A voltage regulator device for a rotary electrical machine, notably an alternator and/or alternator-starter of a motor vehicle. The regulator device () comprises one or more electronic components () able to contribute to controlling the electric machine, a heat sink () having parallel heat-dissipating vanes (). The heat sink is in a heat-exchange relationship with the component or components, and a support () 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.

A voltage regulator device provided in a bearing of a rotary electric machine of a motor vehicle. The regulator device comprises a support and at least one electronic component configured to participate in the control of the electric machine. The support comprises a first part on which the at least one electronic component is mounted. The first part having an edge equipped with a brush holder provided with at least one brush-holder receptacle configured to accommodate a brush for making an electrical connection with a rotor of the electric machine. The device is configured to allow air to flow through the first part of the support, in contact with the brush holder. The device includes at least one air circulation slot provided through the support between the first part and the brush-holder. The support covers an air opening in the bearing.

An electrical machine such as an alternator or starter-alternator for a motor vehicle which is fitted with the one-piece voltage-regulator/brush-holder assembly (). The brush-holder () is capable of guiding at least first and second brushes by means of respective first and second longitudinal recesses (). The recesses are substantially parallelepiped, made of an electrically insulating material and extend substantially in an axial plane of a rotor of the machine. Each recess is provided with at least one respective longitudinal internal groove () in communication with at least one channel () provided in a body () of the assembly (), in an axial direction (XX') of the rotor, and intended for a coolant () to pass therethrough. A first cross section of the first internal groove is between 5% and 7% of a second cross section of the recesses.
