With the increasing demand for smaller, lighter, and more affordable electromagnetic devices, there is a growing trend toward developing high-power-density transformers and electrical machines. While increasing the operating frequency is a straightforward approach to achieving high power density, it can lead to significant power loss within a limited volume, resulting in excessive temperature rise and device degradation. Therefore, it is crucial to design high-power-density electromagnetic devices that exhibit low power loss and efficient thermal dissipation to address these challenges. Advanced techniques, such as the utilization of novel and advanced electromagnetic materials, hold great promise for overcoming these issues. Specifically, nanocrystalline and amorphous magnetic materials have emerged as highly effective solutions for reducing power loss and increasing efficiency in electromagnetic devices. This paper aims to provide an overview of the application of nanocrystalline and amorphous magnetic materials in transformers and electrical machines, along with key technologies and the major challenges involved.

Permanent magnet motors (PMMs) have emerged as key components in numerous industrial applications due to their high efficiency, compact size, and robust performance characteristics. However, to attain optimal performance in PMM drives, accurately predicting and mitigating core losses is paramount. This paper aims to provide a comprehensive review of advancements and methodologies for enhancing the performance of PMM drives by integrating equivalent circuit models (ECMs) that account for core losses. Firstly, the significance of core losses in motor drives is underscored, alongside a survey of research endeavors dedicated to core loss reduction. Notably, emphasis is placed on mathematical models offering both swift computation and reasonable accuracy. Subsequently, the paper delves into the development of ECMs, focusing on approaches adept at capturing core loss effects across diverse operating conditions. Moreover, this paper explores the utilization of these improved ECMs in the design and control of PMMs to achieve enhanced performance. By integrating core loss considerations into design and control strategies, PMM drives can optimize efficiency, torque production, and overall system performance. In summary, this paper may consolidate the current state-of-the-art techniques for enhancing PMM performance through the integration of core-loss-aware ECMs. It highlights key research directions and opportunities for further advancements in this critical area, aiming to foster the development of more efficient and reliable PMM-based systems for a wide range of industrial applications.

“…Other works ( [18][19][20][21]) have treated the same problem; however, the apparatuses used are similar to the ones previously referred to. An apparatus capable of 3D excitation and measurement was treated in [22], consisting of 3D coil systems for both the excitation and the measurement. Due to its design, the apparatus does not allow the application of mechanical stress.…”

Ferromagnetic materials exhibit nonlinear magnetic behavior, and many are anisotropic. Their magnetic characterization requires a mappingin excitation and measurementof the magnitude and direction of the magnetic field H or magnetic induction B. While many previous works have treated different parts of the characterization problem, the question of measurement reliability was not always adequately addressed. The present work relies on key assumptions made in characterization experiments to propose three criteria that form a necessary and sufficient condition for reliable measurements: (1) material properties are assumed homogeneous in the measurement region (uniformity criterion), (2) measured H is assumed to be equal to that giving rise to the measured 𝑩 (correspondence criterion) and (3) B&H directions are assumed known (direction criterion). Both theory and simulation are used to quantitatively assess the fulfillment of these assumptions using various apparatuses found in the literature along with new setup designs. Both alternating and rotating field loadings are considered for linear and nonlinear behaviors, using isotropic and anisotropic materials in both 1D and 2D excitation and measurement systems, with and without applied mechanical stress. The derived criteria are then used to establish guidelines for accepting, rejecting, and improving experimental apparatuses and offer clear insight into the measured data. In general, and when the application allows it, surface measurements of both B&H are recommended, 1D excitation systemsthough limited to certain applications -fulfill the criteria the most, and finally, while the excitation can be 1D or 2D the measurement should always be 3D.
