Design and tests of a 6 MW, 10000 RPM induction motor

The use of high speed electrical motors for direct driving of compressors may be very interesting in terms of installation or maintenance costs and reliability. During the 1980s; ACEC ENERGIE developed the concept of a high speed induction generator driven by two overhung impellers, using the expansion power of natural gas. The same concept of a central motor flanked by two overhung impellers has been used in an induction motor application, for natural gas pipeline compression stations. The authors describe this 6 MW, 10000 RPM application and also show how this high speed electrical motor design may comply with other industrial applications
