High Efficiency Motors IE3

altaefficienza-cme-motore elettrico ie3

Description

CME high efficiency motors, also called “high performance motors” comply with the efficiency levels established by the new IEC 60034-30 regulation. They are made in appropriately selected materials in order to minimize energy waste and thus increasing the overall efficiency of the motor. 

 They are developed in accordance with energy saving guidelines, so they combine the flexibility of three-phase motors with the use of selected materials in order to reduce energy waste and thus reaching high performances.

Main features:

Available in the versions with 2, 4 and 6 poles for continuous duty S1
Focus on high efficiency 
Since 16th June 2011, in compliance with the IEC 60034-30 regulation, in Europe motors must have a minimum efficiency level corresponding to IE2. The class IE3 (electric motors with an absorption power 7.5 – 375 kW) is compulsory since 1st January 2015. 
Electric motors IE2 are allowed only if equipped with a VSD (inverter), with exception for the smallest motors. For these the regulation will be in force starting from the 1st January 2017. 
The regulation IEC 60034-30 is valid for three-phase asynchronous motors with cage rotor and single-speed between 50 and 60 Hz that: 

  • have a rated power between 0.75 and 375 kW
  • have a nominal voltage up to 1000 V
  • have 2, 4 or 6 poles
  • operate in-line
  • hey are categorized depending on their functions according to IEC 60034-1, part 6.

Included in the regulation are::

  • motors with flange, feet and/or shaft those mechanical dimensions don’t comply with IEC 60072-1

EXCLUDED from the regulation are:

  • with 8 poles
  • developed only to be used with inverters, in compliance with the IEC 60034-25 regulation, completely integrated in other machines, and that can’t be tested separated from the machine.
  • Brake motors
  • Single-phase
  • Double polarity

Typical applications:

High efficiency motors can be used in many applications, for example:

  • renewable energy,
  • textile machinery, packaging and labelling machinery,
  • machine tools,
  • woodworking machinery,
  • machinery for the food industry,
  • conveyor belts,
  • pumps,
  • fans,
  • refrigeration and air conditioning
  • compressors.
