Embodiment Construction

[0039] First, the figure 1 and 2 A description is provided of an example of an electric machine in which a regulator device according to the invention can be used.

[0040] Such as figure 1 As shown, the motor is especially designed as a polyphase motor, for example comprising a housing 1, and a shaft 3 inside the housing, a rotor 2 rotating integrally with the shaft 3, and a wound stator 4, which is in a small gap ( surrounds the rotor 2 in the presence of (not shown in the figure).

[0041] This stator 4 comprises, for example, a body in the form of a plate pack provided with notches for mounting the stator windings 4 , said notches being equipped with notch insulation. The stator winding comprises a plurality of phases, which may each comprise at least one coil forming a bun 5 on both sides of the stator body. The phase outputs are, for example, delta or star connected and are connected to connectors belonging to the means for converting alternating current into direct ...

Abstract

The invention relates to a voltage regulator device for a rotary electric machine, notably an alternator and / or an alternator / starter of a motor vehicle, said regulator device (14) comprising a support (34) and one or more electronic components (28) able to play a part in controlling said electric machine, the support comprising a first part (60) on which the component or components is or are mounted, said first part having an edge (62) equipped with a brush holder (50) equipped with at least one housing, known as the brush housing, capable of housing a brush (15) for making an electrical connection with a rotor (3) of the electric machine possible. According to the invention, said device is configured to allow air to flow through said first part of the support, in contact with said brush holder. The invention also relates to an assembly of a device for rectifying the current produced by the electric machine and of such a regulator device, to a bearing of an electric machine equipped with such an assembly and to an electric machine equipped with such a bearing.

Description

technical field [0001] The invention relates to a voltage regulator device for a rotating electrical machine, in particular polyphase, such as an alternator and / or alternator-starter of a motor vehicle. [0002] The invention also relates to a support for a rotating electric machine of this type equipped with a voltage regulator device of this type and a rectification device. [0003] Finally, the invention relates to a rotating electric machine of this type equipped with a bearing of this type. Background technique [0004] Motor vehicle alternators are known today comprising a wound stator surrounding a rotor and at least one excitation winding of the rotor. They operate as generators to power the vehicle's on-board network and charge its battery. To this end, the rotor of the alternator is driven by the heat engine of the vehicle via a motion transmission device and its excitation winding is supplied with an electric current, known as excitation current. The thus magne...
