Rare Earth NdFeB and SmCo Laminated Permanent Magnet, High Efficiency Motor Laminated Segmented Magnet, Layered Magnet, Segmentation Technology Lamination Magnet, Neodymium Split Magnet, Permanent Laminated Magnets for high efficiency motors to eddy current reduction
Rare Earth NdFeB and SmCo Laminated Permanent Magnet Item No. MPCO-LAMN OR MPCO-LAMS series
1. Laminated magnetd can reduce eddy current loss in high efficiency motors, high efficiency demands the best material, and the laiminted rare earth are proved to reduce eddy current loss in high efficieny motors , Fewer eddy current loss means lower heat and greater efficiency .
Thinkness avaiable insulating layers less than 20UM ,the maximum working temperature can be up to 200℃ magnet layers from 0.5mm and up ,custom shapes and size in neodymium magent .
3. Application Scope :
Aerospace ,automotive,motorsport and the industrial markets are turning to laminated neodymium magnets, it can be balance the power and heat better than the whole magent .
How to reduce eddy current losses of rare earth 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, such as:
a. Bonded magnet.
b. High-resistivity sintered magnet.
The magnet made by segmentation technology can be called laminated magnet, layered magnet, split magnet and segmented magnet. For magnet segmentation technology, the whole magnet will be segmented into several pieces, then processed into specific shape and dimension after glued together by special isolation glue. High Efficiency Motor Laminated Segmented Magnet
What is the Advantages of Laminated Magnet?
According to many simulation cases and actual products, the magnet segmentation technique has excellent performance to prevent the eddy current. With the increase of segment, the eddy current losses of permanent magnet significantly decreased. Magnet segmentation technique has been already applied in the NdFeB and SmCo magnet.
We can also provide magnetic assembly,even the complete motor robot.
