ABSTRACT:
An induction motor is driven by a converter which outputs a variable frequency and variable phase A.C. voltage. The frequency is instructed by a signal which corresponds to a difference between a detected speed signal and set speed signal, a signal which corresponds to a difference between a detected magnetic flux intensity signal and set flux signal, and the detected speed signal.
