A laminated rotor for an electric machine is disclosed. In an embodiment, the rotor comprises a plurality of stacked laminations. Each lamination includes a plurality of radially extending slots arranged about a circumference thereof, and a first chamfer on a surface of each of the slots, wherein the surface mates with a wedge. The first chamfer connects the surface and a first face of the lamination. A stud member passes longitudinally through a hole in the lamination stack, a first end flange member on a first end of the lamination stack, and a second end flange member on a second end of the lamination stack. A first fastener is affixed to a first end of each of the at least one stud member; and a second fastener affixed to a second end of each of the at least one stud member.
