Abstract

Abstract: The effect of temperature (25 〜200 ℃) on magnetic performance of 33EH sintered NdFeB (/% ：
27. 01 Nd, 64. 75Fe, 0. 35Al, 3. 15Dy, 1. 56Co, 2. 27Cu, 0. 90Ga) including residual magnet and magnet loss etc. has been tested and studied. Test results show that with increasing temperature, the residual magnet decreases linearly, at 100℃; the residual magnet decreases by 7. 6% and at 200 X. the residual magnet decreases by 22%. At 25 - 100 °C with increasing the temperature, the open-circuit magnet decreases by about 1%, at 100 ~ 200℃ with increasing the temperature, the open-circuit magnet loss increases dramatically, at 200 ℃ the open-circuit magnet decreases by 44%. The optimum service temperature of 33EH sintered NdFeB permanent magnets is ≤100 °C.

摘要： 试验研究了温度(25~200℃)对33EH烧结钕铁硼(/%:27.01 Nd,64.75Fe,0.35Al,3.15Dy,1.56Co,2.27Cu,0.90Ga)剩磁、磁感损失等参数的影响。结果表明,随温度升高剩磁呈线性降低,100℃时剩磁下降7.6%,200℃时剩磁下降22%。25~100℃时,随温度升高开路磁感损失约1%,100~200℃,随温度升高,开路磁感损失急剧增加,至200℃时,开路磁感损失达44%,33EH烧结钕铁硼最佳使用温度为≤100℃。
