Special Issue Information

Dear Colleagues,

Rotating electrical machines are widely used in key sectors such as industry, energy, and transportation, with a growing presence in modern mobility applications. Some of these applications pose challenges that traditional design and maintenance approaches fail to address. In the digital era, with the increasing demand for sustainability, new design and maintenance paradigms are emerging. In this context, the design of electrical machines, both in their traditional and more innovative forms, represents an interesting research topic. Particularly, research on data-based methods, innovative optimization approaches, PM-less designs, and novel machine topologies contributes to fulfilling challenging design and sustainability goals. Additionally, maintenance strategies such as fault diagnosis and the condition monitoring of electrical machines currently face similar challenges. Data-driven approaches leveraging machine learning algorithms continue to attract significant research interest. This trend, together with advanced signal processing tools and innovative sensing technologies, contributes to the development of novel monitoring and diagnosis methods.

The aim of this Special Issue is to present the latest advancements in emerging paradigms for the design and maintenance of electrical machines. Original research on more traditional approaches, as well as review articles, are also welcome. Possible research topics include, but are not limited to, the following:

  • The design of electrical machines for emerging applications;
  • Special electrical machines;
  • The design optimization of electrical machines;
  • Data-driven design;
  • The simulation of abnormal operation in electrical machines;
  • Smart sensors for electrical machine maintenance;
  • Advanced signal processing tools;
  • Data-driven fault diagnosis and condition monitoring;
  • Vibration monitoring;
  • Electrical signature analysis.

Amorphous soft magnetic materials (AMMs) have demonstrated significant advantages in electric machines due to their low core losses, high permeability, high tensile strength, and superior energy efficiency at high operating frequencies. Despite these benefits, their adoption in electric vehicle (EV) motors remains limited. This review explores the key technological, economic, and industrial barriers preventing the widespread use of AMMs in EV applications. An overview of the AMM fundamentals, including the material composition, manufacturing processes, and recent advancements, is first presented. To quantitatively assess their potential in traction applications, a numerical study is conducted on two 5.5 kW synchronous reluctance machines with identical geometries, employing AMM and conventional silicon steel stators, respectively. The machines are compared in terms of electromagnetic torque and efficiency, highlighting the impact of AMM properties on machine performance. These results are discussed alongside the findings from the existing literature to evaluate the core loss reduction, electromagnetic behavior, mechanical robustness, and thermal considerations. Special attention is given to the emerging commercial applications of AMMs in EV motors, which have only recently begun to materialize. Finally, the study highlights the gap between academic research and industrial implementation and identifies critical research areas needed to accelerate AMM adoption. Full article
