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.

A method of forming a rotor for an electric machine, the method comprising:
- forming a monolithic rotor body having a central shaft defining an axial direction, a hollow conduit defining a fluid passage with a first portion having a U-shaped bend and a second portion extending axially, a radially-extending post configured to receive a set of windings, and a winding end turn support spaced axially from the post;
- and
- removing a portion of the rotor body by relative rotation of one of the rotor body or a removal tool to the other of the rotor body or the removal tool to define a recess between the winding end turn support and the post.
A rotor body, comprising:
- a post extending in a radial direction and configured to receive a set of electrically-conductive windings about the post;
- a winding end turn support axially spaced from the post by a radially-extending recess;
- and
- at least one conduit within the rotor body defining a fluid passage, the at least one conduit having a U-shaped bend located within the winding end turn support and a second portion at least partially radially underlying the recess.
