Motor segment NdFeB magnet
The neodymium magnet is third Generation of Rare Earth magnets. It is the strongest magnet in World at present. It is mainly applied to loudspeaker, speaker parts, holding tool, motor and so on.
it is the most powerful and advanced commercialized permanent magnets today.
Characteristic of Sintered NdFeB:
1. Neodymium magnets are hard, brittle and easily corrode.
2. Neodymium magnets lose -0.09 ~ -0.13% of Br/ ° C. They areworking stability under 80 ° C for low Hci and can reach 200 ° Chighest working temperature for high Hci.
3. Excellent strength value . The highest (BH)max reaches up to 52MGOe .
4. Strip casting and HDDR technology allows us to make high performance NdFeB over N52 possible.
5. Surface treatments have been developed that allow them tobe used in most applications. The treatments include gold, nickel, zincand tin plating and epoxy resin coating.
Neodymium Iron Boron (NdFeB) magnets, the most powerful permanent magnets available today, possess high energy up to 52MGOe and wonderfulcoercive force. As the third generation of Rare Earth magnets, NdFeB magnets are less brittle than SmCo, and the cost is much more resonable
