Laminated magnets are specialized neodymium-based magnets designed to reduce eddy current losses in high-efficiency applications. These magnets are composed of multiple magnetized layers separated by insulating materials, which help minimize heat generation and enhance performance in high-frequency environments. Common types include Arc Segment Laminated Magnets, Laminated Magnets with Epoxy Coating, Fan Shape Laminated Magnets, and Block Laminated Magnets with Groove.
Function
Laminated magnets function by reducing eddy currents that typically occur in solid neodymium magnets when exposed to rapidly changing magnetic fields. This property enhances efficiency, particularly in high-speed motors, generators, and transformers.
