Embodiment Construction

[0043] Unless otherwise stated, identical elements shown in different figures have a single reference sign.

[0044] The invention relates to a rotating electrical machine 1 , in particular for a motor vehicle. The rotating electric machine 1 according to the invention may be in the form of an alternator, an electric motor or a reversible electric machine capable of operating in two modes.

[0045] figure 1 The overall structure of the rotating electric machine 1 is schematically shown.

[0046] refer to figure 1 A rotating electric machine 1 includes a stator 2 and a rotor 7 fitted on a shaft 8 . The shaft 8 is mounted for rotation about the axis of rotation X by means of bearing means 81 and 82 , for example ball bearings. The bearing devices 81 and 82 are supported by the rear support 31 and the front support 32 forming the housing 3 of the rotary electric machine 1 .

[0047] The stator 2 comprises a main body 21 , supported by the housing 3 , in the form of a stack o...

Abstract

The invention concerns a rotating electrical machine, in particular for a motor vehicle, comprising: a stator body, a stator winding carried by the stator body, a winding lead-out wire (23) protrudingwith respect to an end (211) of the stator body, a housing, carrying the stator body, comprising a bearing (31) positioned opposite the winding lead-out wire (23) of the stator, a sensor (4), a wedging element (5) positioned on a top portion (311) of the bearing (31), said wedging element (5) being constructed and arranged to compress the sensor (4) against the winding lead-out wire (23).

Description

technical field [0001] The invention relates to the general field of motor vehicles. More specifically, the invention relates to a rotating electric machine of a motor vehicle comprising a sensor, such as a temperature sensor, and elements for wedging the sensor in the winding bun of the electric machine. A rotating electric machine is for example an alternator, an electric motor or a reversible electric machine which can operate in two modes. Background technique [0002] Rotating electrical machine 1 (an example of which is in figure 1 ) includes a stator 2 and a rotor 7, the rotor 7 is separated from the stator 2 by an air gap (not shown). The rotor 7 is integral with a shaft 8 rotating about an axis X of rotation. Furthermore, the housing 3 supports the stator 2 and comprises at least one rear flange (referred to as rear support 31 ) and a front flange (referred to as front support 32 ). [0003] exist figure 2 The stator 2 , shown more clearly in , comprises a bod...
