To ensure the safe operation of the motor, corresponding motor protectors are usually installed in the system to avoid adverse effects of various factors on the motor. But the prerequisite is to choose an appropriate motor protector. Is there any technique to refer to in this regard?
There are many factors to consider when selecting a motor protector, such as working conditions, motor performance, etc. For example, in situations where the working conditions are not high and the motor operation control is relatively simple, as long as a normal type protector is selected for independent operation of a single machine motor, it is sufficient. Because ordinary protectors can already provide comprehensive protection for the motor, and their structure is relatively simple, making installation, operation, and replacement more convenient.
But if the working conditions are harsh and the reliability requirements for motor operation are high, then it is necessary to replace it with a mid to high end and fully functional intelligent motor protector. For some special motors, their protection also has special requirements. For explosion-proof motors, corresponding explosion-proof protectors need to be used to ensure absolute safety of the motor.
