本文检测了各向同性粘结Nd-Fe-B磁体开路磁通的可逆和不可逆损失。测量表明,粘结Nd-Fe-B永磁与烧结体具有近似的可逆温度系数,但不可逆损失和长时间时效损失远小于烧结Nd-Fe-B磁体。
The reversible and irreversible losses of open-circuit magnetic flux ofthe plastics binding isotropic Nd-Fe-B magnet were determined. The reversible tem-perature coefficient of the plastics binding Nd-Fe-B permanent magnet was detectedto be similar to that of sintering one, yet the irreversible loss and long-term agingloss of the former are far smaller than the later.
