IEEE 841- 1994 versus IEEE 841 - 2001

IEEE 841 has been widely accepted throughout various process industries as a simple way to specify and purchase a reliable energy-efficient severe-duty motor off the shelf. During the next standard revision cycle, IEEE 841 should be made more user-friendly and provide more consistency between suppliers, as the specification was originally intended. This article will discuss the basic differences between IEEE 841-1994 and IEEE 841-2001 revisions. The features added to the 2001 revision were intended to improve motor reliability and life.
