Introduction Introduction Efficiency classification and efficiency determination In the last few years the world-wide development for energy saving motors has led to a multitude of countryrelated regulations, laws and standards. This has made it difficult to compare and evaluate the individual products. To create a uniform world-wide base, the new IEC standard 60034-30 has been issued. This standard replaces the former Voluntary Agreement of CEMEP and at the same time extends the former scope to 2-, 4- and 6-poles and to 0.75 to 375 kW. The marking is done corresponding with the code for type...

At the same time, IE2 motors can also be supplied for use in explosive atmospheres and for incorporation of the most varied mechanical modifications, for example brakes and forced ventilation. (see table “Delivery program IE1, IE2 and IE3”) With the introduction of the minimum efficiency classes IE2 and IE3 the motor specifications of EN 50347 for a correlation between shaft height and foot dimensions can be kept only under certain conditions. Concerning the motor length (dimension L, LC) and the installation size (dimension AC) it can be said that the new IE3 motor design might be significantly...

Introduction Hints about the use of regulation VO(EC) 640/2009 With the regulation (EC) no. 640/2009 of the Commission dated 22nd July 2009 about implementation of the guideline 2005/32/EC the definition of minimum efficiency classes (Minimum Efficiency Performance Requirements Standard MEPS) has been issued based on EN 6003430:2009 for certain types of electric motors and the gradual introduction into the market: Which motors fall within the scope of EN 60034-30:2009? – are designed for duty type S1 (continuous duty) or S3 Single-speed three-phase asynchronous motors with (intermittend periodic...

Availability of IE2 design series complying with foreign regulations: CSA-design, Class 4211-01 (Motors and Generators), File 101691-0-000 This certificate includes the basic series KPR 63…100 / KPER 71…112 – max. 4.8 kW and K10R 132…315 / K11R 132…315 – max. 315 kW (Ex-motors excluded). Based on this certificate a delivery of IE2-motors is possible. The type designation is done with an additional mark after the pole number, ie. K11R 315 M2 IE2. CSA-design, Class 8811-01 (Energy Efficiency Motors), File 101691-0-000 This certificate includes the series WE1R 80…315 EP power range 1…200 Hp, Momentarily...

Introduction Hints for voltage selection according to IEC/EN 60034-30 Rated voltages, rated frequencies and rated output The marking for wide voltage range that is used so far (ie. 380…420 V) must be avoided as the efficiency for both voltages must be stated or the lowest efficiency for the total voltage range. When marking the rated voltage and specification of Zone A oder B acc. to EN 60034-1 only the efficiency class (IE-Code) and the efficiency of this voltage must be stated, for example 400/690 V (Zone B) Δ/Y An alternative possibility is the marking of 400/690 V ± 5 % (Zone A) Δ/Y. This...

Excerpt from VIK-recommendation 1 (Edition: March 2011) Voltage selection according to VIK-recommendation 1, Three-phase asynchronous motor – Techn. requirements …… 4.1.4 Voltage 230 V/400 V* ± 5 %** 400 V/690 V* ± 5 %** 290 V/500 V 50 Hz, Δ/Y 50 Hz, Δ/Y 50 Hz, Δ/Y * Rated voltage acc. to DIN IEC 60038 ** Rated voltage range In an additional tolerance range of ± 5 % the torque must be kept without limitations. For motors with a rated voltage of 290 V/500 V there is no rated voltage range necessary. For Ex-motors with specification of the rated voltage range the motor warming at the tolerance...

Introduction Technical data The performance data can be taken from the motor selection data tables. Further important information for the selection of three-phase asynchronous motors can be found in the main catalogue of VEM “Low voltage asynchronous motors, IEC squirrel-cage motors”. When the application of the motor requires additional regulations, like gas or dust explosion protection, the corresponding motor series must be used. Standards and regulations The motors comply with the relevant standards and regulations, particularly with the following: Titel Rotating electrical machines, rating...
