Problems solved by technology

[0006] In such an interconnector known from document US 2014 / 0183993, the operation of electrically connecting parts of the winding conductors to the tabs of the interconnector may become complicated due to the fact that the parts of the conductors are not connected in particular to the The proximity between the rear bearings and the connecting part of the conductors creates a large space at the end of the connecting operation, which in particular poses a risk of salt bridge formation

Embodiment Construction

[0065] figure 1 A compact and multi-phase rotating electrical machine 10 is shown, in particular for motor vehicles. The rotating electrical machine converts mechanical energy to electrical energy in alternator mode and can function in motor mode to convert electrical energy to mechanical energy. For example, the rotating electric machine is an alternator or a reversible machine.

[0066] The rotating electric machine includes a housing 11 . Inside the housing it also comprises a shaft 12, a rotor 13 connected in rotation with the shaft and a stator 14 surrounding the rotor. The rotational movement of the rotor 12 takes place around the X-axis, which is the axis of the motor. In the following description, radial, orthogonal radial and axial orientations shall be considered with respect to this X-axis. In the following description, the rear part is the part of the motor including the electronics, and the front part is the part of the motor on the pulley side.

Abstract

The invention mainly concerns an interconnector (30) for interconnecting two conductors of a stator winding (24) of an electric machine, extending over an angular sector (alpha) about an axis X, the interconnector (30) comprising at least two angularly offset electrically conductive tabs (31, 32), each electrically conductive tab having a radial end surface (300) defining a connection surface for a conductor portion (240) of the winding of the electric machine, each fastening tab having a free end (301) and the distance between the tab and the axis varying towards the free end of the tab.

Description

technical field [0001] The invention relates to an interconnector having a connection tab of a portion of a winding conductor which is angled relative to the axis of the machine in which the interconnector is assembled. Background technique [0002] A rotating electrical machine is formed in a manner known per se from a stator and a rotor connected to a shaft. The rotor may be connected with a leading and / or guided shaft, which may belong to a rotating electrical machine in the form of an alternator, an electric motor or a reversible machine, acting in both modes. [0003] Furthermore, the stator is mounted in a housing configured to rotate the shaft, for example via bearings. The stator has a body formed from a stack of sheets forming a crowned cylindrical head fitted with recesses open to the inside to accommodate the windings. [0004] In corrugated windings, each phase bearing consists of at least one winding conductor, such as a continuous wire coated with an insulati...
