  • Patent number: 12301075
    Abstract: The reliability of a rotating electrical machine is improved. A method for manufacturing a stator used in a rotating electrical machine includes: a first step of arranging a first segment coil and a second segment coil to face each other; a second step of processing the first segment coil to generate a bridge part that comes into contact with the second segment coil; and a third step of joining the bridge part and the second segment coil by laser welding.

  • Patent number: 12218570
    Abstract: A rotating electric machine including a rotor, a stator, and a case forming outflow holes through which a refrigerant flows out toward an extra-slot conductor of a stator coil. The outflow holes are arranged above the extra-slot conductor, and when the bending direction of the extra-slot conductor with respect to an intra-slot conductor arranged on the outermost diameter side in a slot in the stator coil on an upper portion of the stator is a coil bending direction, the first outflow hole is arranged on the bending direction side with respect to a vertical line passing through the rotation center axis, and the second outflow hole is arranged on a side opposite to the bending direction with respect to the vertical line, and the arrangement angle of the second outflow hole with reference to the vertical line is larger than the arrangement angle of the first outflow hole with reference to the vertical line.

  • Publication number: 20230268783
    Abstract: Provided is a stator core of a rotating electrical machine in which a core back and teeth are formed by laminating a plurality of thin steel plates with an adhesive interposed therebetween. The stator core includes a first stator core that is formed by applying the adhesive to a first region covering the core back and the teeth between the plurality of thin steel plates, and a second stator core that is formed by applying the adhesive to a second region, which has an area smaller than an area of the first region, between the plurality of thin steel plates. The first stator core is disposed at least at one end of the stator core in a laminating direction of the thin steel plates.
