Features
Overview of the advantages of this combination over AC asynchronous motors in protection type
"d" (EN 60079-1; flameproof enclosure):
– High efficiency
– Lighter weight
– Shortest possible delivery times, high availability
– Certified for operation with SEW-EURODRIVE frequency inverters
– Also suitable for pump and fan drives
– Delivery from a single source, from a manufacturer that offers both components itself
– Higher speeds
Strict adherence to guidelines is particularly important in areas with potentially explosive gas/air
and dust/air mixtures. Thanks to many years of experience and competency in this area,
SEW-EURODRIVE ensures that the relevant guidelines are observed. Furthermore, the
company’s expertise is continually being expanded to include new and further developments.
