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.

Rotating electrical machine including a refrigerant passage

Provided is a rotating electric machine, including: a rotary shaft rotatably supported by a front bearing and a rear bearing; a field core firmly fixed to the rotary shaft; and a pulley fitted over the rotary shaft on one end side so as to be rotatable integrally with the rotary shaft. In the rotating electric machine, the pulley, the front bearing, and the field core are arranged in a stated order from the one end side of the rotary shaft toward another end side of the rotary shaft. The pulley is fastened to the rotary shaft with use of a male thread formed on the one end side of the rotary shaft and a nut to be mounted to the male thread. The rotary shaft has a flange portion, which projects radially outward, and is arranged to a position between the front bearing and the field core in an axial direction of the rotary shaft.
