DIN EN 60034-30-1:2014-12

This part of VDE 530 specifies efficiency classes for single-speed electric motors that are rated according to DIN EN 60034-1 (VDE 0530-1) or DIN EN 60079-0 (VDE 0170-1), are rated for operation on a sinusoidal voltage supply and: - have a rated power P_N from 0,12 kW to 1 000 kW; - have a rated voltage U_N above 50 V up to 1 kV; - have 2, 4, 6 or 8 poles; - are capable of continuous operation at their rated power with a temperature rise within the specified insulation temperature class; (Most motors covered by this standard are rated for continuous duty (S1). However, some motors that are rated for other duty cycles are still capable of continuous operation at their rated power and these motors are also covered.) - are marked with any ambient temperature within the range of -20 °C to +60 °C. The rated efficiency and efficiency classes are based on 25 °C ambient temperature according to DIN EN 60034-2-1 (VDE 0530-2-1). Motors rated for temperatures outside the range -20 °C and +60 °C are considered to be of special construction and are consequently excluded from this standard. Smoke extraction motors with a temperature class of up to and including 400 °C are covered by this standard. - are marked with an altitude up to 4 000 m above sea level. The rated efficiency and efficiency class are based on a rating for altitudes up to 1 000 m above sea level. This standard establishes a set of limit efficiency values based on frequency, number of poles and motor power. No distinction is made between motor technologies, supply voltage or motors with increased insulation designed specifically for converter operation even though these motor technologies may not all be capable of reaching the higher efficiency classes. This makes different motor technologies fully comparable with respect to their energy efficiency potential. This edition of DIN EN 60034-30-1 (VDE 0530-30-1) cancels and replaces DIN EN 60034-30 (VED 0530-30):2009-08. It also cancels and replaces Annex A of DIN CLC/TS 60034-31 (VDE V 0530-31):2011-08. In the next revision of IEC 60034-31, this annex will be removed from its contents. The responsible committee is DKE/K 311 "Drehende elektrische Maschinen" ("Rotating electrical machines") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
