Abstract
A brush-less rotary electric machine is comprised of a frame having a first and second walls, a stator core fixed to the frame, an armature coil formed of conductor segments, a stationary yoke, a rotary yoke disposed opposite the stationary yoke, first claw pole members disposed opposite the stator core, second claw pole members disposed opposite the stationary yoke, and a field coil fixed to the stationary yoke. The armature coil has radial air passages formed among connection portions of the conductor segments, and the second claw pole members have a fan-shaped projection portion. When the claw pole members rotate, the projection portion supplies cooling air to the radial air passages to cool the second coil end.
