Electrical machines play a crucial role in all industry fields and power generation, as well as final energy use and domestic applications. In this modern reality and under the global need for CO₂ emission reduction, electric motors, transformers and generators are continuously evolving, aiming for higher efficiencies simultaneously with more reliable operation. In the field of energy generation and consumption, great changes are taking place. An increasing number of electrical machines are working together with power electronics, while a significant portion of the generated power is covered by renewable energy harvesting. A large number of multiterminal HVDCs are planned in the transmission systems, with new transformers specially designed for them. Moreover, regarding the end use of electric power, there are many developments, such as high-efficiency motors, motors for electric vehicles, aircraft drives, and new technologies such as reluctance, permanent magnets, and superconducting machines. The electrical machine operation and condition monitoring in the era of the industry 4.0 will be equally innovative. New techniques for signal processing, artificial intelligence, big data analysis, new sensors, and wireless and real time monitoring devices, among others, will be used for the control and supervision of electrical machines. This Special Issue will focus on all the new advances related to electrical machines, such as novel designs, new applications, condition monitoring, etc. Papers related to modern advances in electrical machines which will shape the future in this field are most welcome.
