The Engines and transmissions from SEW-Eurodrive meet the requirements for equipment for use in potentially explosive atmospheres according to Atex (Europe), IECEx (International) and Hazloc-NA (North America). The certification according to these standards predestines them for worldwide use.
The motors and geared motors are offered in IECEx according to Equipment Protection Level (EPL) Gb and Gc (gas protection) as well as Db and Dc (dust protection) and as Atex-compliant drive in the categories 2G, 2GD and 3GD, 3D for the zones 1 / 21 and 2 / 22. In the category 3GD and 3D they are also available as brake motor. The combined gas / dust approvals of the geared motors simplify the selection of the respective drive components, reduce the variety of variants and enable the use in combined gas / dust zones.
The 4 2 and 3 (or EPL .b and .c) XNUMX pole motors are suitable for operation on the frequency converter, even in field weakening mode. The motors and converters are available as electrical equipment in the types of protection "e" (increased safety), "nA" (non-sparking) and "tb" and "tc" (dust explosion protection). The gearboxes as non-electrical equipment are certified in types of protection "c" (structural safety) and "k" (fluid encapsulation).
The compact and performance-oriented properties of the standard drives are also reflected in the explosion-proof motors, which are available in different versions in the power range between 0,12 and 75 kW.
