Energy Conservation By Energy Efficient Motor In Industry (Case Study Of Polyplast Industry)
Keywords:energy consumption, energy efficiency, energy saving ,induction motor, energy efficient motor
In the future, crises of the energy will increase due to environmental problem and limited sources. The
electric motors consume a significant amount of electricity in the industrial and in the tertiary sector of the India.
Because of its simplicity and robustness the three phase squirrel cage induction motor is the prime mover of the
modern industry. The electric motor manufacturers are seeking methods for improving the motor efficiencies,
which resulted in a new generation of electric motors that are known as energy efficient motors.
This paper deals with energy conservation by installing energy efficient motor (EEM) instead of standard
efficiency motor. One case study of industry Gopala polyplast limited, Ahmedabad, Gujarat. This transition
becomes a necessity as a direct result of limitation in energy sources and escalating energy prices. In the end of
this analysis there are different practical cases in where EEM is compared with standard motor and rewound
motor, in all these cases energy savings can be achieved and the simple payback is less of five years. The energy
consumption of electric motors is broken into two categories. Direct energy consumption which is the energy
consumed while performing work and indirect consumption the fixed energy consumed regardless of the
operational state. So, it is very interesting the implementation of EEM in the industry.
