Speed Control Of Induction Motor Using Variable Speed Drive

Abstract

Industrial applications require variable speed motors , Squirrel cage induction motors are simpler in structure than DC motors. They are robust and reliable. They require little maintenance and are available at very competitive prices. They can be designed with totally enclosed motors to operate in dirty and explosive environments. Their initial cost is substantially less than that of commutator motors and their efficiency is comparable. All these features make them attractive for use in industrial drives.To control the speed of induction motor variable speed drive is the best choice. because of it’s great advantages. Variable speed drive simulated and analyzed with matlab -simulink .and from the simulation results it showed that variable frequency drive is the best solution for fixing inherent motor issues and energy saving can be best tackled by this drive
