WEG / EM has manufactured motors and generators for the petroleum industry for over 100 years.
We understand that every application is different and will work with the customer to meet their needs.
Motors can be designed to API Standards (where applicable), meeting welding, structural, vibration
and testing requirements. Motors can be built for operation in classified hazardous areas per NEC or
IEC/EN (ATEX) requirements. For synchronous motors, standard brushless excitation is non-sparking
for hazardous atmospheres

Ex nA motors do not require certification by any
third party entity (a manufacturer’s compliance
declaration is sufficient). Nevertheless the
Ex nA motors manufactured by WEG are
certificated by Ex NB BASEEFA.
