mostThree-phase asynchronous motorThere are winding burn and rewinding phenomenon, sometimes it will be found that the motor after winding rewinding maintenance, even if the wiring process, assembly process, etc., meet the requirements, but in normal operation and use of life will be greatly reduced. And the more the number of maintenance of the motor, the more obvious the shrinking of the life of the operation. todayMori machineXiaobian will take you to understand the "sequelae" after the overhaul.

       After the overhaulThree-phase asynchronous motorWhat causes this phenomenon? We do not consider the above wiring process, assembly process and some quality problems of enamelled copper wire, we should also take into account the impact of temperature factors.

       At present, the method of removing the burnt winding of the motor is generally three kinds of open fire heating, electric oven baking and high current heating which are not seen much. However, the vast majority of the staff of the three methods of the user are heated by experience, and not many are heated by the temperature controller. Because there are differences in the degree of experience, the heating temperature will far exceed the safe value that the stator core can withstand, generally180℃-210℃This range is about, which will cause the insulation between the stator core silicon steel sheet to be seriously damaged.

       Beyond this range, the stator core silicon steel sheet is like being "annealed" once, which will cause a significant reduction in the magnetic flux of the core silicon steel sheet! This will lead to a substantial increase in iron loss.

So we're targetingThree-phase asynchronous motorWhen winding is rewound, it is necessary to ensure that the wiring process and the whole machine assembly process meet the requirements, but also pay special attention to the winding removal, painting and other processes that need temperature heating treatment.
