Unbalance and misalignment are two common fault conditions, but they share similar symptoms, especially in the spectrum. This presentation will discuss why we see the vibration patterns that we commonly observe, and then look more closely at the time waveform. It is common to view an “M” or “W” shape in the waveform, but that is not always the case. This presentation will explain the reason why we see those patterns, and why sometimes we do not.
