Long Term Stability for NdFeB Magnets

在现代化电机设备设计中，人们为什么选择烧结钕铁硼？有一个极其重要的因素就是钕铁硼永久磁铁在应用过程中性能的长期稳定性。
永磁钕铁硼的稳定性，分别是指温度稳定性和磁力稳定性。温度稳定性是指永磁体由所处环境温度的改变而引起磁性能变化的程度。磁稳定性是表示在施加外加磁场条件下，引起磁性能发生变化的程度。永磁电机设备在运行时，由于电机温升的影响以及电枢绕组的存在，永磁电机内永磁钕铁硼材料的性能由温度和磁场两个因素共同影响。

In electrical machine design，why the experts choose NdFeB Magnets ?
An important aspect that long term stable polarization performance of permanent magnets over the lifetime of the application.

The stability of Permanent NdFeB magnet,they are temperature stability, and magnetic performance stability. Temperature stability of the permanent magnet by means of temperature change in the environment can cause changes in the degree of magnetic properties. Stability of the magnetic field is applied under the conditions applied, the extent of causing magnetic change. When the permanent magnet motor system works, due to the presence and influence of the motor armature winding temperature rise. In motor ,the performance of permanent NdFeB magnets,which effected by the temperature and magnetic field.
