How much do you know about the common sense of motor protection? Let's follow the editor of All metal drilling motor manufacturers to have a brief understanding of it!
1. The development status of motor protection: The motor protector has been developed from the mechanical type in the past to an electronic type and an intelligent type, which can directly display the current, voltage, temperature and other parameters of the motor, with high sensitivity, high reliability, multiple functions, and convenient debugging. , the types of faults after the protection action are clear at a glance, which not only reduces the damage of the motor, but also greatly facilitates the judgment of the fault, which is beneficial to the fault handling of the production site and shortens the recovery time. In addition, the motor eccentricity detection technology using the motor air-gap magnetic field makes it possible to monitor the motor wear state online. The curve shows the changing trend of the motor eccentricity, and can early detect bearing wear and inner circle, outer circle and other faults. Early detection, early treatment, to avoid sweeping accidents.

2. The principle of protector selection: Reasonable selection of motor protection devices can not only give full play to the overload capacity of the motor, but also avoid damage, thereby improving the reliability of the electric drive system and the continuity of production. The specific function selection should comprehensively consider factors such as the value of the motor itself, the type of load, the use environment, the importance of the main equipment of the motor, and whether the withdrawal of the motor has a serious impact on the production system, and strive to be economical and reasonable.
The above is the editor of All metal drilling motor manufacturers: a brief introduction to the common sense knowledge of motor protection.
