This document provides an overview of energy efficient motors. It defines an energy efficient motor as one that uses less power to produce the same output as a standard motor. It notes that energy efficient motors have higher efficiencies of 2-6% compared to standard motors due to features like more copper in the windings and reduced fan losses. The document discusses the need for and advantages of energy efficient motors, including energy and cost savings. It also notes some potential disadvantages like higher initial cost and issues with speed control. Applications mentioned include various industrial uses.
Energy efficient motors
- 1. WELCOME
- 2. ENERGY EFFICIENT MOTORS Presented by M.jagadeesh
- 3. CONTENTS What is energy efficient motor(EEM) ? Difference between standard motor and energy efficient motor Need of an energy efficient motors Efficiency Maintenance Applications Advantages and disadvantages Conclusion
- 4. WHAT IS ENERGY EFFICIENT MOTOR? An "energy efficient" motor, simply put, is a motor that gives you the same output strength by consuming lesser amounts of power EXPERIMENTAL RESULTS Type of motor Annual Consumption of energy in kwh Standard motors 870 Energy efficient motors 804.59
- 5. DIFFERENCE BETWEEN STANDARD MOTOR AND ENERGY EFFICIENT MOTOR More copper in the windings. Reduced fan loses. Energy efficient motors operate with efficiencies that are typically 2-6% higher than standard motors.
- 6. NEED: When there is a new installation or modification to your plant. Old motors are damaged and need rewinding. Existing motors are underloaded or overloaded. Protecting other devices.
- 7. EFFICIENCY
- 8. LOSSES : Losses are primarily of two types i.e. core and copper losses. Copper loss Core loss Friction and windage Loss Stray load loss
- 10. SAVINGS
- 11. Cost of energy efficient motors: Usually it is of normal cost and slightly more than the normal motors. It is about 15% to 30% more than the normal motors. In Future, the initial cost may be available at the same cost as a standard motor when the population of EE Motors increases
- 12. ADVANTAGES Operate more satisfactorily under abnormal voltage. Electric power saving. Operating temperature is less. Noise level is lower.
- 14. Disadvantages Portability. Initial cost is more. Speed Control . Applications Motors are suitable for wide industrial applications like paper, cement, textiles, cranes, material handling, machine tools and blowers etc.
- 15. CONCLUSION: Finally i conclude that most of the industrial loads having motors are consuming 70% of the total electricity.so it is better to replace standard motors with energy efficient motors where ever economical. so that we can Save energy. Save money. Save atmosphere from pollution.
