Laminated rotor machining enhancement

摘要

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.

主权项

1. A rotor comprising:
a lamination stack including a plurality of stacked laminations, wherein each lamination includes:
a first face; a second, opposing face; and a circumferential surface;a plurality of radially extending slots arranged about a circumference of each of the plurality of laminations, each slot including a radially inward-facing surface configured to mate with a wedge, anda first chamfer on the radially inward-facing surface of each of the plurality of radially extending slots, wherein the first chamfer connects the radially inward-facing surface and the first face of the lamination; a 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 axial end of the stud member; a second fastener affixed to a second axial end of the stud member; the first fastener and the second fastener providing a compression to the laminated stack; and a plurality of coils positioned within the plurality of slots.
