Vibration analysis: what does it mean? plantservices

the manufacturer's average speed for that particular motor design. The actual speed of an induction motor is always lower than the synchronous speed. Be sure to consider this, especially when looking at higher frequency ranges. Using a synchronous rpm of 1,800, for example, might prompt a technician to look for something with 53 components if

A Review of Time Synchronous Average Algorithms

2 TIME SYNCHRONOUS AVERAGING Time synchronous averaging is a signal processing technique that extracts periodic waveforms from noisy data. The TSA is well suited for gearbox analysis, where it allows the vibration signature of the gear under analysis to be separated from other gears and noise sources in the gearbox that are not synchronous with that gear. Additionally,
