Vibration in Electric Motors - XYO balancerTraduire cette page

    A basic electric motor has a magnetized stator that surrounds a rotor; the magnetic interaction between the two causes the rotor to spin. Faults in motors can develop due to resonances, imbalance, misalignment and foundation problems or improper mounting. These faults can lead to bearing failures and cause vibration.

    Electrical and Mechanical Noise in Motors

    An electrical noise could be reduced by fitting a capacitor or a choke coil to a motor terminal part. However, in order to reduce spark or voltage generated by a spark, these parts are to be fixed to the armature, which enables to eliminate the noise more effectively; fixing parts closer to the armature sometimes contributes to the lower cost policy.

    01.10.2014 · The electrical power quality analysis showed that; the total harmonic distortion (THD) increases by about 1–2% due to the effect of bad motor vibration, and the 5th and 7th harmonic contents also increased by about 0.5–1.0%. Also the bad motor vibration caused large values of instantaneous flicker. These results indicated that the bad motor support causes many dynamics .
