Adjustable Speed drive (ASD) systems are ubiquitous in the electrical industry. Many manufacturers often compete for their share in this ever-increasing market. Lately, customers are becoming savvy and are eager to compare system efficiency and energy usage associated with various motor-drive systems to help them decide on an optimal motor-drive configuration for their applications. The aim of this recommended practice is to provide the industry with a universal method to assess the energy efficiency of motor and drive systems operating at varying load points, including operation beyond base speed and regenerative mode. Auxiliary components, different motor drive configurations, including multi-drive systems fed from a single power source are included in this recommendation. This standard offers an all-encompassing approach to system-wide energy efficiency evaluation. The methodology adopted here is based on energy measurements rather than power to help avoid snapshot results of system efficiency. This Recommendation is prepared by the subcommittee on Standards, under the jurisdiction of the Industrial Drives Committee (IDC) of the IEEE Industry Applications Society (IAS).

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
