GE Products
- A 4-pole rotor starts as a solid, rough forging.
- The shaft, spider and the 4 poles and poletips are created by machining away part of the forging.
- The stripwound field winding is added to complete the rotor

GE offers both induction and synchronous motors for many types of centrifugal compressors. GE’s induction motor line is offered from 1-17,000HP (.75 - 13,000kW) per NEMA or IEC standards as well as API 541 and 547.
GE’s synchronous motor line is available up to 100,000 HP (75,000 kW) per NEMA or IEC standards as well as API 546. For our 4 & 6 pole synchronous machines GE Motors utilizes a solid cylindrical forging. With this design we eliminate the need for bolted pole tips and improve reliability while offering best in class efficiencies.
GE offers a full range of reciprocating compressor motors ranging from 200HP (150kW) up to 27,000HP (20,000kW). With over 75 years of industry experience, we offer both induction or synchronous for these applications. GE Motors can provide shaft extensions for both friction and keyed couplings.
GE offers synchronous generators up to 75 MVA as NEMA or IEC as well as API 546. See figure x below for generator that GE Motors packaged with gearbox and skid for quicker integration for Gas Turbine OEM. |

X$D Ultra 841 |
|
GE’s X$D Ultra7 841 is an ideal choice for any low voltage NEMA motor application. It features 0.04 IPS vibration which is half the IEEE-841 specification. This motor has the highest overall efficiency in the industry and a 2000 volt insulation system which exceeds NEMA MG1 part 31 for motors operating on ASD's. This motor also includes a non-contact laybrinth seal on both the drive and opposite drive ends for added protection against contamination. For increased safety, the motor is manufactured with 4 lifting lugs integrally cast into the frame. All this is backed with a 60/66 month warranty. |
GE Motors has a full line of adjustable speed drives (ASD’s) from small micro sizes up to medium voltage drives 100,000HP (75,000kW). GE also has the ability to package the drives with transformers and powerhouses. Common applications requiring ASD’s are large pumps and compressors using medium or high voltage drives.
As compared to a traditional pipeline compressor mechanical drive, GE Motors offers an electric motor and ASD solution. This will reduce maintenance and operating costs along with greenhouse gas emissions.
Low Voltage Adjustable Speed Drives (ASD’s)
In pipeline pump applications, energy savings and improved flow control can be realized by utilizing a GE electric motor and ASD. GE’s typical drive solution utilizes medium voltage IGBT’s with a 24 pulse converter that exceeds IEEE 519-1992. It also features a heat pipe cooling technology that allows for a more compact design with low noise. It comes with a standard 5 year warranty.
Medium Voltage Adjustable Speed Drives (ASD’s)
Facilities that utilize cooling towers may require low voltage motors for heat exchangers. GE Motors offers an excellent solution for these tough applications: The X$D Ultra7 661. This motor complies with IEEE-841 requirements in addition to roller bearings (for belted loads only). It has a 4-point cast in lifting system for increased safety and IP-55 protection with a 60/66-month warranty. These motors fully comply with API 661 and are specifically designed for heat exchanger applications for the Oil and Gas Industry.
