Induction motors are most commonly used motor in industrial motion control system. Earlier, the nature of industrial purpose of induction motor where off constant speed mechanical drives due to different speed control systems but the recent development in power electronics component have given the way for the development for the power electronics based variable speed induction motor drives replacing DC drives. This paper contains study of the different methodology of induction motor drives. The speed, power & efficiency of induction motor controlled by the process industrial motor drives using a variety of techniques. Among the number of methods of induction motor drive techniques, this paper explain the details about slip power recovery scheme by using multilevel inverters.
