Frequently Asked Questions About laminated magnets
What are laminated magnets?
Laminated magnets are permanent magnets made by bonding multiple thin magnetic layers with electrically insulating adhesive. This structure significantly reduces eddy current losses in high-speed rotating equipment while maintaining strong magnetic performance.
Why are laminated magnets used in electric motors?
Laminated magnets help reduce heat generation caused by eddy currents during high-speed operation. They improve motor efficiency, increase power density, and extend the service life of the motor.
What applications are laminated NdFeB magnets suitable for？
Laminated NdFeB magnets are widely used in electric vehicle traction motors, servo motors, aerospace motors, industrial automation equipment, wind power generators, and other high-speed motor systems.
What magnet grades are available？
We offer laminated magnets in a wide range of NdFeB grades, including N35–N52, as well as M, H, SH, UH, and EH grades for different operating temperature requirements.
Can you manufacture custom laminated magnets？
Yes. We provide OEM and ODM services for custom laminated magnets, including arc, block, segment, ring, and other special shapes based on customer drawings or technical specifications.
