The non-destructive testing technology of motor eccentricity based on the motor magnetic field makes it possible to detect the motor damage condition online. The trend analysis of the value reflecting the motor eccentricity level is displayed through the curve chart, and the change of the value in 2 years is recorded. The rolling bearing problem can be found early, ensuring early detection and early treatment to avoid the occurrence of bore scraping accidents. Therefore, the application of motor overload protector is becoming more and more common. How to chooseMotor protectorIt is also one of the issues that everyone is concerned about.

The purpose of using motor maintenance equipment is to enable the motor to fully utilize its load capacity and avoid damage, and to improve the stability of the pneumatic transmission system and the continuity of production. When the maintenance requirements can be met, simple maintenance equipment should be considered first. When simple maintenance equipment cannot meet the requirements, or when higher requirements are put forward for maintenance functions and features, complex maintenance equipment should be considered to ensure the consistency of rationality and stability.

Detailed function selection should be based on a comprehensive consideration of the motor's own value, load conditions, environmental quality, the motor's importance, whether withdrawal from work will cause serious impact on the production system and other factors, in order to ensure economic efficiency.
