In this study, speed control of an induction motor by V/f ratio is presented visually in order to figure out the relation between the frequency and the speed of the motor. By the use of the system, transient and steady state behaviours of the motor under different frequencies can be analysed successfully over the visual user interface. The system can be used either educational purposes in engineering courses or industrial purposes in automation systems to determine the best operational parameters of the motor.
