Professional production and wholesale house motors, motor in the use of the process we will encounter a sudden stop in the process of running the problem.
First of all, pay attention to the load is there any big change, there is no mechanical stuck, check whether there is something blocking the load, if there is a foreign body to clean up in time.Make a rough judgment about whether there are major mechanical problems, then consider the electrical aspects.
1. Disconnect the motor and the load coupling as far as possible when possible, and then move the motor shaft by hand to see if there is any problem of stuck, and first rule out if there is any shell collision inside the motor or if the bearing has no dry oil wear.If the equipment has been put for a long time, it is necessary to check whether there is oxidation, rust and corrosion.
2. If it is the newly assembled motor and load, it is necessary to check whether there is a deviation in one direction during the assembly of overcharge, such as no horizontal alignment, concentric misalignment, etc., or the rotor and rotor are too tight and loose.
3. If the motor has a driver or something like that, check the historical alarm record of the driver to see what the alarm content is, so as to deal with it accurately and timely.
4. For the newly installed system, it is necessary to reconsider whether the motor specification has been selected as small. After running for a while, the overload problem will occur.
