Description
Technical Field
The invention relates to the field of motors, in particular to a device for removing a motor stator winding without damage and a stator winding removing method.
Background
At present, the winding burning and rewinding operation experience of an over-motor (most of the motor is a three-phase asynchronous motor) can be observed, and the normal operation service life of the motor after winding rewinding maintenance is greatly shortened compared with the original normal operation service life even if the wire inserting process and the assembling process meet the requirements. Moreover, the more the motor is subjected to maintenance, the more the service life of the motor is shortened, and the more the motor is obviously. The reason for this is that, in the present case, the method of removing the burnt windings of the motor is not unusual: open fire heating, electric furnace baking and less frequent heavy current heating. However, most operators heat the water by experience when using the three methods, and the temperature of the water is rarely controlled by a professional temperature controller. Therefore, the difference caused by different degrees of experience often causes the heating temperature to exceed the maximum safe value that the stator core can bear (the value of the ordinary motor is about 180-! Furthermore, after a hot baking process at high temperature, the silicon steel sheets of the stator core are "annealed" one time, resulting in a significant reduction of the magnetic flux of the silicon steel sheets of the core! The net result is a large increase in iron loss for the motor undergoing such maintenance! This is also exactly the root cause of the above fault! Therefore, when the motor winding is rewound and maintained, the procedures such as winding detachment and paint dipping which are seemingly irrelevant and require temperature heating treatment are paid attention to while the wire embedding process and the whole machine assembly process on the surface are ensured to meet the requirements, otherwise the remaining sequelae are not ignored!
Moreover, most of the existing stator winding disassembling methods are that after one end of the stator winding is completely cut off by a cutting tool (such as a manual steel bar shear), the other end of the stator winding is directly pulled out by a wire cutter in a manual mode or a stator winding pulling tool. The inventor finds that such direct pulling out of the stator winding is likely to damage the inner wall of the stator slot and also reduces the service life of the motor after maintenance.
