DC Drill Rig Motors

GE shipped the first 752 DC motor for a drilling rig in 1955. For more than 55 years, GE has provided dependable 752 DC drilling motors for the toughest drilling applications. GE
is continuing its tradition of providing high-quality, reliable drilling motors for land and offshore drilling rigs worldwide.

Proven performance

No guesswork required. The performance characteristics of GE’s original 752 DC drilling motors have been proven time and time again on all major drill rig operations. The motor performance on GE’s original 752 DC drilling motors has continually met or exceeded customer requirements.

Dependable operation, backed by GE

Thousands of GE’s original 752 DC drilling motors are performing worldwide on all types of drill rigs, providing dependable operations of the rig’s primary equipment. The 752 DC
drilling motors have been reported by rig operators to run for years without service or failure.

Impact design

GE’s original 752 drilling frames and coils are built to last for years. No other manufacturing is licensed by GE. Ask for ORIGINAL GE frames and coils. Do not accept imposters.

GE’s original 752 high torque armature and commutator
were designed exclusively for 752 high torque motors to reduce heat and increase torque. Excessively worn and smaller commutators found on many used armatures can increase maintenance expense by shortening brush life and increasing the risk of flashover.

4340 alloy steel shafts have been provided on all horizontal DC motors since 2002. Today’s demanding applications with high-tension belted loads require strengthened shafts. Beware of used 752 and locomotive armatures equipped with standard carbon steel shafts.
