Abstract :
Speed changing of induction motors fed from a variable frequency source is studied with a view to minimization of speed transition time. Step as well as linear changes in supply frequency are considered. Expressions for optimum rates of (linear) change of frequency have been obtained analytically and confirmed by model studies. The results apply primarily for large changes in speed.
