ABSTRACT:
The invention involves orienting the metal laminations that form a stator core end in such a way so as to reduce eddy current losses in the finger portions of the metal laminations. The metal laminations are positioned so that the grain orientation is parallel to the magnetic flux lines generated in the finger portions.
