Advancements in Design and Control of High-Efficiency Electric Motors

Dear Colleagues,

Recent advancements in electric motor technologies have facilitated their integration across a wide range of modern applications, including pumping systems, wind energy conversion, electric vehicles, rail traction, and fault diagnosis. As the demand for energy-efficient, reliable, and intelligent electric drive solutions continues to grow, electric motors are becoming essential components in industrial, transportation, and renewable energy sectors.

Key topics of focus include novel control strategies, optimization techniques (such as AI-based tuning and predictive control), robust design methodologies, and diagnostic frameworks that enhance motor performance under various operating conditions. Special attention is given to sensorless control, torque ripple minimization, fault tolerance, and energy management strategies. Furthermore, innovations in motor design, including multiphase and high-speed machines, are explored, along with their adaptability to application-specific constraints.

This collection of work brings together multidisciplinary research efforts, providing a comprehensive overview of the challenges and solutions involved in deploying electric motors across diverse fields, paving the way for more intelligent, sustainable, and integrated motor-driven systems.

We invite authors to submit original research papers and review articles for publication in this Special Issue of Energies. Topics of interest include, but are not limited to, the following:

• Design and optimization of high-efficiency electric motors;
• Advanced control techniques for electric motors (e.g., DTC, FOC, MPC);
• Artificial intelligence and machine learning in electric motor control;
• Torque ripple reduction and dynamic performance optimization;
• Fault detection and diagnosis in electric motor systems;
• Sensorless control strategies for electric motors;
• Energy-efficient design and operation of electric motors in industrial applications;
• Multiphase and high-speed electric motor design;
• Electric vehicle (EV) motor design and control strategies;
• Electric motor applications in renewable energy systems (wind, solar, etc.);
• Power density optimization in electric motor design;
• Robust control methods for motors under parameter variations;
• Integration of electric motors in smart grid and renewable energy systems;
• Advanced motor topologies: PMSM, IM, BLDC, DFIM, etc.;
• Health monitoring and predictive maintenance of electric motors;
• Control optimization algorithms for motor-driven systems (e.g., GA, ACO, PSO);
• Electric traction systems and railway motor drives;
• More Electric Aircraft (MEA) propulsion system design and control;
• Energy management in electric motor-driven systems.
