When the three-phase asynchronous motor is in normal operation, the fuselage should be smooth, and the sound should be low and even; When the motor vibrates, we first distinguish whether it is caused by the motor itself, or the transmission device is badly installed, or the mechanical load is transmitted Handed over, and then ruled out on a case-by-case basis.

       If yesThree-phase asynchronous motorThe vibration caused by itself, in the production practice, most of it is caused by poor dynamic balance, poor bearings, bending shaft or uneven installation foundation of the motor, loose fasteners and other reasons. Vibration creates noise and additional load.

       It can be found by listening to the sound, when the larger buzz, indicating that the current is too large, may be caused by overload or three-phase current imbalance, when the motor single-phase operation, the buzz will be larger; When it makes a grunting sound, it may be caused by damage to the bearing ball; When the uneven rubbing sound is emitted, it is often due to the sound of the rotor and the stator rubbing, that is, the sound of the sweep, and should be shut down immediately.
