    Laminated magnet is produced with several pieces of magnets glued so as to reach insulation effect between those pieces. Therefore sometimes laminated magnet is also called insulated magnet or glued magnet. Laminated SmCo or laminated Neodymium rare earth magnets are proven to reduce the eddy current loss for the high efficiency motors.

    1.What the advantage of the laminated magnets ?
    Laminated magnets can reduce eddy current loss in high efficiency motors, high efficiency demands the best material , and the laminated rare earth magnets are proved to reduce eddy current loss in high efficiency motors , Fewer eddy current loss means lower heat and greater efficiency .

    2.Technical requirement
    The thickness available insulating layers less than 20UM ,the maximum working temperature can be up to 200℃ magnet layers from 0.5 mm and up ,custom shapes and size in neodymium magnet .

    3. Application Scope :
    Aerospace , automotive, motor sport and the industrial markets are turning to laminated neodymium magnets , it can be balance the power and heat better than the whole magnet .

    The eddy current loss of rare earth magnet can be reduced by many ways, among them, the material science researchers have proposed to prepare the high-resistivity magnet
    1.Reducing electromagnetic eddy current.
    2.Remaining the same magnetic properties with the whole magnet or even superior.

    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 down lectromagnetic eddy current.

    Smco Magnet are Permanent Magnet that have highest working temperature while have high magnetic properties. Smco magnets are used in aerospace and military areas, storage reserves of samarium mineral are very limited on earth, Since there is no magnet could replace SmCo Magnet, smco magnets are the most expensive magnets.
