Sintered ndfeb magnets is the highest temperature can be used?
_ ndfeb strong magnet manufacturers
Can use what is the highest temperature of sintered ndfeb magnet?
Magnet highest use temperature depends on the magnetic magnet itself and the selection of working point.
Magnets are working point can be represented the permeability coefficient of magnets.
For the same magnets, magnetic circuit of the higher the permeability coefficient (
The more the magnetic circuit closed)
, the highest use temperature of the magnet is high, the performance of the magnet is stable.
So the highest use temperature of the magnet is not a definite value, but changes with the close degree of magnetic circuit.
Under the premise of sintered ndfeb in a given working point, the brand of the highest temperature is as follows: brand N M
EH highest working temperature ℃ & ensp;
200 if the actual working temperature close to the highest temperature, appeared significantly and magnet demagnetization, at this point either must improve magnetic circuit, in order to improve the permeability of magnetic circuit;
Must choose either higher grades the performance of the class, so as to guarantee the normal work of the magnet.
