Laminated Magnet is a specialized type of magnet designed to optimize performance in applications requiring high efficiency and reduced energy losses.

Laminated Magnet is essential for reducing eddy current losses in high-efficiency motors. The demand for high efficiency necessitates the use of top-tier materials, and laminated rare-earth magnets have consistently proven their ability to minimize these losses. By decreasing eddy current losses, these magnets reduce heat generation and enhance overall efficiency.

Applications
Electric Motors: Commonly used in brushless DC motors, synchronous motors, and other types of electric motors where high efficiency and performance are required.
Generators: Used in generators to enhance performance by reducing losses due to eddy currents.
Transformers: Utilized in transformers to improve efficiency and reduce heat generation.
Electromagnetic Devices: Applied in various electromagnetic devices where high magnetic performance and reduced energy losses are essential.
Aerospace and Automotive: Used in aerospace and automotive applications requiring high-performance and reliable magnetic components. Neodymium Segmented Magnet

Laminated magnets can reduce eddy current Loss in high efficiency motors. Gluing and Fabrication NdFeB Segmented Laminated Block Magnets

High efficiency demands the best material, 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 samll magnets are insulated form each other and can down lectromagnetic eddy current. Neodymium Segmented Magnet Reduce Eddy Current Loss for High-efficiency Motors

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. Neodymium Segment Lamination Magnet In Aerospace and Automotive
