Description
Technical Field
The present invention relates to a rotor for a rotating electrical machine, in particular for an alternator or starter-alternator. The invention is particularly advantageous, but not exclusively, in the field of rotating electrical machines for hybrid vehicles, in particular motor vehicles, and in particular in the field of high-power reversible electrical machines capable of operating in alternator mode and motor mode and coupled with gearboxes.
Background
In a manner known per se, a rotating electrical machine has a stator and a rotor fixed to a shaft. The rotor may be fixed to the drive shaft and/or the driven shaft and may belong to a rotating electrical machine in the form of an alternator, an electric motor or a reversible machine capable of operating in two modes.
In certain types of motor vehicle drive trains, a high-power reversible rotating electrical machine is coupled to the gearbox of the vehicle or to the axle system of the motor vehicle. Thus, the electric machine is operable in an alternator mode to provide energy, in particular, to the battery and/or to the on-board network of the vehicle, and in a motor mode to power the vehicle not only by starting the internal combustion engine, but also alone or in combination with the internal combustion engine.
The stator has a body formed by a stack of thin laminations forming a ring, the inner face of the body being provided with slots open towards the interior for receiving the phase windings. These windings pass through the slots of the stator body and form visible portions protruding on either side of the body of the stator. The windings may be obtained, for example, from continuous wires covered with enamel or from conductive elements in the form of pins, which are connected to each other by welding.
Furthermore, the rotor has two pole wheels, each with an end plate and a pole at its outer periphery, the claw being directed axially in the direction of the end plate of the other pole wheel. The claws of the pole wheel nest with one another. The core is axially interposed between the end plates of the pole wheel. The core carries on its outer periphery an excitation winding comprising a plurality of turns formed around an insulator interposed radially between the core and the winding.
Assemblies of this type are known in the prior art and are widely used in alternators for motor vehicles. One constant goal in this field is to reduce the temperature of the rotor during its operation.
The present invention therefore aims to provide a rotor for a rotating electrical machine with improved cooling.

Conventionally, the "radial" orientation is orthogonal to the axial orientation. Depending on the context, the axial orientation is related to the rotational axis of the rotor, stator and/or motor. The "circumferential" orientation is orthogonal to the axial direction and orthogonal to the radial direction. The terms "outer, outer" and "inner, inner" are used to define the relative position of one element with respect to another element with respect to a reference axis, as opposed to an outer element located radially at the outer periphery, an element near the axis thus being described as an inner element.
Preferably, the recess axially exposes two to six turns of the excitation winding. More preferably, the recess axially exposes two to four turns of the excitation winding.

Detailed Description
Fig. 1 shows a rotor 1 for a rotating electrical machine for an alternator, starter-alternator, reversible machine or electric motor, which is mounted for rotation about an axis of rotation X-X'. The rotor 1 is force fitted to a shaft 2 extending along an axis X-X 'and rotated about the axis X-X' by means of splines carried by the shaft 2, which are fitted with grooves formed in the rotor 1.
The rotor 1 is a claw-pole rotor with two pole wheels 8a, 8b. As shown in fig. 3, each pole wheel 8a, 8b comprises a cylindrical half-core 34, which cylindrical half-core 34 carries on its outer periphery an excitation winding 10 comprising a plurality of turns 11. The winding 10 is insulated from the core 34 by an insulator 20 interposed radially between these elements. The insulator is made of an electrically insulating material, advantageously a plastic material.
Each pole wheel 8a, 8b further comprises a disc-shaped end plate 18 and a claw 9a, 9b, the end plate 18 being centred on and substantially perpendicular to the axis X-X', the claw 9a, 9 being directed axially in the direction of the end plate 18 of the other pole wheel 8a, 8b. The end plate is pierced by a central hole receiving the shaft 2. Throughout the description and the claims, "substantially radial" is understood to mean a direction forming an angle between 80 ° and 100 ° with respect to the axis X-X'.
In the embodiment considered, the core consists of half-cores 34, each of which is integrally formed with one of the two pole wheels 8a, 8b. The half core 34 has a smaller outer diameter than the end plate 18 and extends from a large axial face thereof, which faces the opposite pole wheel. When the two pole wheels 8a, 8b are assembled as shown in fig. 3, the two half cores 34 are placed axially continuous with each other. The core is pierced by a hole that receives the shaft 2, in a variant embodiment the two half-cores 34 may be a single piece and may be independent of the pole wheels 8a, 8b.
As shown in fig. 3, the insulator 20 comprises a bottom 31 and two rings 32, the bottom 31 radially surrounding the core 34 and interposed between the winding 10 and the core 34, the two rings 32 being substantially perpendicular to the axis X-X'. The bottom 31 is itself cylindrical and coaxial with the rotation axis X-X'. The ring 32 is joined to and projects radially outwardly from two opposite axial ends of the base. These rings 32 are interposed axially on either side of the excitation winding 10, between the excitation winding 10 and the end plates 18 of the two pole wheels 8a, 8b.
Each ring 32 comprises petals (not visible in the figures) regularly spaced along the radially outer edge of the ring and bent axially between the windings 10 and the jaws 9a, 9 b.
The rotor 1 has a first recess 13 and a second recess 14 in order to axially expose at least one turn 11 of the excitation winding 10, as is visible in fig. 2.
Thus, when the rotor 1 of the present invention is viewed axially along the axis X-X', at least one turn 11 of the winding 10 can be seen by the presence of the recesses 13, 14. In other words, the pole wheels 8a, 8b do not extend radially on the outside of the entire circumference of the winding 10 or beyond the entire circumference. Thus, at least a portion of the axial ends of the winding 10 do not face the pole wheels 8a, 8b or the insulator 20. This portion therefore consists of turns 11 of the winding 10 that are axially visible.
As shown in fig. 1 to 3, the rotor 1 has at least one space between at least one turn 11 of the winding 10 and the axial end faces of the pole wheels 8a, 8b facing the turn, which is free of any components.
The term "recess" may also be understood to mean "opening". Thus, there may be, for example, a case in which the insulator 20, in particular the ring 32, is of the type in the form of a grid and extends radially at least at the same height as the turns 11 positioned radially on the outside, while at least one turn 11 is exposed axially.
Advantageously, at least one pole wheel 8a, 8b and the insulator 20 are shaped so as to axially expose at least one turn 11. Advantageously, the structure and/or shape of at least one pole wheel 8a, 8b and/or of the insulator 20 is defined so as to axially expose at least one turn 11.
In the embodiment considered, the first recess 13 is formed on at least one pole wheel 8a, 8b. The second recess 14 is formed on the insulator 20 of the excitation winding 10, in particular on the ring 32.
The claws 9a, 9b, also called teeth, have a trapezoidal shape. The claws 9a, 9b of the same pole wheel 8a, 8b are connected to the end plate 18 by respective bases 19 protruding radially from the outer edge of the end plate 18 and extend axially from the bases 19. The pole wheels 8a, 8b are angularly offset relative to each other such that each jaw 9a, 9b of a pole wheel 8a, 8b is interposed between two adjacent jaws of the other pole wheel 8a, 8b. Thus, the jaws 8a, 8b nest with each other.
The claws 9a, 9b of the same pole wheel are formed by having an inner diameterIs separated from each other by the inter-paw space 15. Diameter->As well as to define the outer periphery of the end plate 18. Thus, as shown in FIG. 4, diameter +.>Defining an inner diameter of each inter-jaw space 15 and an outer diameter of the end plate 18. Thus, by traveling along the perimeter of end plate 18, the inter-paw spaces are alternately encountered15 and a base 19. The inter-claw space 15 is thus delimited by two consecutive claws of the pole wheel, in particular two lateral faces facing each other, belonging to two consecutive claws 9a or 9b of one and the other of the pole wheels 8a, 8b, respectively. In other words, and as can be seen in particular in fig. 2 and 4, each inter-jaw space 15 is delimited by an arcuate bottom at the periphery of the end plate 18, two lateral solid sides 5 of the base 19 bounding the space 15, and a radially outer open side. In the example considered, the inter-jaw space 15 forms a first recess 13.
As shown in fig. 5, the jaws 9a, 9b have a radially external face 38 inscribed coaxially with the rotation axis and defining the external diameter of the rotorIs provided. These faces 138 considered in a plane perpendicular to the rotation axis X-X' have respective widths tapering from the base 19 towards the opposite pole wheel.
The jaws 9a, 9b also have a radially internal face 39, the slope of the radially internal face 39 forming an intersection ibg with the respective base 19, the intersection ibg being inscribed coaxially with the rotation axis and defining the internal diameter of the jawIs provided.
A comparative example between a rotor (R1) according to the invention, i.e. with recesses axially exposing at least one turn of the excitation winding (as shown in fig. 1 to 6), and a reference Rotor (RF) without recesses axially exposing at least one turn of the excitation winding will now be presented. In rotor R1, inter-jaw diameterReduced RF relative to the rotor.
The characteristics of the two rotors are given in table 1 below.
[ Table 1 ]
The temperatures of these two rotors during operation according to the rotational speed are shown in table 2 below.
[ Table 2 ]
| Rotational speed (rpm) | 1800 | 2400 | 3000 | 4000 | 5000 | 6000 |
| T℃RF | 184 | 191 | 192 | 183 | 177 | 169 |
| T℃R1 | 182 | 188 | 190 | 181 | 175 | 166 |
Thus, when the inter-jaw diameter 15 is reduced to have a recess exposing at least one turn of the excitation winding, the temperature of the rotor R1 according to the invention is reduced by about 3 ℃ relative to the reference rotor RF.
Preferably, the rotor according to the invention has a ratio R defined by the following relationship:r is less than 90%, preferably less than 88%.
Preferably, the ratio R is greater than or equal to 85%. Specifically, beyond this ratio, the protruding amount (overlap) of the holding claw becomes excessively large.
As shown in fig. 6, the inter-jaw space 15 has a first surface S1 and a second surface S2 that are triangular in shape as a whole, in which:
for the first surface S1, the base is coaxial with the rotation axis X-X' and defines the outer diameter of the rotorFor the second surface S2, the base is coaxial with the rotation axis X-X' and defines the inner diameter of the pawl +.>Is tangent to the main body of the (c),
the lateral surfaces are defined by two consecutive claws 9a, 9b of the same pole wheel 8a, 8b, in particular by two lateral surfaces of the two claws 9a, 9b facing each other,
the apex is defined by an inner diameter coaxial with the axis of rotation X-XIs defined as the tangent to the cylinder.
Rotor R1 has a ratio S2/S1 of 17.75%.
The claws 9a, 9b are configured for mounting a polar magnet 40. In the embodiment considered, each jaw 9a, 9b comprises two channels having a U-shaped profile and made in the lateral faces of the jaw. The channel is a channel for receiving the permanent magnet 40, the permanent magnet 40 being of, for example, rare earth type or made of iron. The choice of the type of magnet depends on the desired power of the motor comprising the rotor 1. The magnet may be manufactured by moulding, in particular by sintering. As a variant, the magnet 40 is a component made of a magnetic elastic ferrite material.
In this case, the permanent magnet 40 is generally parallelepiped-shaped and is mounted in a channel, the dimensions of which are set according to the channel so as to enter the channel.
The rotor 1 may comprise two fans, each pressed and welded to the axial face of the end plate 18 of one of the pole wheels 8a, 8b, said face facing away from the other wheel. The fan makes it possible to generate an air flow inside the rotor 1 to cool it.
Of course, the above description is given by way of example only and does not limit the scope of the invention, which does not deviate by substituting various elements with any other equivalent.
Furthermore, various features, modifications, and/or embodiments of the invention may be combined into various combinations as long as they are not incompatible with or exclusive of each other.
