NEMA Premium Update
In the two years since our last EEMODS conference, in response to a need for leadership in the international motor efficiency arena, the National Electrical Manufacturers Association (NEMA) has responded by creating a new NEMA Premium standard for the 50Hz market. This paper will discuss the benefits of global NEMA efficiency standards and how end-users can now specify NEMA Premium motors as components of equipment built for use on their 50Hz grid. The standard builds on the already highly accepted 60Hz standard that was established in 2001. The paper will include performance, test and construction considerations that were necessary to optimize motor features and efficiency in a 50Hz application. This paper will also provide a status of NEMA Premium sales in the previous four years and joint activities with the SEEEM initiative.
