Abstract
A method and apparatus for forming a rotor for an electric machine includes serially adding layers of material to form a rotor body having a radially-extending post configured to receive a set of electrically-conductive windings, and also having a radially-extending winding end turn support formed contiguously from the rotor body.
Claims13
A method of forming a rotor for an electric machine, the method comprising:
- serially adding layers of material along a build direction to form a rotor body having a radially-extending post configured to receive a set of electrically-conductive windings, and the rotor body having a radially-extending winding end turn support, and wherein the radially-extending post and the radially-extending winding end turn support are formed contiguous—with the rotor body;
- and
- removing material from the rotor body by relative rotation of one of the rotor body or a removal tool such that a radial segment of the radially-extending winding end turn support is not contiguous with the rotor body.
