Features
Overview of the advantages of this combination over AC asynchronous motors in protection
type “d” (EN 60079-1; ±ameproof enclosure):
–
High ef²ciency
–
Lighter weight
–
Shortest possible delivery times, high availability
–
Certi²ed for operation with SEW frequency inverters
–
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.
CertiIcations
–
The 4-pole motors from SEW-EURODRIVE are also suited for operation on frequency inverters
according to ATEX, IECEx, and HazLoc-NA
®
–
Category 2 and EPL b and c are certi²ed by prototype testing
–
Motors are certi²ed to HazLoc-NA
®
by CSA
–
In category 3 and division 2, brakemotors are also available
–
The suitability for operation on inverters is con²rmed on the nameplate
