Revisions of the periodic conformance testing procedures in the NEMA MW 1000 magnet wire standard

Abstract

In the last few years, there has been a considerable amount of activity generated in the NEMA 6-MW Technical Committee due to a change in philosophy regarding the periodic conformance testing of magnet wire products. In the past, the periodic conformance tests have been designed around the special testing of a few standard AWG sizes, to define the unique properties of a particular magnet wire product type. These periodic conformance tests have been used to describe the uniqueness of the particular insulation system of the MW type, rather than to describe the expected performance of different wire sizes in these periodic conformance tests. The need to perform these periodic conformance tests on other wire sizes has created the demand for a new approach
