| Abstract: | 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. |
