摘要：The purpose of the present invention is to achieve a reduction in the size of a control-device-equipped rotating electrical machine. Accordingly, this control-device-equipped rotating electrical machine is provided with: a rotor in which sensor permanent magnets are attached to the rear side of a rotational shaft; a front-side housing having, fixed thereto, a first bearing for supporting the front side of the rotational shaft; a motor frame for accommodating the rotor and a stator; a heat sink having, fixed thereto, a second bearing for supporting the rear side of the rotational shaft; and a control substrate having, mounted thereto, a rotational sensor, a microcomputer, and a drive circuit. The microcomputer controls the drive circuit on the basis of a signal from the rotational sensor, to drive a plurality of switching elements. A smoothing capacitor and/or a noise reduction coil which are connected to the switching elements are/is provided further towards the rear side than the control substrate.
