Abstract

Embodiments of the present invention include methods and an apparatus to fabricate heat treated laminations (61) such as for high-speed rotors of electrical machines. A method, for example, includes heat treating a steel material, cutting a lamination pattern in the steel material to define a plurality of laminations (61), and bonding sets (31) of the plurality of steel laminations (61).
