摘要
研究了超高矫顽力Nd-Fe-B永磁体在不同温度下的磁性能.利用两种不同的计算方法得出了磁体的平均矫顽力温度系数β和平均剩磁温度系数α,并比较了所得的两种不同计算结果.结果表明:超高矫顽力Nd-Fe-B永磁体的磁性能随温度的升高而下降,温度系数变化明显,但其方形度变化不大.
The effects of the temperature on magnetic properties of Nd-Fe-B permanent magnets with ultra-high coercivity was studied. The temperature coefficient β of average coercivity and the temperature coefficient α of the average remanent magnetism were obtained by two different calculating methods. The result shows that with the increase of the temperature the magnetic properties of Nd-Fe-B permanent magnets with ultra-high coercivity is declined, the temperature coefficient of the magnets varies obviously, but the squareness of the magnets is hardly changed.
