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. Laminated Magnet Assembly
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.
Due to the existence of binder, the electrical resistance of the bonded magnet would be 102 to 104 times more than simple sintered magnet, but the motor power and maximum operating temperate will be limited. For sintered magnet, submicron fluoride will be served as additive to enhance the grain boundary electrical resistance. Fluoride will help magnet to form a high resistivity layer on its grain boundary, thus improve the electrical resistivity of the whole material.
The optimal lamination for your application is a balance of the need for the greatest electrical resistance at the operating frequency and the best magnetic performance in the physical envelope of your application. Matching the right Block Type insulation and magnet layer thickness to your application makes all the difference.
