Samarium-Cobalt magnets have the best Br temperature coefficient (-0,035%/°C) granting the absolute higher available induction above 150°C working temperature. Despite a higher cost than other magnetic materials, SmCo provides an outstanding combination of high energy, thermal stability and corrosion resistance. Protective coatings are generally not required except for particular applications.

Samarium Cobalt Arc Segment SmCo Magnets for Motor

The typical final shapes such as blocks, cylinders, rings and arcs are obtained by cutting and grinding processes of pressed standard blocks or unitary compression pre-moulded part. Extremely fine tolerances can be obtained although, because of its high brittleness, it has to be handled and assembled with care to avoid chips and cracks.

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.

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. Alternator Motor Rotor Ring Permanent Neodymium Bonded Magnets

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).

High Temperature SmCo Arc Motor Magnet

The consumption of motor is the greatest among the rotating machinery. The eddy current losses are one of the worst enemies to high-speed rare earth permanent magnet motor. The eddy current will give rise to the temperature of the rare earth permanent magnet, then the magnet will be demagnetized, therefore influence the work efficiency of the motor. As the metallic material, the rare earth permanent magnet has lower electrical resistance, and it also become the direct source of eddy current losses.
