Emerging Electric Machines and Drives for Energy Conversion

Dear Colleagues,

The global transition toward sustainable and efficient energy systems is accelerating the development of advanced electric machines and drive technologies. Electric machines are at the heart of modern energy conversion systems, enabling electrification across transportation, renewable energy generation, industrial automation, and smart infrastructures. Recent advances in power electronics, magnetic materials, control algorithms, and digital design tools have opened new possibilities for higher efficiency, power density, reliability, and functionality. At the same time, emerging applications—such as electric and hybrid vehicles, aircraft electrification, offshore wind energy, robotics, and distributed energy resources—pose stringent requirements that challenge conventional machine topologies and drive solutions. Addressing these challenges requires interdisciplinary research that integrates machine design, modeling, control, power electronics, and system-level optimization.

This Special Issue aims to provide a focused forum for presenting recent theoretical, computational, and experimental advances in emerging electric machines and drive systems that enable efficient and intelligent energy conversion. Contributions that address electric machines and drive systems by combining machine design, modeling, control, power electronics, materials, and system integration aspects are particularly encouraged. By bringing together researchers and practitioners from academia and industry, this Special Issue aims to highlight innovative concepts, validated methodologies, and emerging research directions that enhance the performance, reliability, and applicability of electric machines and drives, supporting the broader electrification of energy conversion systems.

In this Special Issue, original research articles and reviews are welcome. Research areas may include, but are not limited to, the following:

• Novel electric machine topologies (PM, reluctance, hybrid-excited, multiphase, axial-flux, transverse-flux, high-speed machines, etc.);
• Modeling, simulation, and digital twin approaches for electric machines and drives;
• Advanced drive systems and control techniques for electric machines;
• Fault-tolerant electric machines, condition monitoring, and diagnostics;
• Thermal management, advanced materials, and manufacturing technologies for electric machines and drive systems;
• Integration of power electronics with electric machines;
• Electric machines and drives for renewable energy systems and transportation electrification;
• Emerging and novel applications of electric machines and drive systems.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
