As the world embarks on a path toward electrification and strives to achieve net-zero greenhouse gas emissions, the role of electrical machines becomes increasingly vital across various applications. The urgent need for decarbonization and improved energy efficiency has directed attention to rare-earth-free electrical machines as a promising solution. These technologies offer a sustainable alternative to permanent magnet-based machines, which rely heavily on rare earth materials like neodymium and dysprosium. The extraction and processing of these materials result in hazardous by-products that cause significant ecological harm, particularly near mining sites and refineries.
