This paper is intended to provide a novel and simpler way of speed control three phase induction motor using simultaneous The wide range control technique of three speed of induction motor has presented. With this technique the speed control is obtained by changing speed using simultaneous control of frequency and the three voltages which are spaced by 120o with respect to each other at all frequency. The variable frequency drive works principle, it's the electronic controller specifically designed to change the frequency and control signal voltage supplied to the controller and thereby the stator of three phase induction motor.
