Low Eddy Current Losses Segmented Lamination Magnet Item No. MPCO-LAMN series
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.
Lamination magnet: reduce the eddy current loss of the motors(decrease the heat and enhance the motor efficiency).We can help you relize the magnet customizationof the following contents:
(1)Insulation thuckness: 5um-100mm
(2)Insulation layers: 2-40 layer
(3)Max working temp. of the magnet: 60-400 degree
(4)Temp. Resistance of the magnet surface coating: 200-500 degree
(5)Corrosion resistance of the magnet surface coating: Neutral salt spray resistance can be over 1000 hours and PCT can be over 500 hours.
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.
Magnet segmentation technology is a very practical way to make high-resistivity magnet without changing the composition of the magnet.
