Speed Control of Three Phase Induction Motor by using V/f Method

Abstract

The electric drives system used in industrial applications are increasingly required to meet the higher performance and reliability requirement. Today about 90% of all industrial motor applications use three phase induction motor because they are simple in design, easy to maintain, and are less costly than other designs. This depends upon the batching system which is one applications of weaving machine which rolls the cloth with specific tension so that it should neither slacken the cloth nor tightened in by replacing DC system with the AC system. The motion of this loom is controlled by induction motor where in the AC drive is used to run the induction motor which rotates the drum through pulleys.
