Identify the drawbacks of an electric motor using fast Fourier transform analysis

Developments and major changes in the industrial units in different dimensions come into being discourages many new methods and systems to allocate valuable place in the meantime, And efforts in the areas of deployment of such systems will move to improve efficiency and productivity has increased as a result. This research is based on methods such as, Fast Fourier analysis, curve waveform, the bearing rollers and phase angle in frequency space were analyzed, followed by imperfections and their possible origin have been nominated. After surveying data and survey results, the disadvantage caused by the unbalance of electric monetary and non-monetary alignment in transmission was measured.The vibration amplitude and phase angle errors associated with the use of changes and fixes have been identified.
