For the majority of the past century, WEG Electric Machinery (WEM) has been manufacturing motors and generators for the petroleum industry. WEM recognizes the uniqueness of each application and collaborates closely with customers to fulfill their requirements.

Motors can be engineered to adhere to API Standards, where applicable, ensuring compliance with welding, structural, vibration, and testing specifications. This approach helps customers minimize costly downtime, ensures the motors start & operate reliably, and features these other advantages from API design:

Stator core laminations are C-5 quality or better to withstand winding burnout if rewinding is required.
Low impedance ground path is welded to the back of the machine's core to divert surges in the power system away from the motor, preventing damage.

Factory balancing provides low vibration for smooth field operation. Dynamic balancing at full operating speed is standard for rotors above 600 rpm. Static balancing is standard for 600 rpm rotors and below.
Starting conditions and capabilities per API requirements.

Motors can be constructed to operate in classified hazardous areas acording to NEC or IEC/EN (ATEX) requirements. For synchronous motors, standard brushless excitation ensures non-sparking performance in hazardous atmospheres.

typical application include:

Centrifugal compressors
Reciprocating compressors
Extruders

Expanders
Pumps
