The SMC Technology - From Idea to Reality 2003-01-0449

The group of Soft Magnetic Composites (SMCs) have relatively recently expanded by the introduction of new materials with significantly improved low-medium frequency properties, which has made SMCs a viable alternative to steel laminations in a range of new applications, such as rotating machinery, sensors and fast switching solenoids. SMC components are successfully manufactured using the powder metallurgy compaction process. The isotropic nature of the SMC combined with the unique shaping possibilities opens up for 3D-design solutions. If carefully implemented advantages such as better performance, reduced size and weight, fewer parts and lower cost can be obtained.
In this paper the SMC concept is presented i.e. the materials, part manufacturing and electromagnetic design. Possibilities and also limitations for SMC's are highlighted, prototype motors are described and finally some examples of commercial products are presented.
