Common faults and maintenance methods of high-speed motors
2022-9-7
high speed motorIt is a high-end motor product with high-speed operation. Its performance is stable during use, so the probability of failure is very small. However, high-quality high-speed motors will also have various failures due to long-term use or improper maintenance by users. Therefore, in order for users to identify various faults in a more timely manner, let's analyze the common faults of the motor and the corresponding maintenance methods.
First: The main drive motor is not running normally
During the operation of the high-speed motor, it is often encountered that the main drive motor is not running normally. When such a fault occurs, it will cause the motor to generate severe vibration, and cause the bearing to heat up and cause serious wear. The operator checks whether the motor bearing is missing. Lubricating oil and ensure the normal operation of the high-speed motor by adding lubricating oil.
Second: motor shutdown
The occurrence of this kind of fault generally needs to observe the change of the ammeter pointer in the electric cabinet of the speed regulating motor, and check whether the thermal relay overload protection used by the high-speed motor is working normally. When this fault occurs, the operator can clean the terminal or wire Tighten the terminal screws to see if the high-speed motor can run normally.
Third: Motor heating
When the high-speed motor heats up, the main reason is that the current is too large. The long-term continuous heating will cause the temperature of the motor to rise and cause the body to be damaged. When this kind of fault occurs, you can check the coils of the motor. Check whether it is caused by short circuit or open circuit, and solve it by replacing the motor.
Fourth: There are various noises in the motor
The noise of the high-speed motor is very small during normal operation, and the operation is stable and the speed is uniform. Only when the high-speed motor is loaded or foreign objects enter the interior of the motor will there be various collision sounds or discontinuous and irregular mechanical noises. At this time As long as the impurities inside the motor are cleaned, it can be solved very well.
Fifth: The motor runs too slowly
The running speed of the high-speed motor itself is extremely fast. When the running speed of the motor is too slow, it is necessary to investigate the occurrence of a fault. By checking the bearing runner to see if there is a lack of lubricating oil or if there is a problem with the circuit, you only need to check it according to the corresponding problem. The problem can be solved by adding lubricating oil or testing each line for repair.
The above is the introduction of various common faults of high-speed motors and the corresponding maintenance methods. Through the introduction of the above five points, it can be seen that most of the motor faults are caused by improper use or untimely maintenance in daily life. Therefore, when using high-speed motors It is necessary to understand its working principle in detail before using it, and it is necessary to strengthen the maintenance in daily use, and to reduce the failure rate and improve the life of the motor by choosing a domestic professional high-speed motor.
