Explosion-Proof AC Motors


EDR.. explosion-proof motors bring safety and performance to your system: whether according to ATEX, IECEx or HazLoc-NA®. The EDR.. motor series features 13 sizes and can be used in environments with explosive air/gas mixtures and/or air/dust mixtures.


You can rely on their drive technology, even in potentially explosive atmospheres. There is no need to make any compromises either in terms of safety for your application or in terms of the variety of performance levels of the drives used.


This is because the explosion-proof AC motors from the EDR.. series comply with the most important international standards and directives.


They meet all requirements for tools and fixtures intended for use in potentially explosive atmospheres as defined in EU Directive 94/9/EC (ATEX), or as of April 20, 2016 of the EU Directive 2014/34/EU (ATEX). They are also available with different protection types or IP degrees of protection depending on the atmosphere, i.e. gas or dust. In terms of their safety requirements, motors from the EDR.. series comply with equipment group II. In simple terms: You can use these explosion-proof motors in categories 2 and 3, in gas zones 1 and 2, and in dust zones 21 and 22.


Directive 2014/34/EC has been applicable since February 26, 2014 for devices and protective systems for designated use in potentially explosive atmospheres. This directive replaced directive 94/9/EG.


The motors are available with IECEx certification according to EPL b and c (Equipment Protection Level) for countries that recognize IECEx regulations.

HazLoc-NA® motors comply with the Class Division System and are certified by CSA for use in Division 2 Class I (gas) and Class II (dust).


The motors come in 14 sizes from 63 to 315 which cover a power range from 0.12 kW up to 175 kW (50 Hz) or 200 kW (60 Hz), ensuring varied levels of performance. This thus enables you to avail of countless drive combinations for the most diverse systems and machines in potentially explosive atmospheres.
