For this reason, several papers have been published to analyze the natural frequencies, electromagnetic force, vibration and acoustic noise. In order to avoid such noise and vibration, it is necessary to estimate the amplitude of the radial electromagnetic forces as well as the natural frequencies of the structure. Then the first aim of this work is to reach a wide knowledge how the levels of noise and vibration generated by the induction motor vary under different working conditions.Д®lectromagnetic noise is generated when the natural frequencies of vibration of induction motors match or are close to the frequencies present in the electromagnetic force spectrum. Less use of iron in the stator not only yields to a weaker structure but also higher field levels, thus causing higher magnetic forces, which yields to increased vibrations. Since the encasing is less stiff, the machine becomes more sensitive to vibrations and noise. Economic considerations force to use less active material.

It saves time and effort lost in doing the calculations by the Manual Method (Equations and Tables Method) As we see in the previous Articles.Lately, as engineers have recognized the importance of having a high-quality working place, the effect of the noise and vibration emitted by inverter-fed induction machines has become a subject to study.Provide the primary risk values automatically in the final results report and make a comparison with the tolerable risk values and assign the need for lightning protection based on this comparison for each type of loss.Provide comments as a help guide which explains the meaning of the used parameters, factors and terms in this excel sheet.Provide two maps for assistance in determination of lightning ground flash density (Ng) and isokeraunic number (thunder storm days/year).Provide all tables of IEC 62305-2 as dropdown menus for automatic determination of parameter/factors values for the case under design,.List all input data (in green cells) that must be known to determine the need for lightning protection,.Calculate the collection areas for different shapes (Rectangular, cylindrical,вЂ¦) basic and adjacent structures,.Calculate the collection areas for basic and adjacent structures, power lines (if any and up to two lines) and telecommunication line (if any),.
