Firstly, the reasons of DC magnetic bias on transformer are studied.
首先，本文介绍了产生变压器直流偏磁的原因。
Researches indicate that negative peak value of the output voltage of the testing winding is linear with the positive DC magnetic biasing potential;
研究得出，当磁芯中存在正偏磁时，检测绕组输出端电压的负峰值与直流偏磁磁势是线性关系；
Since HSY requires dc magnetic field, an exciter with control circuitry is needed in addition to the conventional PMSY drive unit when employed as a motor.
HSY作为电动机使用时，由于需要直流磁场，与普通pmsy的驱动单元相比，应额外增加一个励磁电路。
