Abstract :
In this paper, the author has aimed at the variable-voltage controlled induction motor, analyzed the steady-state performance of variable-voltage thyristor controlled induction motor system, and presented the mathematic model and circuit model of such system. Power factor, as a significant variable to measure the efficiency of motor operation, is particularly studied in the paper, and the control strategy based on the studies of power factor and slip is given. The simulation curves and real waves are shown in the result. Finally, the transient performance of induction motor is mentioned. The analysis and results reveal that such system based on the special arithmetic is available.
