Abstract: The electrification of transportation and industrial sectors is driving the demand for high-power-density electric machines, which are essential for compact, efficient, and lightweight energy conversion systems. Achieving high power density in motors and generators requires a multidisciplinary approach that integrates advanced materials, innovative design techniques, and robust thermal management strategies.
Recent advancements in permanent magnet synchronous axial flux motors and Halbach array configurations have enabled significant improvements in volumetric torque and efficiency. However, these designs introduce critical materials challenges, including demagnetization risks at elevated temperatures, the need for high-performance electrical steels, and the development of insulation systems capable of withstanding high voltages and temperatures up to 350°C.
Applications span electric vehicles, aircraft propulsion, and renewable energy systems, where weight and volume constraints are paramount. The ongoing transition to high-voltage architectures and the adoption of rare-earth-free magnets present additional opportunities and challenges for sustainable machine development.
This presentation will provide a panorama of current solutions, emerging materials, and future research directions for high-power-density electric machines, emphasizing the interplay between materials science, design optimization, and real-world applications.
