Websynchronous: [adjective] happening, existing, or arising at precisely the same time. WebMay 27, 2024 · Dr. Karl Hoffower, DC, CRL explains the difference between vibration peaks that are synchronous versus non-synchronous. The driver of a rotating asset is often referred to as the 1X or “one time”. This is the initial first frequency you should look for on a vibration spectrum graph. Many faults are harmonics of the 1X (one time).

WebThe synchronous speed of an AC motor is determined by the frequency of the source and the number of poles. The RPM is calculated by multiplying the frequency times 60 and dividing by the number of pairs of poles. This was explained in Chapter 6. Some motors are designed to operate at synchronous speed. Actual speed of the induction motor will ... WebNov 1, 2014 · The vibration frequency 2400CPM is dominate all over the drive train. With the high vibration the axial motor non drive end is the highest followed by the pinion non drive end. You could say the shaft has like a tuning fork effect. I had a look at information on the exciter and it has 6 diodes and was just looking for a clue.

WebFeb 23, 2024 · The subsynchronous resonance (SSR) is an important problem in the power system, and especially the series compensated transmission lines may cause SSR in the turbine generators, such that it leads to the electrical instability at subsynchronous frequencies and potential turbine-generator shaft failures. Taking the Vietnamese … WebUsually features a spectral signature characterized by the presence of synchronous vibration (rotating speed harmonics), subsynchronous vibration (0.5x RPM) and non-synchronous (1.5x RPM, 2.5xRPM, 3.5x RPM, etc.) . These frequencies sometimes can be modulated by the FTF. Looseness between bearing and shaft.

Weba reduction in vibration as a favorable change, however, the underlying cause of the vibration change and its significance would be missed. Synchronous and Nonsynchronous The excitation forces acting on a machine can be separated into two broad categories: synchronous and nonsynchronous.
