摘要

根据钕铁硼烧结磁体的温升速率估算了钕铁硼烧结磁体的涡流损耗。得到的涡流损耗值与积分元法的模拟数据吻合。结果表明，分磁铁的方法能有效地抑制电流损耗。此外，还观察到交流电的高次谐波效应是各次谐波的简单相加。

Simulations and experiments on eddy current in Nd-Fe-B magnets

The eddy current loss of a Nd-Fe-B sintered magnet is estimated from temperature rise rate of their magnets. The obtained values of the eddy current loss coincide with the simulated data of the Integral Element Method. The method of dividing magnet is found effective in the suppression of the current loss. Also, it is observed that the higher harmonic effects on the alternating current are simple addition of each harmonics.
