Abstract

Embodiments of the present invention provide methods and insulated laminate cores to be used in electric machines (201). A laminated core (203, 211), for example, includes a plurality of electrical steel laminations (205) defining a lamination stack having a core length and one or more insulating laminates interspersed along the core length to thereby reduce stack length and reduce eddy current.
