ABSTRACT:
A vehicular alternator includes a rotor, a stator and a brush device. The rotor includes a rotor coil wound around pole cores and a pair of collector rings electrically connected with the rotor coil. The stator is disposed around an outer periphery of the rotor across an air gap. The brush device contacts the pair of collector rings and feeds current to the rotor coil. The collector rings are made of dissimilar metal materials respectively. Thus, durability of the vehicular alternator can be improved while inhibiting increase in cost and decrease in output.
