            Procedure

           An AC drive is a device used to control the speed of an electrical motor in order to: enhance process control.
           reduce energy usage and generate energy efficiently. decrease mechanical stress on motor control applications.
           Optimize the operation of various applications relying on electric motors.
           1  AC drives are used to steeples speed control of squirrel cage induction motors mostly used in process plants
              due to its ruggedness and maintenance free long life.
           2  AC drive control speed of ac motor by varying output voltage and frequency through sophisticated
              microprocessor controlled electronics device.
           3  AC drive consists of Rectifier and inverter units. Rectifier converts AC in DC voltage and inverter converts DC
              voltage back in AC voltage.
