High Speed Motor Design For Gas Compressor Applications.
Abstract
Past industrial gas compressor application have utilized existing technology to achieve high rotational shaft speeds. Direct drive high-speed gas turbines or a slow-speed electric motor coupled with a speed increasing gearbox have typically generated the necessary shaft speeds for gas compression. But advances in high-speed motor technology, along with improvements in the cost and performance of variable frequency electronic drives (VFDs), permits an alternative approach. By directly coupling a high-speed motor to a gas compressor, the inherent benefits of such an arrangement can be realized. Primarily, allowing the development of an integrated motor-compressor system can eliminate the need for ancillary support systems, including the gearbox, the lube-oil system, and, in some cases, the dry gas seals. This tutorial is presented to help the gas compression industry better understand motor electrical design, the components that constitute a motor, challenges in taking motors to high speed, and potential application issues. In this way, a less cautious approach may be taken in implementing new technology.
