Method for producing the coil of a rotary electric machine stator and stator thus obtained

A method of producing a stator for a rotary electrical machine comprising a body in which axial recesses are produced and comprising a plurality of conductors arranged in the recesses, which comprises a step of depositing conductors on a linear support that comprises transverse recesses, comprising a first phase of depositing conductors in the recesses in the support in order to form a first layer of conductors, and a second phase of depositing conductors in the recesses, in order to form a second layer of conductors that is arranged vertically above the first layer; the first deposition phase and the second deposition phase consists of depositing one and the same conductor on the linear support. The invention also proposes an arrangement of a set of conductors on a linear support obtained at the end of the deposition step.

Method for producing a rotary electric machine stator

The disclosure relates to a rotating electrical machine (), in particular an alternator or an alternator-starter for a motor vehicle. At least one bearing mount () is provided with at least one opening () opening onto the exterior of the bearing mount. A stator () comprising an electric coil () is provided. This coil includes a plurality of electric conductors, at least one of which includes an end forming an electrical neutral point of the coil. The machine further includes an electrical insulation member () configured to prevent any contact between the bearing mount () and said neutral point-forming conductor end. The insulation member extends at least partially through the opening of the bearing mount and is at least partially outside the bearing mount. The electrical insulation member being furthermore configured to rest at least partially on an outer surface () of the bearing mount.

Rotating electrical machine

A rotating electrical machine stator comprising an annular cylindrical body including axial grooves, and at least one phase winding including corrugated turns of wire, the phase winding comprising a first outer half-phase and a second inner half-phase which are radially superimposed, the first outer half-phase including outer leading-out wires projecting from the radial walls of the body and the second inner half-phase including outer leading-out wires projecting from the radial walls of the body. The invention is characterized in that for each phase winding, the wire length of each turn of the inner half-phase is greater than the wire length of each turn of the outer half-phase. The invention also concerns a phase winding designed to be mounted in such a rotor.
