ROTATING ELECTRICAL MACHINE

摘要

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.

1. A rotating electrical machine, comprising:
an annular stator; a motor case disposed radially outward of the stator with a predetermined gap; and a support member that fixedly supports one end in an axial direction of the stator with respect to the motor case, the support member including
a first coupling portion coupled to the one end of the stator away from to the motor case,a second coupling portion coupled to the motor case away from the one end of the stator, anda connecting portion connecting the first coupling portion and the second coupling portion, the radial rigidity at the connecting portion of the support member being configured to be lower than the radial rigidity of a portion of the motor case for supporting the stator via the support member, and the second coupling portion being disposed radially inward of the stator.
