ROTATING ELECTRICAL MACHINE

摘要

The purpose of the present invention is to provide a rotating electrical machine such as an electrical motor in which generation of noise can be suppressed. According to the present invention, the motor (a rotating electrical machine) (1) is provided with; an annular stator (2); a motor case (4) in which the stator (2) is accommodated; and an annular inner frame (3) with which one axial end of the stator (2) is supported on the motor casing (4). The inner frame (3) is provided with: a bolt fastening portion (30), i.e. a portion which couples the stator (2) at a radially outer side; and a bolt fastening portion (32), i.e. a portion which couples the motor case (4) at a radially inner side. At a portion between the first coupling portion and the second coupling portion (connecting portion (33)), the radial rigidity is lower than the circumferential rigidity.
