Definitions
- the present invention relates to a rotating electrical machine such as an alternator or an alternator or a reversible machine or an electric motor for a motor vehicle.
- the invention relates more particularly to a stator for a rotating electrical machine comprising a winding made from conductive pins.
- the stator comprises a cylinder head forming a piece of revolution about an axis passing through the center of the stator.
- the yoke has radial teeth, extending radially towards the center of the stator and around which the electric winding is made. More particularly, the radial teeth delimit between them notches in which conductive elements participating to form the stator winding pass.
- the winding of the stator can be realized in different ways, for example by means of a needle device guiding the winding of the same electrical wire around each radial tooth to form successive turns. Nevertheless, this embodiment involves a difficulty of implementation to set the path of the needle guiding the electric wire through the notches. In particular, this embodiment may not be possible when the angular spacing between two successive radial teeth is not sufficient to allow the passage of the carrier needle of the wire to be wound around the teeth.
- the conductive pins are each mounted in two separate notches by engagement of a segment in a respective notch, of so that the conductive segments of the same conductive pin occupy two different notches of the annular body.
- the conductive segments of the same pin are located on separate layers and separated by a single intermediate layer formed by a conductive segment of another conductive pin.
- the free end that is to say the end which emerges at the level of the second axial end face of the annular body, a conductive segment of a pin occupying the layer Ci in a notch is connected, at the second axial face of the annular body, to the free end of a conductive segment of a neighboring pin occupying the layer Ci + i in a notch separated by a pitch P.
- said conductive segments connected to a current source are housed in a central layer, that is to say the second or the third layer and more particularly the third layer.
- FIG. 5 represents a perspective view of a portion of the stator illustrated in FIG. 1;
- the two sets of pins form a first so-called outer set, which comprises pins whose conductive segments are housed in the notches so as to form the first outer layer and a second set said inner, which has pins whose conductive segments are housed in the notches so as to form the fourth inner layer.
- connection portion may be chosen to arrange the connection portion above the bent junctions of the corresponding conductive pins, especially if congestion constraints are stronger in radial dimensioning than axial , it being understood that the position of this electrical connection strip in the first layer C1, made possible by the interlocking of the conductive pins and the resulting mixture between the so-called inner pins and the so-called outer pins, makes it possible to choose the orientation of the connection portion and the resulting space according to the rotating electrical machine on which this coil is implanted.
- these additional conductive segments can occupy distinct layers such as the first layer Ci and the fourth layer C4.
- the connecting portion of the electrical connection strip extends partly above, in an axial direction, some bent junctions of the other conductive pins.
- a conductive segment 24 is provided to occupy a second layer C2 in an E + P notch spaced by a pitch P.
- the current flows in the conductive segment 21 housed in a notch E, in the extension of the phase current input 211 (arrow Fl).
- This conductive segment 21, arranged to form part of the third layer C3 in this notch E, has at its free end, on the side of the second axial end face 14, a folded shape on itself similar to that of a conductive segment 16C of an outer pin that it replaces in this layer.
- this conductive segment 21 is connected, at the second axial end face 14 of the stator, to the free end 17B of a conductive segment 16D occupying the fourth layer C4 in a notch EP, the two free ends, arranged next to each other as can be seen more particularly in FIG. 8, of these conductive segments 21, 16D being connected electrically at a point of contact 19B.
- the current is circulated from the second axial end face 14 to the first axial end face 12 in the fourth layer C4 of the notch EP, as illustrated by the arrow F2.
- the conductive segment 16D occupying the fourth layer C4 in the notch EP, forms part of a conductive pin 15B belonging to a second set of pins called inner set as it has been described above, so that this segment conductor is extended, at the first axial end face 12 of the stator, through an angled junction 18, into a conductive segment 16B occupying the second layer C2 in a notch separated from a space P, in the opposite direction to the first direction of orientation.
- the current is circulated from the first axial end face 12 to the second axial end face 14 in the third layer C3 of the notch E + 2P, as illustrated by the arrow fs.
