Purpose of motor drive

      Generally in industrial, commercial and utility applications electric motors are used to transform electrical energy into mechanical energy. The motors may be a part of mechanical systems such as mixer, conveyor, pump e.t.c. In many such cases, the speed of the system is determined by its mechanical design and loading. So, it is necessary to control the speed of motor for controlling the speed of system. The speed of motor is mainly controlled by using suitable electronic drive equipment, normally referred as variable speed drives. So the drives are used to

•   Increase the efficiency of a process
•   Provide accurate motor speed
•   Control motor torque
•   Enable the motor to run at a range of speeds
•   Automate and optimize a process                                                                                               

The above listed features help to improve the efficiency and quality of process run by motors.
