IE3 Series Motors Champion – Premium Efficiency Motors

IE3 series motors are offered from 0.37kW – 375kW in 2, 4 & 6 Pole.

These squirrel cage Induction motors confirming to the IS: 12615 / IEC: 60034-1 are offered in Cast Iron housing with IP 55 protection and with TEFC IC411 cooling as per IS: 6362. The IE3 motors when compared to the non-IE motors offer substantial amounts of savings in energy.

The Champion IE3 Series motors are offered for an Ambient of 50°C, for Altitude < 1000m, with Class F insulation, 63 Series bearing for frame 160 and above with identical bearings at DE and NDE which helps in reducing the inventory. These motors are also provided with Regreasable bearings for frames 160 onwards.


IE3 Premium Efficiency motors from Siemens

Are Siemens motors ready for the changeover to IE3? What are the advantages of IE3? And why is the changeover worthwhile in any case?

Sophisticated technology that pays off

Opting for IE3-compliant asynchronous motors means you can expect total reliability, long life and maximum robustness. And that means your investment is safe. In many cases, too, switching to IE3 will not require any change to the mechanical construction of your machine, because motors from IE1 to IE3 retain the same shaft height. That saves engineering and retrofit costs – and of course using IE3 Premium Efficiency motors from Siemens will make a noticeable saving on your electricity account.

Always the right choice

Premium Efficiency motors from Siemens are available in countless standard versions from 0.37 kW to 1,000 kW – just right for all applications in the manufacturing and processing industry.


Siemens offers three-phase direct on line motors in a range of series up to 1,000 kW.For pumps, ventilators, compressors, in the processing industry or in particularly harsh environments, the range of motors available means the right solution is on hand to meet every requirement.


Innovative rotor technology makes IE3 motors extremely compact. They come with the same shaft height as IE2 motors, which means the mechanical interfaces to the assembly remain unchanged. Because the improved efficiency rating can often be achieved using the same housing, there is no need to change the mechanical structure of the machine in many cases.


Besides lower energy consumption, IE3 Premium Efficiency motors from Siemens offer these winning features:

  • Integrated lifting lugs
  • Easily accessible connection boxes
  • Unchanging shaft heights and the same housing in many cases

IE3 und CO₂-emissions

The IE3 standard represents a contribution to a comprehensive, EU-wide package of measures intended to reduce CO₂ emissions by 20% and increase energy efficiency by 20% between now and 2020.
