  • Stator supporting structure for rotating electrical machine and rotating electrical machine including the same
    Patent number: 9948159
    Abstract: A rotating electrical machine includes an annular stator, a motor case, and an inner frame. The motor case is disposed radially outward of the stator with a prescribed radial gap. The inner frame fixedly supports one end of the stator in the axial direction of the motor case. The inner frame includes a bolt fastening portion coupled to the one end of the stator without being coupled to the motor case, a bolt fastening portion coupled to the motor case without being coupled to the one end of the stator, and a connecting portion connecting the bolt fastening section and the bolt fastening section. The radial rigidity at the connection section of the inner frame is configured to be lower than the radial rigidity of a bottom section of the motor case.

  • ROTATING ELECTRICAL MACHINE
    Publication number: 20150364966
    Abstract: A rotating electrical machine includes an annular stator, a motor case in which the stator is accommodated, and an annular inner frame with which one axial end of the stator is supported on the motor casing. The inner frame includes a bolt fastening portion, which couples the stator at a radially outer side, and a bolt fastening portion, which couples the motor case at a radially inner side. At a connecting portion between the first coupling portion and the second coupling portion, the radial rigidity is lower than the circumferential rigidity.
