IE2 SERIES THREE PHASE INDUCTION MOTOR

Since June 16, 2010, the electric motor needs to be produced and sold with IE1, IE2, IE3.The new energy efficiency grade of the motor must be determined by the new measurement method.Motor Efficiency rating IE1 IE2 IE3 EFF1 EFF2 (New Directive EC No. 640/2009).In 1999, the EU and the European Electrical and Power Electronics Manufacturers’ Association (CEMEP) established the Electric motor Energy Efficiency Standards (EU-CEMEP).EU – CEMEP agreement covered by product is fully enclosed type fan cold (IP54 or IP55) three-phase ac squirrel-cage asynchronous motor, power range from 1.1 to 90 kw, the number of 2 and 4 pole, the voltage of 400 v, 50 hz, S1 work week (i.e., continuous rating), standard design (i.e., the starting performance meet IEC60034-12 N design technical requirements), the agreement of each specification motor set high and low two efficiency indicators, product efficiency value is lower than the low index called Eff3 motor, between low and high indicators said Eff2 motor,Eff1 motor with higher index.As is known to all, China is known as the “workshop of the world”, and motor is a bulk commodity in international trade, many international purchasing groups have come to China to purchase motor products.In view of this background, many customers, including those in Europe and the Middle East, have taken the efficiency of electric motors as one of the important indicators when purchasing electric motors, requiring manufacturers to provide proof that their electric motors comply with eu Eff1 or Eff2 efficiency indicators.

Therefore, for three phase electric motor manufacturers aiming at the international market, obtaining the Eff1 and Eff2 efficiency evaluation from authoritative testing institutions in advance will greatly enhance the competitiveness of motor manufacturers in the international market.In order to meet the demａnd of customers at home and abroad for the efficiency evaluation of Effl and Eff2 efficiency motors, the motor testing station can provide customers with the service of testing and evaluating the efficiency of the motors, and issue the recognition certificate to the motor manufacturers who test and evaluate the motors in accordance with the requirements of Eff1 and Eff2 efficiency evaluation rules.The certificate has been approved by customers in European countries and non-American countries.

Features:

(1) High efficiency, IE2 is 3% higher on average than IE1, IE3 is nearly 5% higher on average than IE1.

(2) More high-quality materials should be used.IE2 motor cost 25% ~ 30% higher than IE1, IE3 motor cost 40% ~ 60% higher than IE1.

(3) Because of the low operating temperature, the motor life is longer, which can reduce the maintenance cost.

(4) The starting current is relatively large under typical design conditions.

(5) The rotor inertia is large.

(6) High speed and small slip under rated load.
