Abstract
A voltage regulator device for a rotary electrical machine, notably an alternator and/or alternator-starter of a motor vehicle. The regulator device (14) comprises one or more electronic components (28) able to contribute to controlling the electric machine, a heat sink (30) having parallel heat-dissipating vanes (32). The heat sink is in a heat-exchange relationship with the component or components, and a support (34) on which the heat sink is positioned. The support is able to be mounted on the electric machine in such a way that the vanes of the heat sink can orient an air flow towards a region of depression provided between the support and the machine. A bearing of an electric machine is equipped with such a device and to an electric machine equipped with such a bearing.
