ESTUDO DE VIBRAÇÃO EM MOTORES ELÉTRICOS

Abstract

The procedure on predictive maintenance methods is increasingly present, in order to avoid unexpected ones, increase equipment efficiency, reduce unnecessary expenses and increase machine life. The work in question was developed using vibration analysis as a model of predictive maintenance in electric motors. The use of a Vibxpert II analyzer from PRÜFTECHNIK for data collection was the methodology adopted. The analysis was done by means of a motor with two disks, and data from the balanced motor and later from the motor were collected with an additional unbalanced mass. The effects of resonance and transmissibility along with the centripetal force generated by the imbalance were discussed. Therefore, it is of great importance to avoid the frequency at which the resonance occurs to reduce the effects of premature wear of engine parts, and it is essential to keep the equipment balanced to reduce the vibrations of the engine and of any attachment assembly.
