There is little need to prove the importance of the subject matter. Electrical machines are the most important components of both the industrial and the commercial world. They are at the heart of the new industrial revolution brought forth by the development of electromobility and renewable energy systems. Today’s electric motors must meet the most stringent requirements of reliability, availability, and high efficiency in order to match (and exceed!) the useful lifetime of power electronics in the complex system application and to compete in the market under ever-increasing pressure to deliver the highest performance criteria. Today, thanks to the application of highly efficient numerical algorithms running on high-performance computers, it is possible to design electric machines and entire drive systems faster and at a lower cost. At the same time, progress in the field of material science and technology enables the development of ever more complex motor designs and topologies. Therefore, the purpose of this Special Issue is to contribute to the development of electric machines. We encourage scientists and application engineers to present the results of their research in the field of design and application of electric machines from the smallest ones with powers up to several watts, to the largest at megawatt power. We are pleased to accept original research as well as review articles.vTopics of interest for publication include but are not limited to: Simulation tools, modeling, and analysis of electrical machines; New design methods of electrical machines; Optimization of electrical machines; Electrical machines for EVs and HEVs; Power electronics used for electrical machines; Supply and control of electrical machines; New technologies, materials, devices, and systems for electrical machines; Linear drives for transportation.
