Electric heating device used for removing motor stator copper wire

Abstract

The invention relates to an electric heating device used for removing a motor stator copper wire. The electric heating device comprises a workbench, an oblong hole, a positioning line, heating pipes, a connecting plate, nuts, a protective cover, a thermocouple, a U-phase lead wire, a V-phase lead wire, a W-phase lead wire and the like, wherein the positions of the heating pipes are adjusted according to the size of a heated stator, the twelve heating pipes are in circular distribution by reference to the circular positioning line on the workbench and are installed on the workbench by using the nuts to finally ensure an inner circle of the stator and a circle formed by the twelve heating pipes to be concentrically placed, and a thermocouple lead wire, the U-phase lead wire, the V-phase lead wire and the W-phase lead wire are respectively connected with a temperature control system and a three-phase power supply. When the stator is heated, a temperature value is fed back to the temperature control system by the thermocouple, the system controls the temperature to be constant for a period of time to melt insulating paint, and then the copper wire in the stator is taken out by using a tool so as to finally achieve the reuse of a stator core.

Description

Technical field [0001] The invention relates to an auxiliary device used when disassembling a motor stator copper wire, in particular to an electric heating device for disassembling a motor stator copper wire. Background technique [0002] We know that when the stator winding of the motor is damaged, if you want to reuse the stator core, you must first remove the copper wire in the stator. However, because the stator and the copper wire are soaked with hard insulating paint, it is necessary to smoothly It must be heated before disassembly. The traditional method is to burn the stator with copper wire on the fire, and then use a tool to remove the copper wire after the insulating paint melts. There are two hidden dangers in this way: one is that the local temperature is too high and it is easy to damage the stator punch. The material structure is severely oxidized and the magnetic permeability decreases, which greatly reduces the performance of the motor; the second is that t...

The traditional method is to burn the stator with copper wires on the fire, and then use tools to remove the copper wires after the insulating varnish melts. There are two hidden dangers in this way: one is that the local temperature is too high, and it is easy to damage the stator punching sheet The structure of the material is severely oxidized and the magnetic permeability decreases, thereby greatly reducing the performance of the motor; second, the stator slot is full of soot, which is difficult to clean and will affect the performance of the motor; The environment has polluted
