GE’s AC and DC motors have delivered industry leading
technology for more than 50 years. Pioneering the application
of AC technology to oileld equipment, GE has more than
4,000 AC units in operation on more than 600 rigs worldwide.
GE’s AC motors have been eld proven in the harshest
conditions and are now compliant to a broader range of
industry certications: 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 oers 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 oshore applications,
where space is a premium.
