical field

[0001] The invention relates to a wire removal device, in particular to a quick wire removal device for enameled wires of motors, and belongs to the technical field of electromechanical maintenance. Background technique

[0002] When the motor is in use, the stator coil is often burned due to various reasons. In order to reduce costs, the burnt enameled wire is usually removed, and the motor is reused after rewinding the coil; however, the impregnated insulating varnish is cured The last enameled wire is quite difficult to remove. The tools currently used for removal are crowbars and wire cutters. According to the applicant's statistics, it takes 6 hours for a worker to remove the enameled wire of a motor less than 37kW, and 6 to 16 hours for a motor above 37kW. Hours, from these data, we can see that the demolition process takes a lot of time. Using manual tools such as crowbars and wire cutters for a long time, the labor intensity of workers is very high, a...
