摘要： An electric machine rotor includes a rotor body configured to rotate about a rotation axis. A winding includes a plurality of end winding portions extending circumferentially over an axial end of the pole core. An anchor is woven into the end winding portions to inhibit movement of the end winding portions relative to the pole core. The anchor includes a first portion extending radially outward along a first row of the end winding portions. A second portion of the anchor extends axially from the first row, beyond a second row of the end winding portions to a third row of the end winding portions. A third portion of the anchor extends radially along the third row. A fourth portion extends axially between two of the end windings in the third row. A fifth portion of the anchor extends radially inward between the second row and the third row.
