Many times we are judged by the sound of the three-phase asynchronous motor when it is running, whether it is running normally; Different sounds correspond to different problems. Today, Senli Motor Xiaobian will take you to a simple understanding of why the motor will produce abnormal sounds when it is running, and the corresponding policies.

        1.Mechanical friction (including stator, rotor friction), or coupling and motor friction;

        2.Phase missing operation;

        3.Rolling bearing oil shortage or damage;

        4.Wiring error;

        5.The shaft extension end is bent, or the shaft is damaged;

        6.Coupling loose, rotor, pulley balance is not corrected, pulley, coupling eccentric;

        7. The installation base is unbalanced or defective.

        When these problems arise,Three-phase asynchronous motorIn the operation will produce different degrees of noise, then we need to check the cause.

        1.Check the gap between the rotating part and the stationary part, find out the reason for the friction, and correct it. When the motor rotor is pulled out, the rotor must be lifted to prevent friction between the fixed and rotor cores.

        2.First of all, you can check the power supply, if the power supply is normal, then check the motor, and repair it;

        3.Pay attention to cleaning and checking the bearing, bearing damage, change the bearing. Find out the cause and correct it;

        4.Straighten the shaft, or replace the rotor;

        5.Find out the loose place, tighten the bolt, and correct the balance and concentricity of the rotor, pulley and coupling;

        6.Check foundation and bottom plate fixation and correct;
