Soft magnetic composite materials and their applications in electrical machines

Soft magnetic composite materials (SMCs) have undergone a significant development and have been in a range of new applications in the past decade. Based on the experiences of the SMCs research group at University of Technology, Sydney, and with the analysis of many references, a comprehensive survey on the development and application of SMCs in electrical machines is presented in the paper. Both successful experiences and existing difficulties are reviewed and analyzed. It is believed that the application of SMCs is preponderant in the small motors with complex topologies. Possible further work required for the commercial success of SMCs machines is also proposed
