摘要
依据异步电机T-I型等值电路的向量图,提出了一种实时检测异步机转子时间常数T2的方法。并对实时检测的基本原理作了详细论述。这种检测方法不仅考虑了电机温度对转子电阻的影响.而且考虑了磁路饱和对转子电机的影响。文章最后给出了实验结果。
This paper proposes a novel method of detecting the rotor time constant T2 of a motor on line in terms of the vector diagram of T-I type equivalent. The principle of detecting T2 is described in details, in which not only the effect of rotor resistance r2 varying with temperature, but the influence of rotor reactance L2 changing with core saturation are involved. Some experimental results are shown in the paper as well.
