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 present invention provides a stator for a rotating electrical machine, in particular for a motor vehicle, the stator (15) comprising: a body (27) having notches (37) which open axially into front(38) and rear (39) axial end walls of the body (27) and which are radially open in an inner wall (40) of the body (27), and at least two windings (43), each forming a phase of the stator (15), each winding comprising undulating wire turns which comprise a series of axial strands (44) received in a series of associated notches (37) and connecting strands (45, 46) which connect the successive axialstrands (44) and extend alternately beyond the front axial end wall (38) and beyond the rear axial end wall (39). One winding has a shorter wire length than the other winding.

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...
