Problems solved by technology

In fact, this leads, firstly, to an increase in the size of said machine and, secondly, to a decrease in its performance, since it is known that the current flowing in the bun produces losses
In addition, this also increases the production cost of the machine by increasing the amount of conductors required to produce the windings

Abstract

The invention provides a stator for a rotating electric machine, in particular for a motor vehicle, said stator (15) comprising: - a main body (27) comprising a recess (37), said recess being axially open into the front axial end wall (38) and the rear axial end wall (39) of said main body (27), and radially open in the inner wall (40) of said main body (27); - at least two windings (43), each winding forming a phase of said stator (15), each winding comprising undulating turns comprising a series of axial strands (44) and comprising connecting strands (45,46), said axial Axial harnesses are received in a series of associated notches (37), said connecting harnesses connecting successive axial harnesses (44) and extending alternately beyond the front axial end wall (38) and beyond the rear axial end wall ( 39) Extend. One winding has a longer wire length than the other windings.

Description

technical field [0001] The invention relates in particular to a wound stator equipped with windings forming phases of a rotating electrical machine for a motor vehicle. Background technique [0002] The invention has a particularly advantageous application in the field of rotating electric machines, such as alternators, alternator-starters or reversible machines. It should be noted that a reversible machine is a rotating electric machine that can work reversibly, on the one hand as a generator when operating as an alternator, and on the other hand as an electric motor, such as a heat engine for starting a motor vehicle. [0003] A rotating electric machine comprises a rotor movable in rotation about an axis, and a stationary stator surrounding the rotor. In alternator mode, as the rotor spins, it induces a magnetic field on the stator, which converts this field into electrical current to power the vehicle electronics and recharge the battery. In motor mode, the stator is p...
