Abstract—This paper presents open loop response of inverter-fed three-phase induction motor drive. The inverter switches are fired by Sinusoidal Pulse Width Modulation Technique (SPWM). The integrated model of inverter-fed induction motor is developed in Matlab/Simulink environment. The open loop response of the dive is analyzed for varying torque conditions. Simulation results of output voltage of inverter, stator current, motor torque and speed of the 3-phase induction motor are analyzed.
