Laminated rotor machining enhancement

An electric machine comprising:

• a rotor including:
• a lamination stack including a plurality of stacked laminations, wherein 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 plurality of radially extending slots, wherein the surface mates with a wedge, and wherein the first chamfer connects the surface and a first face of the lamination;
• at least one stud member passing longitudinally through at least one 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 affixed to a first end of each of the at least one stud member;
• a second fastener affixed to a second end of each of the at least one stud member;
• the first fastener and the second fastener providing a compression to the laminated stack;
• a plurality of coils positioned within the plurality of slots;
• and
• a stator surrounding the rotor.

A lamination for forming a rotor body comprising:

• a plurality of radially extending slots arranged about a circumference of the lamination;
• a first chamfer on a surface of each of the plurality of radially extending slots, wherein the surface mates with a rotor wedge, and wherein the first chamfer connects the surface and a first face of the lamination;
• and
• at least one hole in the lamination for a stud member to pass through.
