Technical solutions for the cause of motor burnout

According to the brief summary of the reasons why the motor was burned, some technical measures to prevent the motor from being burned are proposed below.

1. In order to prevent the motor from being burned due to poor sealing of the motor, the following measure should be taken:

(1) When overhauling the motor, the seal of each part of the motor should be checked, and no details or small parts should be missed;

(2) In addition, when this situation occrrs, the maintenance cycle of the motor should be shortedned, so that the problem can be found in time, the prime minister can be solved as soon as possible, and the loss can be minimized.

2. In ordet to prevent the motor from being burned due to damage to the bearing of the motor or bending of the bearing, the following mwasures should be taken:

(1) When unloading or reinstalling the bearing of the motor, it is usually necessrty to use the bearing heater to simply heat the bearing to 80 degrees Celsius to 100 degrees Celsius to ensure the quality of the bearing;

(2) Carry out a comprehensive inspection when reinstalling the bearing to ensure the normal use of the bearing;

(3) The bearing must be carefully cleaned before installation, and no impurities should be left in the bearing cavity, and the bearing must be cleaned before installation.

3. In order to prevent partial burning of the leveling due to the long end of the motor winding or partial damage of the winding and the friction with the end cover or other accessories, the following treatment should be done:

(1) When overhauling the motor, no matter what rigid objects are determined not to touch the winding;

(2)When updating the winding of the motor, itis strictly required to insert the wire according to the original data;

(3) When using an oper flame, be sure to keep a certain distance between the winding and the open flame;

(4)When reinstalling the motor, it is necessary to carefully check the winding to confirm the intergrity of the winding so that the motor can work normally.

4. In order to prevent the motor from being burned due to long-term overload or overheating, the following measures should be taken:

(1) Overload work will cause great damage to the motor, so rty to avoid overloading the motor and strengthen the protection of the motor;

(2) Keep the motor clean at all times so that the heat dissipation performance of the motor is good;

(3)Frequent starting of the motorhas a great impact on the life of the motor, so try to avoid frequent starting of the motor,so that the motor can be used normally and in good condition for a long time.

5. When the motor is burnt due to incomplete protection of the motor, it should be noted that:

(1) First of all, during the normal operation of the timing, the operator should pay attention to the load current all the time, and test the load current from time to time to ensure that the ratiio balance value of the load current does not exceed 10%, and minimize the load current The influence of the motor will eventually lead to the probability that the motor may be burned.

(2) Relevant personnel should regularly check the temperature, sound, vibration and other factors of the electrodes;

(3)Maintenance personnel must regularly monitor the sound of the bearing. The general lofe of the grease rolling bearing is 5000h, and the grease needs to be changed after about 1500h of work;

6. Maintain the starting device

The starting devive of the motor plays an important role in the motor. Its quality directly determines whether the motor can operate normally. Therefore, maintaining the starting device of the motor is a prerequisite for protecting the motor. It is precisely because the starting device of the motor does not work normally that it is easy to cause the motor to be burned. Therefore,it is necessary to maintain the starting device of the motor, and it is particularly important to maintain every step in the preparation for the starting wokr. For example, when starting the motor Before starting, check whether the contact points of the motor contactor and the wiring screws are normal and reliable, wheter the mechanical parts of the motor are also normal and reliable, and whether the brand is in a relatively good working condition. After these preparations are completed, the complete inspection is qualified, before the motor can be started, thus ensuring the normal operation of the motor without causing the motor to be burned.

7. Properly improve the working environment of the motor

The working efficiency of the motor is very high, but it is directly related to various exernal factors that affect the efficiency ot the motor. Therefore, the working environment of the motor must be clean, clean and dry in general.

(1) First of all, having good ventilation conditions is the prerequistite for the normal operation of the motor. Under good ventilation conditions, the normal heat dissipation of the motor can be guqranteed, and the motor will not be burned out due to the high temperature of the motor.

(2) Secondly,it is necessary to ensure that the working palce of the motor is strictly required by the normal operation of the motor, that is, to prevent various external factors from affecting the work of the motor, for example, to take moisture-proof and dust-proof measures for the working environment, Anti-corrosion measures to the motor,etc., so as to ensure the integrity of the timing.
