New Advances and Applications in Electromagnetic Machines

Dear Colleagues,

Electric machines are evolving rapidly to meet the growing demands of electrification across various sectors, including industry, transportation, domestic life, defense, and biomedical systems. As the global shift toward net-zero emissions accelerates, there is an increasing demand for electric machines that exhibit high torque/power density, excellent energy efficiency, enhanced thermal management, compact integration with power electronics, and minimal environmental impact.

Research and development efforts are pushing the boundaries of electromagnetic machine design, modeling, and manufacturing. In particular, additive manufacturing is unlocking unprecedented 3D structural freedom, enabling integrated thermal-magnetic design and complex topologies that were previously unachievable. Likewise, high-speed electric machines are promoting system miniaturization and power density gains, although they require careful consideration of coupled electromagnetic, mechanical, control, and thermal interactions. Furthermore, rare-earth-free and ironless machine topologies are emerging as key solutions to reduce material dependence and mitigate long-term environmental concerns. The growing use of multiphysics simulations, topology optimization, and AI-assisted design methodologies is also reshaping machine development paradigms, enabling high-fidelity performance prediction and accelerating the creation of innovative electromagnetic architectures.

This Special Issue, entitled “New Advances and Applications in Electromagnetic Machines,” aims to present the latest advances in the design, analysis, optimization, and application of next-generation electric machines. We invite original research articles, critical reviews, and application-driven case studies that address both fundamental challenges and emerging opportunities in areas such as electric propulsion, robotics, aerospace, renewable energy systems, and future mobility platforms.

Topics of interest include, but are not limited to, the following:

(1) Permanent magnet machines;

(2) Rare-earth-free and ironless machines;

(3) High-speed and high-frequency machines;

(4) AI-assisted and data-driven design optimization;

(5) Coupled multiphysics design: electromagnetic, thermal, structural, acoustic;

(6) Advanced manufacturing techniques for electric machines;

(7) Advanced electromagnetic materials for electric machines;

(8) Machine drive control.

We particularly encourage submissions that include experimental validations, control-integrated design strategies, or innovative electromagnetic topologies applicable to modern inverter-fed systems. Contributions may address theoretical insights, simulation methodologies, system-level integration, or application-oriented challenges.

This Special Issue aims to serve as a platform for collaboration across academia, industry, and research institutions. We encourage contributions that reflect the interdisciplinary nature of electromagnetic machine systems and highlight recent progress from both research and industrial perspectives. We look forward to receiving your submissions that will help drive innovation in the design and application of next-generation electric machines.
