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.
