Design and Analysis of High Torque/Power Density Permanent Magnet Synchronous Machines

---

Introduction:

Permanent magnet synchronous machines (PMSMs) have become a key technology for transportation electrification, industrial drives, and advanced automation systems. The growing demand for compact and lightweight energy conversion systems has stimulated extensive research on improving the torque and power densities of PMSMs. In recent years, various advanced machine topologies have been proposed and investigated, including dual-rotor and dual-stator machines, axial-flux machines, and field-modulation machines. These innovative topologies offer significant potential for improving permanent magnet utilization, enhancing torque production capability, and expanding the applications of PMSMs in high-performance electric drive systems. However, further improvements in torque and power densities are increasingly constrained by thermal management capabilities. Higher current densities and electromagnetic loading inevitably lead to increased losses and temperature rise, potentially resulting in material degradation, irreversible demagnetization, and reduced operational reliability. Therefore, advanced cooling technologies and electromagnetic–thermal coupled design methodologies are essential for fully exploiting the performance potential of high torque/power density PMSMs while maintaining their efficiency and reliability. This special session focuses on the latest advances in the design and analysis of high torque/power density PMSMs, with particular emphasis on innovative machine topologies, electromagnetic design and optimization, multiphysics analysis, and advanced thermal management techniques.

The topics of interest include, but are not limited to:

1. Novel topologies and electromagnetic design of high torque/power density PMSMs
2. Dual-rotor, dual-stator, and axial-flux permanent magnet machines
3. Advanced winding configurations and permanent magnet arrangement optimization
4. Electromagnetic–thermal coupled modeling and multiphysics design optimization
5. Loss analysis and advanced cooling technologies for high power density machines
6. Torque ripple reduction, vibration suppression, and demagnetization analysis
7. Multi-objective optimization and experimental validation of high torque/power density PMSMs
