This paper presents scalar & vector control of three phase induction motor. Scalar control as the
name indicates is due to magnitude variation of control variable only disregards any coupling
effect in the machine. The scalar control is very simple method for controlling the speed of
induction motor compared to the vector control which is more complex. Vector control is
completely mathematical equations based model on control of torque and speed of a three-phase
indirect vector controlled VSI fed cage induction motor drive that is controlled through the pulse
width modulation. Finally comprise the result of scalar and vector control techniqu
