Embodiment Construction

[0030] figure 1 A rotating electrical machine 10 is shown comprising a multiphase stator 11 surrounding a rotor 12 mounted on a shaft 13 having an axis X. As shown in FIG. The stator 11 surrounds the rotor 12 with an air gap between the inner periphery of the stator 11 and the outer periphery of the rotor 12 . The stator 11 is installed in a housing 14 provided with a front bearing 17 and a rear bearing 18 carrying the rotating shaft 13 . To this end, a bearing 15 is interposed between the shaft 13 and the bearings 17 , 18 .

[0031] The electric machine 10 can be coupled via a pinion 16 to a gearbox belonging to the drive train of the motor vehicle. In order to ensure the rotational connection between the shaft 13 and the pinion 16, a subassembly with a complementary shaped groove 22 can be installed between these two elements, as in figure 2 and 3 shown.

[0032] The electric machine 10 can be operated in alternator mode, in particular to supply energy to the vehicle's...

Abstract

The invention mainly relates to a rotating motor which comprises a rotor (12) that is mounted on a shaft (13). The rotor (12) has a body (23) and a magnet which is at least partially accommodated in the body (23). The rotor (12) is provided with two holding flanges (27,28) for holding the permanent magnet (24) in the rotor body (23). The holding flanges (27,28) is fastened at the axial end of therotor body (23). The rotating motor is characterized in that each holding flange (27,28) is provided with at least one separable part (37) for balancing the rotor.

Description

technical field [0001] The present invention relates to rotating electrical machine rotors equipped with improved balancing flanges. Background technique [0002] In known manner, a rotating electric machine comprises a stator and a rotor integral with a shaft. The rotor may be integral with the drive and / or driven shaft and may belong to a rotating electric machine in the form of an alternator, an electric machine or a reversible electric machine capable of operating in both modes. [0003] The stator is mounted in a housing configured as a shaft which is carried in rotation on bearing housings by means of roller bearings. The rotor has a body formed by a stack of laminated sheets held in the shape of a bundle by suitable attachment units. [0004] The stator has a body consisting of a stack of thin laminates forming a crown, the inner side of which is equipped with slots open towards the inside to receive the phase windings. These windings pass through slots in the stat...
