Embodiment Construction

[0066] figure 2 A voltage regulator assembly 100 is shown with a brush holder that can replace, for example, figure 1 A voltage regulator assembly 14 with brush holders in a rotating electric machine is shown.

[0067] For this purpose, the voltage regulator assembly with the brush holder specifically includes (not in figure 2 shown in):

[0068] - Figure 5 and 6 The brush holder 214 shown in. Brush holder 214 includes brushes 215, which can be figure 1 The rotor 2 of the rotating electrical machine shown is in electrical contact to provide an excitation signal thereto;

[0069] - Microcontroller 312 for conditioning the excitation signal, such as Figure 7 shown.

[0070] The voltage regulator assembly 100 with brush holder also includes a body made of electrically insulating material which is in the form of a "T" and consists of two parts:

[0071] - a first part 200 formed as a central part of a body in the form of a "T" and extending according to a first axis (...

Abstract

A voltage regulator with brush holder assembly (100) for a rotary electric machine intended for an automotive vehicle, which assembly comprises: -a brush holder comprising brushes that are capable ofcoming into electrical contact with a rotor of the rotary electric machine in order to apply an excitation signal thereto; -a microcontroller for regulating said excitation signal; -a body made of electrically insulating material, said body taking the overall shape of a T and in which said brush holder and said microcontroller are housed, characterized in that the voltage regulator with brush holder assembly (100) comprises two parts: -a first part (200) forming a central portion of the T-shaped body and extending along a first axis (z1-z2), said first part (200) comprising a housing (201) foraccommodating the brush holder and a second part (300) forming a lateral portion of the T-shaped body and extending along a second axis (y1-y2) perpendicular to said first axis (z1-z2), said integrated circuit being housed in said second part (300).

Description

technical field [0001] The invention relates to a voltage regulator with a brush-holder for a rotating electric machine, in particular an alternator or alternator-starter of a motor vehicle, and a rotating electric machine comprising an assembly of this type . Background technique [0002] In the prior art, many rotating electric machines are equipped with current rectification means and voltage regulator assemblies with brush holders. For example, figure 1 An electric machine in the form of such a compact polyphase alternator is shown, especially for motor vehicles. This alternator, which in this case has internal ventilation, converts mechanical energy into electrical energy. The electric machine basically comprises a housing 1, inside the housing a rotor 2 rotating integrally with a shaft 3 and a multiphase stator 4 which surrounds the rotor in the presence of a slight air gap and consists of a notched A set of bodies in the form of sheet metal, said notches, in the c...
