GE DC Drill Rig Motors User's Manual
GE Transportation
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.
