Galioto, Steven Joseph; El-Refaie, Ayman Mohamed Fawzi

A stator lamination for an electric machine has a circular lamination with an annular bore therethrough; winding slots therethrough; and, slot closures disposed adjacent to the winding slots. The stator lamination is formed of a dual magnetic phase material, such that the magnetic property of the lamination can have a first state and a magnetic property in a second state, wherein the second state is different than the first state. The slot closures regions are treated so as to transition to the second state. A method of manufacturing an electric machine component is also disclosed.
