GE’s AC and DC motors have delivered industry leading 

technology for more than 50 years. Pioneering the application 

of AC technology to oilfield equipment, GE has more than 4,000 

AC units in operation on more than 600 rigs worldwide. 

GE’s AC motors have been field proven in the harshest 

conditions and are now compliant to a broader range of 

industry certifications: ATES, IECEx, and CSAus, satisfying 

the new North American AEx requirements and increasing 

operations across more rigs, geographies and regulated 

territories. GE AC motors, 5GEB20 & 5GEB22, in the 1150hp 

class offers rotor inertia levels that are among the lowest in 

the industry and optimal for drawworks applications. Torque 

& power density levels are also among the highest in the 

industry, optimal for deeper-water offshore applications, where 

space is a premium.
