Customzied Specific Requirements OEM or ODM service: Accept Grade: N38AH N38EH N35AH N35EH N35UH N38UH N33AH Surface Treatment: Phosphate / Epoxy Tolerance: +/-0.05mm 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 cut down electromagnetic 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. So the design of laminated magnet can just cut down this risk.
Technical requirements: 1. The thickness of insulating layers is within 0.04mm. 2. The bond strength of insulating layers can reach more than 50MPa. 3. The whole geometric tolerance is within 0.05mm. 4. These small magnets are insulated from each other. 5. The maximum working temperature can reach 200 ℃. 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
Magnetic Segmentation Tech Fan-shaped Laminated Neodymium Magnets
Rectangle Glue Bonding Permanent Laminate Magnet
Glue Block NdFeB Magnets for Reduce Eddy Current
