Sintered SmCo magnets, i.e. Sintered samarium cobalt magnets, are those permanent magnetic materials that based on a hexagonal crystal structure (1:5 type SmCo magnets) or a rhombohedral crystal structure (2:17 type SmCo magnets), and they are manufactured through a powder metallurgy process. They contain two basic elements samarium and cobalt. The samarium element can be substituted by a portion of other rare earth elements including praseodymium (Pr), cerium (Ce), gadolinium (Gd), erbium (Er), etc. the cobalt element can be substituted by a portion of iron (Fe) element to increase the magnets’ saturation magnetization (Ms). in order to control the microstructure and the microchemistry so as to meet required performance, it is also critical to add a small portion of copper (Cu), zirconium (Zr), titanium (Ti), etc.
The magnet made by segmentation technology can be called laminated magnet, layered magnet, split magnet and segmented magnet. For magnet segmentation technology, the whole magnet will be segmented into several pieces, then processed into specific shape and dimension after glued together by special isolation glue. rare earth smco motor magnet
According to many simulation cases and actual products, the magnet segmentation technique has excellent performance to prevent the eddy current. With the increase of segment, the eddy current losses of permanent magnet significantly decreased. Magnet segmentation technique has been already applied in the NdFeB and SmCo magnet.
