ABSTRACT:
A rotor for an automotive alternator includes a rotary shaft, first and second magnetic pole cores each having a plurality of magnetic pole claws, a bobbin, a field coil, a plurality of permanent magnets, and a positioning mechanism. The magnetic pole claws of the first magnetic pole core are interleaved with those of the second magnetic pole core. The field coil is wound around the first and second magnetic pole cores via the bobbin. The permanent magnets are interposed between the first and second magnetic pole cores. The positioning mechanism, which is made up of at least one of the rotary shaft, the first and second magnetic pole cores, and the bobbin, functions to position the first and second magnetic pole cores in the circumferential direction of the rotary shaft with intervals between adjacent pairs of the magnetic pole claws of the first and second magnetic pole cores being even.
