There is much discussion in the industry about how to properly electrically test AC stator and wound rotor windings. Topics include test voltage procedure frequency and when to perform the various tests. This article describes how the following standards address these questions NEMA MG 1 2011 MG1 IEEE 43 2000 IEEE 43 IEEE 62.2 2004 IEEE 62.2 IEEE 522 2004
2020 1 15 The stator is mainly designed for handling different frequencies voltages outputs as well as an unstable no. of poles. Construction of Stator. The construction of stator can be done with the laminations of high status alloy steel so that eddy current losses will be reduced. The essential parts in the stator are the outer frame core and winding.
