ABSTRACT:
An axial air-gap rotor includes wound air-core armature coils disposed on one side of a printed wiring board, and a cylindrical commutator disposed at the rotation center. The commutator includes commutator pieces separated from each other by positioning guides provided on the base, and each having a connection terminal integral with and extending axially from an arc-shaped sliding contact portion and flat portion, the printed wiring board further having terminal connection lands for the wound air-core armature coils, and through holes connected to the terminal connection lands in which the distal ends of the connection terminals are fitted and connected on the other side.
