The motor energy efficiency standards turnover, national standards are not uniform, most of the countries relevant IEC standards, now some of the basics of efficient motor summarized Share:

    1 EFF1 and EFF2 energy efficiency:

    The motor energy efficiency the of EFF1 EFF2 on EU motor energy efficiency rating: In 1999, the EU and the European motor and power electronics manufacturers Association (CEMEP) developed motor energy efficiency standards (EU-the CEMEP protocol). EU-CEMEP the products covered by the agreement is fully enclosed fan cooled (IP54 and IP55) three-phase AC cage induction motor, power range from 1.1 to 90kw, the number of poles 2-pole and 4-pole voltage to 400V, 50Hz, S1 work (continuous rating), standard design (ie the starting performance of the N design the technical requirements in accordance with IEC60034-12), the agreement required for each specification motor high the low two tranches efficiency indicators product efficiency value is lower than the low The indicators called Eff3 motor, between the low index and high index between said Eff2 of motor above the the high targets said Eff1 of motor.

    EFF1 and EFF2 eliminated and the EU energy efficiency trend:

    EU motor eco-design new directive EC No 640/2009 on July 22, 2009 formally introduced, the directive specific implementation is divided into three-step plan, the planned schedule is as follows:

    From June 16, 2011, shall not be less than the level of motor energy efficiency IE2;

  From January 1, 2015, the rated output power of 7.5-375 kW electric motor energy efficiency level shall not be less than IE3, or at least meet the IE2;

    From January 1, 2017, all motor (rated output power of 0.75-375 kW) electric motor efficiency levels shall not be less than IE3, or at least meet the IE2 efficiency level;

    The new standard EN 60034-30:2009 defines the power in the range of 0.75-375 kW low-voltage three-phase asynchronous motor energy efficiency rating, the following specific provisions:

 IE1 = Standard efficiency (similar EFF2)

 IE2 = energy-efficient (similar EFF1)

 IE3 = quality and efficient

    Since June 16, 2010, the motor should be level IE1, IE2, IE3 production and sales. The new energy efficiency rating of the motor must be determined by a new measurement method. The the old European Code EFF2, EFF1 will no longer effective, and will gradually withdraw from the market. Belong to the directive EC No. 640/2009 regulation electrical products exports to the EU market through the EU energy efficiency certification must take pathway.

    Energy efficiency measures in the new method:

EN60034-2-1: 2007 standard revision low voltage three-phase asynchronous motor energy efficiency measurement methods.

The new standards greatly improved the accuracy of the test under specified laboratory conditions. The new standard will replace the old standard EN 60034-2:1996, and has already begun to implement.

Of energy efficiency Instructions:

    State Council [2008] No. 23 issued by the State Council on 1 August, 2008, the notice of the State Council on Further Strengthening the fuel-efficient and energy-saving work.

    China has released energy efficiency standards GB18613-2002, GB18613-2006, GB18613-2012.

GB18613-2002: provides energy efficiency of limited value, evaluating values of energy, power factor.

Range :0.55-315kW.

    Test Method: limit value loss analysis, stray loss of 0.5%; evaluating values of energy measurement method (112B).

GB18613-2006: provides energy efficiency rating, energy efficiency limit, the target limit value of energy efficiency and evaluating values of energy, power factor.

Range: 3,2-level 0.55-315KW; 1 level 3KW-315KW.

Test method: loss analysis, stray loss of 0.5%.

The motor energy efficiency limit of not less than three energy efficiency at rated output power and 75% load efficiency. Target energy efficiency of 100%, 75% load efficiency is not less than 2, the target value of energy efficiency in the commencement of 20110701.

GB18613-2012: provides energy efficiency rating, energy efficiency limit, the target limit value of energy efficiency, energy conservation evaluation values.

Range :0.75-375kW.

    Test method: measuring the input and output power loss analysis.

The motor energy efficiency limit the efficiency of the rated output power of not less than three energy efficiency (2006 version 2, which is equivalent IE2). Target energy efficiency is not less than two (equivalent to IE3), 7.5KW to 375KW target energy efficiency value of the standard implementation of the four years after the entry into force five years after the entry into force of the 7.5KW below the target value of energy efficiency in the implementation of this standard. This standard 20,120,901 effective.
