Sintered NdFeB Laminated Permanent Magnets for Motor Technical
requirement:
1.The thickness of insulating layers is within 0.*4mm.
2. In normal temperature, the bond strength of insulating layers
can reach more than *0Mpa.
3. The maximum working temperature can reach **0 ℃.
4. The whole geometric tolerance is within 0.*5mm.
5. These small magnets are insulated from each other.
Glued NdFeB magnets could be glued in any sizes depends on customers requests, there is a max Isolation Resistance requests, glue gap thickness etc, and how to test the isolation resistance as below.
Advantages and Disadvantages of NdFeB Permanent Magnets
1) Is the strongest magnetic of permanent magnets, has the high
energy (BH value) and good coercive force.
2) Manufacturing by the the vacuum sintering process, process
maturity;small dimensions,have the good performances and prices;
energy (BH value) of NdFeB magnets is more than ten times higher
than Ferrites, it is the strongest magnetic materials in the world
today, have magnetic kingreputation.
3) Using the cutting process after sintering,according to the
requirements,by the rapid processing, they can be cutted into
square,disc.,ring,segment(like tile shape),and so on;Dimension
tolerance is commonly +/*0.*5mm,if special request,it can be
controlled within 0.*5mm range by increasing grinding; If
requesting the higher process,using the fast quenching scales
manufacturing Nd-Fe-B binding NdFeB ***8,the repumag of dimensions
can be reached 0.*1mm,but because the organic binder content cause
the low energy product,and the much higher cost of forming
dies.
