Due to the wide application of motors in industrial fields, they need to work in harsh environments. In some fields, motors need to be frequently operated 24 hours a day. It is precisely because of the work requirements in these fields that if you want to ensure the normal progress of production, the motor must be equipped with corresponding protection equipment to reduce the occurrence of its failures. As a protection device for motor protection, the basic performance of the motor protector is also developed for motor failure.
At present, there are many types of motor protectors on the market, and various models and specifications are also available. In order to meet the different needs of different users, manufacturers will derive more series of related products. Before choosing the corresponding protector, the user should proceed from the actual needs and reasonably choose the protection function and protection method. In this way, a good protection effect can be achieved and the operation reliability of the equipment can be improved.
Regarding this point, in fact, we can start from the analysis of the basic performance of the motor protector. Although there are many types of motor protectors on the market, in the final analysis, they are mainly focused on the problems that often occur in motors. During the daily operation of the motor, faults such as overload, lack of phase, blocked rotor, short circuit, overvoltage and undervoltage, leakage, three-phase imbalance, etc. will occur due to various reasons. Therefore, the motor protectors on the market also mainly focus on the corresponding power-off protection when these faults occur.
