Next Generation Nema Premium® Motors Substantially Lower Operating Costs

There has been a push in the petrochemical industry to higher and higher efficiencies. This can be seen in the revisions to IEEE 841 which is expected to push to NEMA premium as the standard sometime in the near future. Leading motor manufacturers have been motivated by these industry-driven efficiency improvements to investigate the optimization of manufacturing processes and designs to further improve 30 induction motor efficiencies. It´s very important to make it fully understood to the industrial users, how losses are generated and to identify the levers that reduce these significantly, all at an acceptable cost for the investment of the motor. Life cycle costs should also be investigated. This paper will focus on new technologies, design and processes being introduced to improve efficiency of 30 induction motors
