Considerations for selection and usage of IE3 Premium Efficiency Motors

Motor size
The load factor should be chosen between 65% to 100%, so that the advantage of saving will be achieved. The efficiency under such condition standard motor efficiency curve will be in drooping nature, but energy efficient motors have flat efficiency curve, Hence, fall in efficiency is marginal. Thus energy saving is significant even in partial loads.


Special Application
The benefits of using IE3 motors are maximum in continuous duty applicatiions like blowers, compressors, fans, exhausters & pumps etc.

Assessing coat effectiveness
Saving concluded as follows:
kW = Output of motor
E1 = Efficiency of standard motors
E2 = Efficiency of IE3 motors.

Savings = X x Working Hours x Working Days x Tariff

Method of testing efficiency

The efficiency methhod used to evaluate the efficiency of IE3 motors is more stringent than the method used in case of standard motors.

Opeating speed
IE3 motors have less slip compared to standard motors. Hence, their operating speed is more.

VFD application
When IE3 motors are used for variable loads, the use of VFD results in effective energy saving. Further, the higher inrush current is not encountered by the motor because the VFD modifies the starting current of the motor. It applies low voltage, low frequency supply at the time of starting.

IE3 motors conform to IEC 60034-30:2008 and IS:12615-2011
  • Suitable for continuous process industries where high energy saving is essential
  • Short payback period for replacement
  • Enhanced motor life
  • Less maintenance
Machine tools, textile, air conditioning, dairy equipment, packing machinery, material handling equipment, geared motors, wood processing  plants, solvent extraction plants, edible oil factories, cement plants, petrochemical, pharma and chemical industries.
