  • Patent number: 11336140
    Abstract: The invention mainly concerns a coiling procedure of a stator for a multiphase electrical rotating machine: the said stator comprising grooves, each intended to take up an uneven number of conductors of a coil, the said coil comprising two systems, each comprising one group of conductors (C1-C3, C1?-C3?) respectively, the said procedure comprises stages of installation of the conductors (C1-C3, C1?-C3?) into the said grooves, repeated in order to form a coil comprising several turns (S1-S9) completed alternately according to a first direction of rotation (K1) and according to a second direction of rotation (K2) opposite the first direction of rotation, with the characteristic that at least two changes of direction of rotation (CH1-CH8) from one turn to the other are carried out in different angular zones.

  • Patent number: 11159070
    Abstract: The invention proposes a stator for a rotating electric machine, in particular for a motor vehicle, the stator (15) including: —a body (27) including notches (37) that are opened radially into an internal wall (40) of said body, —at least one winding (43) forming a phase of the stator, the winding formed from turns (54) includes a first half-phase (49) and a second half-phase (50) that are superposed radially in the notch (37), each turn including a series of axial strands (44) that are received in a series of associated notches and connecting strands (45, 46) that connect the successive axial strands (44) by extending alternatively to protrude with respect to the body (27). A length of wire of each turn of one of the half-phases is larger than the length of wire of each turn of the other half-phase. Furthermore, one of the half-phases has a number of turns higher than that of the other half-phase.

  • Publication number: 20200067363
    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), —at least two windings (43), each forming a phase of the stator (15), each winding comprising modulating 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 axial strands (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.

  • Publication number: 20180034351
    Abstract: The invention relates mainly to a method for winding a stator for a multiphase electric machine, the stator comprising notches and intended to receive conductors of a winding, the winding comprising, for each phase, a coil and forming two systems each comprising a respective group of coils, the method comprising steps of installing conductors in the repeated notches in such a way as to form a winding comprising a plurality of concentric turns, wherein one of the steps of installing the conductors in a series of notches is subdivided into a first step of installing the conductors of a first turn of the first system; followed by a second step of installing the conductors of the first turn of the second system while the first step of installing the conductors of the first system continues.

  • Publication number: 20170257000
    Abstract: The invention relates mainly to a rotary electrical machine stator, in particular for a motor vehicle, comprising: a stator body (11) with a central axis, the stator body (11) comprising a series of notches (15); a winding wound in the notches (15) in the stator body (11) forming a first chignon (231) and a second chignon (232) extending axially on both sides of the stator body (11); wherein at least one of the phase windings (PH1-PH3, PH1?-PH3?) is a shielded winding which comprises all the active portions (20) of the layer (C1, CN) situated at one of the radial ends at least of each notch (15) of the series, each extended firstly by a corresponding connection portion (21) of the first chignon (231), and secondly by a corresponding connection portion (21) of the second chignon (232).

  • Publication number: 20110111091
    Abstract: A method, termed “bionative” method, for preparing a leaven, in which: a raw milk is selected from the group formed from raw milks of which the pH is capable of reaching, during a step of stabilising fermentation by acidifying lactic fermentation of the raw milk, at least one selection temperature, a value of 5.5 in more than 15 h, and a minimum value of 5.0 in less than 48 h, and then a raw milk-stabilising treatment is carried out. The treatment includes at least one step, termed stabilising fermentation step, of acidifying lactic fermentation of a fermentation medium, including a first stabilising fermentation step carried out using a fermentation medium including the raw milk, in which at least one stabilising fermentation step is interrupted when the pH of the fermentation medium reaches a value of between 4.9 and 6.0.
