There are many causes of motor vibration, generally common2Polar,4Polar,6Pole motor, yes8supergradeThree-phase asynchronous motorVibration will not be caused by the quality problem of the motor itself. Today, Senli Motor Xiaobian will take you to a simple understanding of the three-phase asynchronous motor that generates vibration and how to find the cause.

       1Remove the motor from the load, empty test the motor, and detect the vibration value. If the motor air test vibration does not exceed the standard, the load vibration exceeds the standard, there are two reasons:

       ①The correction deviation is large;

       ②The residual unbalance of the rotating part (rotor) of the main engine overlaps with the residual unbalance of the motor rotor, and the residual unbalance of the whole shafting at the same position after the butt joint is large, and the exciting force generated is large, causing vibration.

       2Only one or two diagonal vibration of the four feet exceed the standard, and the anchor bolts are tightened to cause vibration caused by the deformation of the frame. theThree-phase asynchronous motorThe four anchor bolts are fully fastened, and the vibration value of the motor is still exceeding the standard, then check whether the coupling on the shaft extension is flat with the shaft shoulder, such as uneven, the vibration force generated by the excess key on the shaft extension will cause the horizontal vibration of the motor to exceed the standard.

       3After the rotor is dynamically balanced, the residual unbalance of the rotor has been solidified on the rotor, will not change, the vibration of the motor itself will not change with the change of location and working conditions, and the vibration problem can be handled well at the user site.
