With the explosion-protected EDR.. motors, we bring safety and performance to your system – whether the drives are used by you or your customers in Europe, North America or other countries. Motors from the EDRN.. series are available in 28 sizes and can be used in environments with explosive air-gas mixtures and/or air-dust-mixtures.
No compromises in hazard zones: high-performance, explosion protection-compliant motors

You can rely on our 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 our explosion-proof AC motors from the EDR.. series comply with the most important international standards and directives.
The following rule sets were applied to enable use in as many countries as possible:
- ATEX: EU Europe and countries that recognize ATEX.
- IECEx: Countries that recognize IECEx.
- HazLoc-NA®: USA and Canada.
In Europe, the 2014/34/EU (ATEX) directive applies to devices and protection systems designated for use in potentially explosive atmospheres. EDRN.. motors meet all defined requirements for equipment intended for use in potentially explosive atmospheres as stipulated in the directive. 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, the motors of the EDRN.. series comply with equipment group II. To put it simply, you can use these explosion-protected motors in categories 2 and 3, in gas zones 1 and 2, and in dust zones 21 and 22.
For countries that recognize the IECEx system, the motors are available with IECEx certification in the EPLs b and c (EPL = Equipment Protection Level).
Based on the approvals to ATEX or IECEx, there are country-specific approvals for China (CCCEx), Korea (KCs), the Eurasian Customs Union (EAC Ex), Ukraine (UA TR) and Brazil (INMETRO).
The HazLoc-NA® motors have been certified by the notified body of the CSA Group under the Class Division System for use in class I (gas) division 2 and class II (dust) division 2. They meet the requirements of the Canadian C22.1 and US-American NFPA70 codes.
The motors come in 28 sizes (from 63 to 315), covering a power range from 0.12 kW to 200 kW. We thus provide you with access to countless drive combinations for the most diverse systems and machines in potentially explosive atmospheres.
Only half the solution without a gear unit? Then use our and combine an explosion-protected motor with a helical, parallel shaft, worm, bevel gear or SPIROPLAN® gear unit of your choice. The range also includes a suitable planetary gear unit or helical-bevel gear unit for servo applications.
