ROTATING ELECTRICAL MACHINE

摘要

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.

1. A rotating electrical machine, comprising:
an annular stator; a motor case configured to accommodate the stator; and an annular support member configured to support one axial end of the stator on the motor case, wherein the support member includes
a first coupling portion forming a coupling portion with the stator on a radially outer side; anda second coupling portion forming a coupling portion with the motor case on the radially inner side, at a portion between the first coupling portion and the second coupling portion, the radial rigidity being lower than the circumferential rigidity.
