摘要： A rotating electrical machine such that a power supply unit can be efficiently cooled, with no increase in size in an axial direction of the rotating electrical machine, is provided. A rotating electrical machine main body and a power supply unit are integrally fixed, and a refrigerant passage is provided on the rotating electrical machine main body side of a metal frame configuring the power supply unit. The refrigerant passage and a control part that controls power supplied to the rotating electrical machine main body are disposed in the same plane in an axial direction of the rotating electrical machine main body, and the refrigerant passage is disposed farther to a radial direction outer side of the rotating electrical machine main body than the control part.

摘要： A control device-integrated rotary electric machine that has a light weight and a small radial-direction dimension. A cylindrical member is provided between a stator formed by stacking electromagnetic steel sheets and a frame retaining the stator, such that the cylindrical member is in a press-fitted state against the stator and the frame. The cylindrical member has a flange portion at one end thereof, and the flange portion is fixed by being held between the frame and a heat sink which is a member composing a control device.
