Electric gourds have abnormal noise or excessive vibrations are likely to be caused by the noise or bearing oil leakage, bearing overheating, etc. produced by the motor itself.

The noise generated by the motor itself: suddenly the sound is abnormal during operation. Check whether the motor runs in a single phase: one is that the power supply is broken, and the other is that the motor is broken. This situation must be stopped, otherwise it is easy to burn the motor; Phase current should be detected, generally not more than 10%. UNIDIDIDIDIDIDIDID: First, the power grid voltage is unbalanced; the other is that the motor stator winding has an instant short circuit; the third is that the fixed and the rotor is uneven; the fourth is that the rotor has a broken bar and a thin strip phenomenon. Electric failure, take measures as soon as possible.

Noise generated by mechanical friction: The mechanical failure of the motor is: fixed, rotor rubbing; bearing oil leakage, bearing overheating.

Fixed and rotor: Because the gap between the fixed and rotor is very small, it is often due to uneven air gaps, iron chips, burrs, and paint films in the motor. Local heat, winding damage for winding, should be dismantled and processed in time.

Bearing oil leakage and bearing overheated: mainly caused by too much or too little bearing lubricating fat, unclean fat fat, poor bearing quality, etc. Many reasons, etc., you will hear the sound of "khaki-" during operation. And observe the surface of the runway, check the relevant size and then adopt measures. In addition to the mechanical failure of the motor, you should check whether the couplet connected by the reducer should be rotated, whether the concentricity meets the requirements, and the installation foundation, shaft extension, and imbalance of the transmission unit will produce abnormal noise, and the corresponding vibration is also Increasing, the user should judge the failure of the motor with the sound they hear, and resolve it in a timely manner.
