Rotor Magnet N40 Ndfeb Magnet Ring Sintered Permanent Magnet Neodymium
NdFeB is a new type of permanent magnet material, which is an alloy composed of rare earth metal nd fe-b. Among them, nd accounts for 5-15% of the total weight, fe accounts for 1-2%, and the content of b is around 1%.
There are many levels of NdFeB magnets
grade | Max Operating Temperature | grade | Max Operating Temperature |
N30-N54 | 80℃(176℉) | N30UH-N45UH | 180℃(356℉) |
N30M-N52M | 100℃(212℉) | N30EH-N38EH | 200℃(392℉) |
N30H-N52H | 120℃(248℉) | N32AH | 220℃(428℉) |
N30SH-N45SH | 150℃(302℉) |
