| Abstract: | Oscillations of current and speed often occur during the soft starting of light loaded induction motor controlled by thyristors.A common simulation model of induction motor was presented and simulated those oscillations during the soft starting.The trigger voltage of induction motor stator and mechanical characteristics of induction motor were investigated.The factors and the cause of oscillation were pointed out.The closed-loop feedback from continued flow angle of thyristor should be introduced in inducti... |
