【Abstract】 This paper presents a novel speed detection method suitable for a closed loop variable voltage thyristor controlled induction motor system. The method belongs to the indirect electrical measurement which determines the speed of induction motor by taking the measure of the voltage drop of thyristor. Its theoretical basis and experimental results are given and analyzed.更多还原
