Abstract

Method for making an electrical machine (10), especially a three-phase generator for vehicles, that comprises a stator (16) and a rotor (20). The rotor (20) comprises a first and a second claw pole (22, 23) from which claw pole fingers (24) respectively extend in the axial direction from claw pole roots (60). A centering point (74) for a tool is located on a rear radius (72) of the claw pole roots (60).
