ABSTRACT:
A method of manufacturing a rotor for a rotating electrical machine includes the steps of: preparing a first and a second pole core, a rotary shaft, and a field coil; press-fitting the rotary shaft into a through-hole of the first pole core so that the axes of the rotary shaft and the through-hole coincide with each other; mounting the field coil on one of the first and second pole cores; opposing the first and second pole cores to each other so that the axes of the through-holes thereof are in alignment with each other and contact surfaces thereof face each other with a maximum parallelism therebetween; press-fitting the second pole core onto the rotary shaft so that the contact surfaces of the first and second pole cores maximally contact with each other and the axis of the rotary shaft coincides with the axes of the through-holes of the pole cores.
