Abstract

Electrical machines are fundamental to a wide array of applications, ranging from industrial automation and transportation to renewable energy systems and consumer electronics. As global energy demands surge alongside the pressing need for environmental sustainability, the development of efficient, reliable, and eco-friendly electrical machines has become a critical focus. Recent advancements in this field have introduced innovative approaches that prioritize energy efficiency, resource optimization, and compact designs without compromising performance. This review delves into the latest trends in electrical machine design, emphasizing the adoption of sustainable materials, the implementation of advanced modeling and manufacturing techniques, and the integration of digital technologies such as artificial intelligence (AI) and the Internet of Things (IoT). Additionally, this article discusses the challenges of balancing cost, performance, and environmental impact, while exploring promising future directions such as hybrid machine technologies, enhanced thermal management systems, and the role of electrification in reducing carbon footprints. The findings aim to provide insights for researchers, engineers, and policymakers striving to meet the dual objectives of high performance and environmental responsibility in electrical machine innovation.
