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
