SEW Explosion Proof Geared Motors

FEATURES

The new regulation 94/9/EG (ATEX100a) contains all requirements for units operated in areas with increased danger of explosion and for the first time includes non-electrical devices in the explosion protection section.
SEW-EURODRIVE develops and produces explosion-proof motors and gear units (in preparation) according to ATEX100a regulation that offer many additional features:

All drives are equipped with the standard enclosure of IP54. The gray cast terminal box has a threading with metric cable screw fitting closing parts meeting ATEX100a.

The gaskets are of improved quality to increase heat resistance; an external protective conductor connection has been installed. Reinforced fan guards and brake sealing rings additionally retained with clamping strips are also standard for SEW.

Vertical drives are equipped with a protective cover and there is a speed or stalling monitoring feature for mechanical variable speed gear units.

SEW-EURODRIVE meets all quality requirements regarding unit safety. Any problems occurring during system operation will be analyzed and considered according to the three unit safety categories.

SEW is offering motors for explosion-proof operating conditions with the following type of explosion protection:

In operating conditions with explosive air-gas-mixtures, the drives are meeting the requirements for type of explosion protection “flameproof enclosure,” “increased safety” or “type of protection n.”

For areas with explosive air-dust mixtures, the standard “Elektrische Betriebsmittel zur Verwendung in Bereichen mit brennbarem Staub” (Electrical devices for the operation in areas with flammable dust) has been met.
