Abstract

See full text

The present invention ensures reliability while reducing the size of an axial air gap rotating electric machine. An axial air gap rotating electric machine has: a stator comprising a plurality of core members arranged in a ring shape, said core members each having an iron core, a coil wound in an iron core outer periphery direction, and a bobbin disposed between the iron core and the coil; and a rotor plane-facing an end surface of the iron core via an air gap in a rotating shaft radial direction. The bobbin has: a tubular portion facing the outer peripheral side surface of the iron core and shorter than the length of the iron core; flange portions extending in the vicinity of both ends of the tubular portion from the outer periphery of the tubular portion toward the vertical direction outside by a predetermined length; and a projection portion being on the outside surface of at least one of the flange portions and near the inner edge of the tubular portion, having an inner peripheral surface facing the end outer peripheral side surface of the inserted iron core, and further projecting in an extending direction of the tubular portion.
