In the rotating electric machine, the pulley, the front bearing, and the field core are arranged in a stated order from the one end side of the rotary shaft toward another end side of the rotary shaft. The pulley is fastened to the rotary shaft with use of a male thread formed on the one end side of the rotary shaft and a nut to be mounted to the male thread. The rotary shaft has a flange portion, which projects radially outward, and is arranged to a position between the front bearing and the field core in an axial direction of the rotary shaft.

Each of the plurality of claw pole segments includes a radial projecting member, an axial outer surface extending to a cantilevered end portion, and an axial inner surface extending axially outwardly of the radial projecting member to a cantilevered end section. A first side surface extends between the axial outer surface and the axial inner surface from the radial projecting member to the cantilevered end portion and the cantilevered end section, and a second side surface extends between the axial outer surface and the axial inner surface from the radial projecting member to the cantilevered end portion and the cantilevered end section. The first and second side surfaces define a taper of the claw pole segment. Each of the first and second side surfaces includes a recessed portion that extends into the claw pole segment.

A generator system may include a belt configured to support a transportation load. The belt may be located between a first road segment and a second road segment of a road, wherein movement of the belt may generate motive power. The generator system may also include a generator operatively connected to the belt and configured to convert at least a portion of the motive power into electric energy.
