Comparison of normative limits for electromagnetic emissions of electric machines and drives to use in different applications

Electric machines and power drives of various sizes and ratings are fundamental elements in many applications, such as electric appliances, electric propulsion, medical systems, all with specific limits of electromagnetic emissions, different from those of the original EMC product standards. As compliance should be assessed and guaranteed during design and procurement, this work compares the conducted and radiated emission limits and discusses the variability of results for the respective test setups and measurement methods, including the most relevant source of uncertainty.
