Ignition protected motors from WINKELMANN

These direct current motors with explosion protection in a flameproof enclosure (ignition protection class "d") are approved in accordance with Directive 94/9/EC for areas with an explosive atmosphere.

This product line can be used in Zone 1 and Zone 2 of equipment category 2G respectively in Zone 2 of equipment category 3G.

The motor is cooled via the surface with an axial fan – i.e. dependent upon the motor speed (IC 411) or independent of the motor speed (IC 416). Uncooled motors with cooling type IC 410 are also possible.

Direct current explosion-proof motors in flameproof enclosure with cQPSus Certificate

In cooperation with the Canadian certification body QPS Evaluation Services Inc. and the DEKRA-NL in Arnheim, we got the motor series of size 9-22 certified.

Our motors comply with the recognized safety regulations according to the following standards:

  • CSA C22.2 No. 100-14,
  • CSA C22.2 60079-0:2015 6th,
  • CSA C 22.2 60079-1:2011 6th,

  • ANSI/UL 60079-1:2009 6th und
  • UL 1004-1 2nd ed.

The motors can be used in the following areas:

  • Ex db IIC T4 Gb
  • Class 1 Zone 1 AEX db IIc T4 Gb
  • Class 1 DIV. 2 Group ABCD T4
  • For an ambient temperature range of -55°C to +40°C.

Motors according to IECEx

For a globalised market, Standards with a worldwide validity an accordingly authorised products are essential. To also fulfil the requirements of the international Standards acc. to IEC (International Electric Commission), WINKELMANN has now achieved the IECEx certification for the DC motor series in flameproof enclosure. The basics for this new certifications is the ATEX motors product series which is identical in construction.

Worldwide customers and users can thus chose between IECEx or ATEX certified motors without restrictions.
