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.
What is the Advantages of Laminated 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.
The fewer the eddy current loss becomes, the lower the heat generates to enhance higher efficiency. Nowadays the demand of laminated rare earth magnets has been going up, because aerospace, industrial markets and promising EV especially are dedicating to pursuing the balance between motor power and heat.

Samarium Cobalt (or SmCo) magnets are strong permanent magnets made of an alloy of samarium and cobalt. They are known for their high magnetic strength, exceptional temperature resistance, and reliable performance without oxidation protection. As a result, they are more suitable for certain applications than Neodymium magnets.
Machining & Magnetization
Samarium Cobalt magnets offer strong resistance to demagnetization. All Samarium Cobalt magnets cannot be formed with conventional drilling, turning or milling processes, and must be ground before they are magnetized. Additionally, large or complex assemblies are usually magnetized prior to assembly. Standard tolerances for Samarium Cobalt magnets are +/-.005 for ground dimensions.
Samarium Cobalt magnets (SmCo) may be weaker than NdFeB magnets at room temperature but SmCo will often outperform NdFeB above +150 to +180 deg C (subject to the application and grade). SmCo magnets are ideal for aerospace, automotive, sensor, loudspeaker, motor and military applications. In mission critical applications they are an ideal first choice. SmCo magnets offer minimal change in magnetic output over a small temperature change (with far less variation than NdFeB or ferrite; only Alnico is better). The Low Temperature Coefficient (LTC) versions have less variation in magnetic output with temperature change (due to added Gd and Er). SmCo magnets performance over a massive range of temperatures (from near to -273 deg C up to +350 deg C). The H versions Sm2Co17 have higher Hci and operate up to +350°C rather than +300°C.SmCo and NdFeB could be interchangeable e.g. SmCo30 should perform very similarly to N30 at ambient temperature.
