Driven by the evolution of electric drive systems in electric vehicles, aerospace, and industrial machine tools, high-speed operation has become a key direction in motor development. While progress in emerging manufacturing technologies and novel materials has partially alleviated the inherent contradiction between electromagnetic performance and mechanical strength in high-speed rotors, traditional approaches—including geometric optimization of flux bridges and center posts, macroscopic material replacement, and structural reinforcements—tend to make the multi-physics trade-offs increasingly complex. The application of dual-phase soft magnetic laminate presents a promising alternative. By achieving localized regulation of rotor characteristics, this approach effectively decouples electromagnetic performance from mechanical constraints. Although the technical merits have been verified, the existing literature lacks a systematic overview of the fabrication technologies and application status of dual-phase soft magnetic material laminate. Hence, this paper aims to provide a comprehensive review of recent fabrication approaches and development trends, thereby serving as a fundamental reference for researchers aiming to integrate this material into innovative rotor topologies.
