High-Speed Electric Drives: Technology and Opportunity

Abstract

This article provides background on the development and installation of high-speed electric motors (induction and synchronous) and controllers. There are compelling reasons for electric drives to be considered for applications that would conventionally be driven by steam turbines, gas turbines, and engines or motors with speed-increasing gearboxes. Electric drives offer an opportunity for efficient use of natural resources, clean and (comparatively) quiet power conversion, improved process control, and very attractive life-cycle cost. High-speed electric drives utilize technology (including variable speed control) to meet the needs of a rapidly changing industrial world. The high-speed electric drive provides another valuable option for consideration by the gas pipeline owner. This option needs to be considered as part of initial strategic planning. The electric option offers many "system" benefits for pipeline owners. It represents proven technology, and significant potential opportunity.
