AC Drilling Motor
1150 HP (858kW)
GE’s AC and DC motors have delivered industry leading
technology for more than 50 years. Pioneering the application
of AC technology to oileld 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 certications: 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 oers 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 oshore applications,
where space is a premium.
