The field weakdc source is used to control the speed by vector control of an induction motor. This field weakening method can separate greatest conceivable torque without suening based vector control of an induction motor has works under six step operations. The rpassing the machine voltage and current evaluations and can use the available dc link voltage completely. The primary intention of the work is to regulate current control regardless of whether the inverter output voltage is saturated i.e. it enters six-step method in mode of operation. Below base speed the drive will work as a typical rotor motion situated vector controlled drive. The inverter switch is controlled by a synchronous PWM system which is dynamic in both linear and over modulation zone. Thus, low switching frequency operation of the inverter is conceivable, for medium voltage application. The proposed induction motor based on six steps for regulating the speed is verified by using MATLAB/ Simulink.
