Problems solved by technology

However, the paths that make it possible to connect ground to electronic components are not direct and can be longer or shorter and are therefore inductive depending on the arrangement of the vehicle
Especially due to voltage drops in the supply circuit of the motor, there will be an offset between the chassis ground and the ground of the electronic components
This type of offset causes electromagnetic compatibility issues with the motor environment

Abstract

The present invention relates to a rotating electrical machine, particularly for a motor vehicle. The machine comprises active parts: a casing (11), a brush holder (24) comprising at least one brush (23), an electrical excitation trace (44) of said brush and a housing (37) formed by an electrically insulating material, a fixing device (49) for mounting the brush holder (24) in said machine and anelectronic assembly (36) comprising a control module (61) and an excitation trace (48) connecting the excitation trace (44) of the brush holder to said control module. The electronic assembly (36) comprises a ground trace (63), said ground trace being electrically connected to the control module (61) and to the casing (11) by means of the fixing device (49).

Description

technical field [0001] In particular, the invention relates to a brush holder for a rotating electrical machine. Background technique [0002] The invention has a particularly advantageous application in the field of rotating electric machines such as alternators, alternator starters or reversible electric machines. It should be remembered that a reversible electric machine is a rotating electric machine which can work reversibly, first as a generator functioning as an alternator, and then as an electric motor, for example in order to start the heat engine of a motor vehicle. [0003] A rotating electrical machine consists of a rotor that is movable in rotation about an axis and a stationary stator surrounding the rotor. The rotor, stator, and shaft are assembled in a housing that also supports the electronic components that control the operation of the motor. In alternator mode, as the rotor spins, it induces a magnetic field on the stator, which is then converted into el...
