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

Block 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.

Aerospace and Automotive: Used in aerospace and automotive applications requiring high-performance and reliable magnetic components.

Laminated Magnets-The right way for solving eddy effect
Laminated magnets are a type of magnets designed to reduce energy losses and improve efficiency in electrical devices. They are essentially magnets made by stacking thin layers, or lamination, of magnetic material together. Each layer is typically coated with an insulating material to prevent electrical currents from flowing between them. N38 Block Laminated Magnet with Groove and Epoxy

The primary advantage of laminating magnets is to minimize eddy current losses. Eddy currents are loops of electrical current that can form within conductors when they are exposed to a changing magnetic field. These currents generate heat and waste energy. By laminating the magnetic material, the eddy currents are confined to each thin layer, and the insulating coatings prevent them from flowing between layers. This results in a more efficient magnetic field with less energy lost as heat.  Block Neodymium Iron Boron Laminated Magnet with Groove

Laminated magnets are commonly used in applications where magnetic fields are rapidly changing, such as in electric motors, transformers, and generators. They help enhance the performance and longevity of these devices by improving energy efficiency and reducing heat generation.

What is the glue thickness of the laminated magnet？ N40H Neodymium Laminated Block Magnet Rectangle 20x20x5mm
The glue thickness in a laminated magnet can vary depending on the specific application and design requirements. In general, for laminated magnets, the adhesive layer between the lamination is typically very thin, often in the range of 0.1 to 0.3 millimeters (0.004 to 0.012 inches).

The primary goal is to ensure a strong bond while minimizing the impact on the magnetic properties of the laminate. Thin adhesive layers help maintain the overall performance of the magnet while providing the necessary structural integrity.  NdFeB N42H Rectangular Sqaure Block Laminated Magnets 30x30x5mm
