Soft magnetic composites (SMCs) are successfully manufactured from insulated iron powder using the powder metallurgy compaction process. The isotropic nature of the SMC material combined with the unique shaping possibilities of the P/M compaction process opens up new opportunities for the designer of electromagnetic devices. SMC parts can be designed and manufactured with intricate shapes, smooth curvatures and excellent surface finish. In order to take full advantage of the SMC concept, redesign from today's 2-D steel laminate solutions, to new SD-designs is required. The fundamental concept of SMC materials and their processing is presented along with design concepts and prototypes. Motor design issues are highlighted. Finally some examples of commercial products are presented. (3 References).
