Custom HazLoc electric motors for export-focused OEMs



Early May, ELNOR Motors will exhibit on the Offshore Technology Conference (OTC) in Houston, Texas. We will be present together with Protos Inc. to address oil & gas markets. More specifically, we target export-focused OEMs interested in custom HazLoc electric motors. Protos Inc. is our exclusive representative for oil & gas markets in Texas, Oklahoma and Louisiana. OTC 2019 - May 6-9 - ELNOR Motors / Protos Inc. - Booth 4960 Check out our custom HazLoc DC motors, IECEx and ATEX approved!

ELNOR will have a number of custom electric motors on display on OTC:


Custom HazLoc & FHP motors (IECEX, ATEX)


Elnor develops and produces custom-made ‘Exd’ electric motors, which offer the targeted performance and operate reliably in potentially hazardous locations. All motors are built following strict quality procedures in accordance with applicable safety requirements. The explosion-proof motors are certified to ATEX, IECEx and several other standards … and are available as asynchronous single-phase or three-phase motors in 4 frame sizes up to 2.2kW shaft power.



Compact, yet powerful custom-made FHP motors offer a perfect match with applications across industries. Customer-specific integration increases drive robustness and saves on the required space. Experience and accuracy in machine parts production and assembly ensure leading motor specifications, low noise and vibration, and a long lifetime.


Custom-made single-phase motors deliver the required power and low noise & vibration, avoiding all motor oversize disadvantages altogether. The compact motors provide high starting torque (up to 400% rated torque), integrated cooling, customized fixations, etc.


HazLoc motors with integrated speed control IECEX, ATEX


Speed control of HazLoc electric motors is a challenge in ATEX environments. Variable motor speed is achieved using a variable speed drive, which has to be installed in a safe zone. ELNOR Motors succeeded in integrating a variable speed drive into the explosion-proof motor enclosure.



Integrated speed control reduces the overall purchase cost and avoids having a remote speed control installed in a terminal box or outside the ATEX-zone. In addition, the integration eliminates the risk for motor winding damage due to peak voltage because it minimizes the cable distance between the motor and its motor control.


Remote speed control is achieved through a 0-10V voltage signal, a 0-20mA current signal or a turning knob on the motor enclosure.

Typical speed control applications cover electric motors up to 700 Watt in ATEX applications where mixing, dosing or other speed adjustments offer added value.


HazLoc DC motors (IECEX, ATEX)


ELNOR Motors offers custom-designed DC motors with internal brushes, ATEX and IECEx approved.


The development of HazLoc DC motors is complex. In this regard, it is worthwhile considering custom motors. In addition to improving motor dimensions, noise & vibration, drive optimization, multiple mains support, etc., ELNOR is able to resolve other aspects in the process: axle and flange adaptation, motor mounting, highly-durable paint system, etc.



The custom-made DC motors of ELNOR are certified to ATEX, IECEx and several other standards … and are available as brushed DC motor up to 0.75kW.
