Vibroacoustic diagnosis technique for electric motors in residential environment

摘要

The paper deals with the vibroacoustic perturbations issues,generated by the induction electric motors and brushless in residential environment.Two situations are analyzed: one in the componence of a chiller,used in the generation of thermal agent,and the other in the componence of an air handling unit,both destined to reach ambient comfort.Through diagnosis,the level of the acoustic and vibrating perturbations,generated by the electric motors in the componence of heating and air conditioning equipment are detected.Harmonic analysis highlights the level and the frequency of the perturbations and the conclusions contains the technical solutions to avoid their occurrence.
