In one embodiment of the present invention, an electrical machine includes a rotor (10) having a rotor stop (26) axially affixed with respect to a shaft (12) of the rotor (10) . The rotor stop (26) has a surface (28) which is machined after assembly of the rotor. The rotor is then assembled into the electrical machine, with the machined rotor stop surface (28) accurately locating the rotor (10) axially within the electrical machine. The rotor stop surface (20') includes at least one groove (30) to prevent the formation of long, continuous machining chips during the machining operation. |
