A stator for a rotating electrical machine, the stator including a tubular core having a plurality of slots; and a coil mounted in the core, wherein the coil includes a plurality of conductor wires aligned in the slots, each of the conductor wires has ends projecting beyond the slot, a pair of the ends are bonded together to form a bonded end, a plurality of the bonded ends are arranged next to each other in a circumferential direction of the core and are arranged in a radial pattern so as to extend in a radial direction of the core, and a cap is formed by molding using a resin material having electrical insulation properties so that the cap integrally covers adjacent ones of the plurality of bonded ends.

Stator for rotating electrical machine

In a rotor for the dynamo, the interior circumference face of a rotor core main body makes contact in a thermally transmissible manner with a rotor axle, and the rotor axle includes a cooling medium circulation space. The rotor is provided with a cooling medium supply member, which supplies the cooling medium to the cooling medium circulation space. The cooling medium supply member is provided with a cooling medium supply path that extends in the rotor axle direction, and cooling medium supply holes that extend externally in the direction of the rotor diameter. The cooling medium supply holes are provided with supply apertures that open toward the cooling interior circumference face. The rotor axle is provided with cooling medium discharge holes that extend externally in the direction of the rotor diameter. The cooling medium discharge holes are provided with discharge apertures that open externally in the diameter direction.
