Abstract:
A rotary electric machine, comprising:a frame having an air opening through which air flows; a stator core disposed to be supported in the frame, the stator core having a plurality of slots; a stator winding including a plurality of conductor segments each of which is formed into an approximate U-shape having a part of leg parts, the stator winding being inserted into the stator core through the slots to have both coil ends protruding from both ends of the stator core, respectively; a rotor disposed opposite to the stator core to be rotatable; a cooling fan for blowing air toward the both coil ends of the stator winding; and an elastic member disposed between the stator core and the frame to be inserted therebetween, wherein: the conductor segments are inserted into the slots of the stator core in such a manner that, the leg parts of each conductor segment penetrate through the slots from one end of the stator core to the other end thereof, and are connected at top ends; and the frame includes first and second frame parts separated in an axial direction of the rotor, the first and second frame parts being disposed to be fastened in the axial direction while press-contacting outer peripheral edge parts of the stator core through the elastic member.
