Definition An order tracking analysis consists in post processing vibroacoustic calculations or measurements to extract the acoustic noise or vibration levels of some excitation frequencies proportional to speed (the so-called […]
Definition An electrical order is the ratio between a frequency with the fundamental electrical frequency : begin{equation*} k_{e} = f / f_{e} end{equation*} Similarly, the mechanical order is the ratio […]
Introduction This article reviews the techniques to mitigate noise and vibrations due to magnetic forces in electrical machines (electromagnetically-excited noise and vibrations) based on EOMYS Engineering consulting experience. To go […]
