Laminated arc permanent magnets can reduce eddy current Loss in high efficiency motors.
High efficiency demands the very best materials, and the laminated rare earth magnets are proven to reduce eddy current losses in high efficiency motors. Fewer eddy current losses means lower heat and greater efficiency.
Laminated magnet is to cut the whole magnet into many small magnets, and then use specific glue to bond together. These small magnets are insulated from each other and can down lectromagnetic eddy current.
When the permanent magnet motor is running, the motor will generate harmonic and the magnet will generate skin effect, these all will bring a lot of eddy current loss. And then, the temperature of permanent magnet rises, which results in irreversible demagnetization and affects the safety and stability of motor operation. Therefore the design of laminated magnet can easily cut down this risk.
Laminated arc permanent magnets magnets are strong permanent magnets made of an alloy of samarium and cobalt. They are renowned for their high magnetic strength, exceptional temperature resistance, and reliable performance without oxidation protection. In consequence, they are more suitable for certain applications than Neodymium magnets.
Laminated arc permanent 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.
Technical requirement:
1.The thickness of insulating layers is within 0.04mm.
2. In normal temperature, the bond strength of insulating layers can reach more than 50Mpa.
3. The maximum working temperature can reach 200 ºC.
4. The whole geometric tolerance is within 0.05mm.
5. These small magnets are insulated from each other.
Application scope:
Now aerospace, automotive, motorsport, and industrial markets are turning to laminated rare earth magnets, and are working to balance the tradeoff between power and heat.
Purpose:
To reduce magnetic eddy current loss
