Definitions
- the present invention relates to an electrical transmission of mechanical power intended in particular for a motor vehicle transmission.
- the transmission of mechanical power between a source of motive movement and the element to be driven very often requires an adaptation of speed according to the operating regimes. This is particularly the case on motor vehicles where the internal combustion engine must be able to drive the wheels from a standstill to their maximum speed: the transmission then usually includes a coupling device allowing an at least temporary slip (clutch at friction, electromagnetic powder clutch, hydraulic torque converter) associated with a mechanical gear ratio with variable ratio (gearbox with discrete ratios, mechanical device with continuously variable ratio). This requirement to adapt speed is also found in the training of certain accessories.
- the electrical transmission in particular for a motor vehicle, comprising two electrical machines, the shaft of one of the electrical machines being connected to a source of motive energy, this machine converting mechanical energy into electrical energy, the other electrical machine converting electrical energy into mechanical energy, its shaft being connected to the element to be driven, the rotors of the two machines being arranged concentrically or axially with respect to each other, these two rotors cooperating with stators, the windings of which are arranged inside the space defined by the two rotors, is characterized in that the said windings comprise several annular windings juxtaposed in said space, these windings being supplied by alternating currents out of phase with each other.
- the arrangements according to the invention provide compactness gains linked to the high integration as well as efficiency gains which arise in particular from a reduction in Joule losses linked to the favorable arrangement of windings and, in the case of compound current control, the pooling of these as well as a reduction of losses in power electronics.
- the present invention provides for the arrangement of several annular windings juxtaposed in the space between two rotors. This arrangement makes it possible to supply the windings with alternating currents out of phase with each other.
- This transmission can also be used as a double traction motor with two independent drive shafts and electrically ensuring the "differential" function.
- one of the rotors is mounted in rotation on the shaft of the other rotor and drives in rotation a shaft offset axially from the shaft of the first rotor;
- the stator windings are arranged in the annular space between the two rotors and comprise a first annular layer of windings cooperating with one of the rotors, surrounding a second annular layer of windings cooperating with the other rotor, the two annular layers of windings being mechanically linked to each other;
- each winding is disposed in a ferromagnetic material core laterally covered on each side by a ferromagnetic material flange comprising, opposite the rotor, claws engaged between the claws of the flange situated on the other side of the core;
- each winding is arranged in a core of ferromagnetic material laterally covered on each side by a flange of ferromagnetic material having teeth facing the rotor facing the rotor;
- each rotor has on its periphery a series of ferromagnetic studs extending opposite the stator windings;
- the annular space between the two rotors may comprise a single series of juxtaposed windings;
- the peripheral surfaces of the two rotors are adjacent to each other and the annular windings of the stator are located opposite the internal surface of the rotor which is located inside the other rotor;
- the transmission can comprise a stator constituted by several juxtaposed wafers each comprising an annular winding and bearing on their periphery ferromagnetic claws engaged between the claws of the periphery of the adjacent wafer, an intermediate rotor forming an asynchronous cage comprising conductive bars parallel to the axis of the rotor and a series of ferromagnetic studs located between the bars, this intermediate rotor being surrounded by an external rotor comprising conductive bars consisting of segments parallel to the axis of the rotor and offset

- FIG. 12 is an exploded view according to the principle of Figure 11 of an intermediate rotor arrangement with flow through and compound current control in an asynchronous cage configuration.
- FIG. 1 represents an electrical transmission, comprising an input shaft 1 connected to the motor, integral with a disc 2 carrying a magnetic element 3 of cylindrical shape centered on the axis XX 'of the shaft 1.
- a second disc 4 adjacent to the first disc 2.
- This second disc 4 carries a magnetic element 5 of cylindrical shape, annularly surrounding the first magnetic element 3.
- a first series of three annular coils 6 adjacent to the first element 3 and surrounded by a second series of three annular coils 7 adjacent to the second element 5.
- the annular coils 6 and 7 are integral with a fixed part 8.
- the coils 6 are connected to electronics 9.
- the coils 7 are connected to electronics 10.
- the electronics 9 and 10 are powered by a battery 11. P ar moreover, the disc 4 is connected by pinions 12, 13 to an output shaft 14 extending parallel to the input shaft 1.
- the armatures of the two electric machines have, on the stator, magnetic circuits organized around annular coils and united in adjacent spaces as shown in section in the block diagram of Figure 1.
- FIG. 1 there is shown in section three annular coils and their magnetic circuits placed side by side and centered on the common axis of revolution X-X '.
- the air gaps associated respectively with the armatures are cylindrical, that is to say crossed radially by the magnetic fluxes. Transposition with axial flow of the invention is however possible, as shown in the example of FIG.
- the magnetic coupling to its air gap of one of these windings can be achieved by a double system of claws as shown in exploded view in FIG. 2A.
- the multipolar flux collected at the air gap is thus globalized in the core (or yoke) on which the third winding is wound.
- FIG. 2B gives a schematic sectional view along a plane passing through the longitudinal axis; to facilitate understanding, the circulation of the flow in the stator is shown there, and an example of a rotor made up of a yoke taking the form of a ferromagnetic ring carrying radially magnetized surface magnets has been placed opposite this stator. and with alternating polarities.
- FIG. 2C completes this representation by a quarter-section view AA of FIG. 2B along the longitudinal axis.
- the reference 7 designates an annular winding.
- the reference 14a designates the ferromagnetic core or yoke of the winding 7.
- the reference 5 designates the rotor, shown here with surface magnets with a ferromagnetic flux looping yoke.
- the references 15 and 16 designate the double system of claws.
- the reference 17 shows the line of circulation of the magnetic flux between the rotor 5, the first claws 15, the core 14a of the winding- 7 and the second claws 16. It is understood that, by adapting the proportions given in these figures , and in particular by increasing the central bore in the core, one can thus constitute one of the magnetic circuits represented opposite the air gap 2 (external) in FIG. 1.
- this second assembly can be housed inside the central bore of the first, with an identical longitudinal thickness.
- “Wafer” will denote the assembly thus formed along an axial section of the machine and comprising for each armature an annular winding and the circuit associated magnetic, as well as the two rotor parts facing each other.
- Figure 1 therefore represents a machine consisting of three wafers.
- the active parts of the rotors can be produced in very many ways according to the usual principles of construction of electric machines: arrangements with surface magnets, inserted magnets, buried magnets, asynchronous cage, synchronous reluctant saliency, or combinations of these principles.
- the magnetic circuits as well to the stators as to the rotors, are traversed by alternating fluxes: to avoid the development of eddy currents within them, it is advisable to choose ferromagnetic materials electrically resistive.
- the traditional solution of "laminating" by juxtaposition of magnetic sheets isolated between them may be suitable in the portions of the magnetic circuit where the field lines remain substantially in the same plane; on the stator, however, the three-dimensional nature of the flow circulation invites the use of magnetic composite materials ("iron powders", Soft Magnetic Composites ”) such as those offered for example by the companies Hoganas in Sweden or Quebec Metal Powder in Canada.
- the pieces made of "iron powder” can be divided into smaller elements which are assembled.
- the good tolerances obtained in the forming of SMC parts generally avoids the need for resumption of machining. In arrangements comprising magnets, these must also be electrically resistive or else fragmented into isolated elements.
- each machine is based on the polyphase construction of the forces: at a given air gap i, the active parts of the stator and of the opposite rotor are successively offset by an angle of 2 ⁇ / n / pj in value relative, if we denote by i the number of pairs of poles on this air gap, that is to say the number of pairs of claws, and by n the number of phases.
- i the number of pairs of poles on this air gap
- n the number of phases.
- the relative angular offset between wafers can be obtained partially or completely both by playing on the successive angular position of the claw systems and on that of the active parts of the rotor.
- the number of wafers must be a multiple of the number of phases; in the representation of Figure 1 for example, each wafer corresponds to a phase: the system is three phase.
- the coupling of a winding to its air gap is obtained by a homopolar arrangement with variable reluctance with transverse looping of the flux to the rotor. This arrangement is illustrated in principle in Figure 3.
- the winding remains annular, but the coupling to the air gap is no longer by claws but by a double toothing.
- the teeth of each set of teeth are identical and opposite.
- the rotor carries a number of ferromagnetic studs corresponding to these pairs of teeth.
- NB to simplify the illustration, a single stud of this type appears in Figure 3.
- the studs allow a transverse magnetic connection between them: the maximum permeance associated with the winding is maximum; when, on the contrary, they are opposite the notches, the permeance is minimal.
- the reference 7 designates an annular winding.
- the reference 14a designates the ferromagnetic core or yoke of the winding 7.
- the reference 5 designates the rotor, constituted in this example by rotating ferromagnetic studs.
- the reference 18 designates two serrated ferromagnetic plates arranged on either side of the coil 7,
- the reference 19 designates the circulation of the magnetic flux between the rotor 5, the first plate 18, the yoke 14a and the second plate 18.
- the magnetic studs can be made of sheets or iron powders. Their assembly has not been shown: they can be linked together in an overmolded material that is electrically resistant and which will provide the mechanical connection to the rotor. As indicated above and generally for the arrangements according to the invention, it is necessary to take into account the magnetic couplings parasitized by the leaks between neighboring wafers.
- a first way of limiting this coupling consists in providing a non-magnetic space between the successive stators of the neighboring wafers. This space can for example be used to introduce a cooling circuit.
- Another means which may be more suitable for obtaining good axial compactness, consists in introducing this non-magnetic space between the successive magnetic parts of the rotors, at the borders between wafers.
- Figure 5 provides an exploded view indicative of a coil 7 and the double system of claws 15, 15a; 16, 16a associated therewith; the assembly is positioned opposite the two rotors 3, 5.
- the rotors 3, 5 have been shown schematically with surface magnets on the two air gaps; each of these groups of magnets is arranged on a ferromagnetic ring (respectively internal and external) which ensures the closure of the flow.
- the successive arrangement of the pancakes comprises an angular phase shift of 2 ⁇ / (nl.pl); this phase shift can be obtained either by playing on the angular setting of the group of magnets associated with this wafer at the air gap 1, or at the level of the group of corresponding claws of the rotor of the power source.
- the system is electrically with neither phases.
- the successive arrangement of the pancakes comprises an angular phase shift of 2 ⁇ / (n2.p2); this phase shift can be obtained either by playing on the angular setting of the group of magnets associated with this wafer at the gap 2, or at the group of corresponding fixed claws.
- the system is electrically with n2 phases.
- l is the relative angular position of the rotor associated with the air gap 1.
- a2 is the angular position of the rotor associated with the air gap 2.
- a single inverter replaces the two inverters previously required for separate armature arrangements like that in Figure 1. This single inverter has a number of arms corresponding to a common multiple of ni and n2 preferably the smallest common multiple .
- This number of arms corresponds to the number of wafers, unless each polyphase system has several groups of identical phases: in this case, the windings of the same setting can be connected in parallel or in series.
- the inverter can thus generate in each of the kl groups of wafers with ni phases a polyphase current system of pulsation ⁇ l; within a group, each current is successively phase-shifted by 2 ⁇ / nl and the sum of the currents is zero.
- the inverter can also generate in each of the k2 groups of wafers with n2 phases a polyphase current system of pulsation ⁇ 2; within a group, each current is successively phase shifted by 2 ⁇ / n2 and the sum of the currents is zero.
- the summation of the instructions makes it possible to obtain a superposition of the 2 polyphase systems, and a wafer i will be traversed by currents giving it a magnetic potential:
- ⁇ bf ⁇ hl .sm (p .a ⁇ + ⁇ l . ⁇ ) + ⁇ b2 .sm (p 2. 2 + ⁇ 2 -0 "1" 2 either again, replacing ni and n2 by their value in function of n: where ⁇ bl and ⁇ b2, ⁇ l and ⁇ 2 are amplitudes and phasagcs adjustable by electronic control.
- Figure 6 gives an equivalent diagram of the magnetic circuit thus defined on a wafer. Ferromagnetic parts have been idealized as conductors flow perfects (infinite permeances). The magnetic circuit is also considered to be linear.
- the permeances represented in gray form symbolize the escape routes; (leaks between prongs, leaks distributed over the winding). This diagram is globalized in FIG. 7.
- the magnetic coupling of the magnets with the claws is described by a set of permeances ⁇ + 1 or 2 and ⁇ -1 or 2 variable with the position and which integrate the air permeance and the permeance. internal magnet. We will admit that we can account for these variations by:
- ⁇ ala2 A ala2ma ⁇ - ⁇ s (Pl- a l .k 1 .l) .COS (p 2 .a 2. * 2- nn with, when the permeances of leakage can be overlooked:
- the question of the demagnetization limit does not arise in asynchronous or reluctance realizations; the elongation of the magnetic path resulting from the series of air gaps affects only the magnetizing components provided by the winding. - in return, significant reductions in Joule losses are possible; this is an important point to improve the efficiency and the thermal: in fact: with similar geometry, the magnetic potentials ⁇ bl and ⁇ b2 required to produce the torques are substantially preserved. Or.
- FIG. 9 gives an example of adaptation of an asynchronous cage on the air gap 1.
- the reference 21 designates the magnetic yoke of the cage, the reference 22, the surfaces of the ferromagnetic circuit, the reference 23 of the short-circuit rings at the ends of the cage, the reference 24 of the conducting bars and the reference 25 of the non-magnetic spaces. It is assumed here that the required phase shift between successive wafers is obtained by an angular offset at the level of the consecutive claw systems.
- the conductive bars arranged at regular intervals at the periphery of the rotor are thus substantially rectilinear and parallel to the longitudinal axis.
- NB depending on the shape of the claws and the space between them, it may or may not be desirable to give these bars an inclination relative to their reference direction, as is often done in the usual asynchronous machines for smoothing the powerful phenomena associated with the notching of the stator).
- the ends of the bars are electrically connected to each other on each side of the rotor by a conductive ring, according to the usual principle of asynchronous cages.
- a first feature relating to the electrical insulation of the busbars is however to be noted for this cage.
- each of the segments of a bar which is in the air gap of a wafer is the seat of two electromotive force components associated respectively with the two systems of compound currents; the assembly operates on the summation of these fm on all of the pancakes; thus for example, the parasitic polyphase component intended for the other rotor leads to zero summation on all the segments of each bar. If intermediate currents in the looping through the end rings can develop, they will cause losses. For this reason, the bars must be isolated from each other along their length here.
- FIG. 10 gives another alternative embodiment of an asynchronous cage adapted to the invention. It is presented as an example on the external part of the rotor which is shown in section. We find the general principle which has just been described with bars 24a electrically insulated along their length and electrically connected at their ends by short-circuit rings 23. We also find the non-magnetic spaces 25 between wafers intended for decoupling. The peculiarity comes from the fact that the conductive bars 24a appear to consist of a set of segments delimited by the borders between successive wafers; these segments are each essentially straight and parallel to the longitudinal axis, but comprise between them a successive angular offset which can contribute partially or completely to ensuring the required phase shift between wafers at this gap.
- connection which in principle take the form of arcs of a circle in the plane perpendicular to the longitudinal axis. These connections can be used as wedges in non-magnetic spaces.
- the bar segments can have an inclination relative to their reference position, and the principle aliasing between the segments can be greatly reduced, or even masked.
- This embodiment where the phase shift is carried out with the rotor allows free choice of the relative angular positioning between wafers of the claw systems, for example on criteria of minimizing the leakage permeances between wafers. In terms of phase shift, it is also possible to play on the order of the pancakes.
- Asynchronous cages can be produced by various methods: copper conductive bars can for example be attached and welded in situ to their end rings. It is also possible to immediately make a complete cage, for example made of cast aluminum, to which the elements of sectored magnetic circuits are brought. It is also possible, in the case of using iron powders, to consider pressing the magnetic material on the cage. The mechanical strength of these assemblies can be obtained by bonding, overmolding, shrinking solutions, etc.
- This arrangement is illustrated in principle in Figure 11. As before, it consists of a polyphase set of n wafers, with annular coils 6 installed in a fixed magnetic circuit and two independent rotors 3, 5.
- each wafer receives only a single winding supplied according to the principle of compound currents; a double polyphase system with ni and n2 phases is thus obtained on all of the windings.
- this stator no longer leads directly to a single air gap instead of two: it is now closed by a cylinder head and only a system of claws remains.
- the active parts of the two rotors are arranged concentrically opposite these claws.
- the intermediate rotor that is to say the one directly opposite the stator, is through flow: this means that, to a large extent, the magnetic flux for coupling to the stator passes right through it radially, so that it interacts with the second rotor.
- FIG. 11 represents an intermediate rotor linked to the power source, the other being linked to the movement output; a reverse choice is possible.
- the rotors are external to the stator, but could be internal to it.
- the angular phase shifts adapted to compound current control are operated: thus, the relative setting of the active parts of the rotor 3 and of the stator claw system will be 2 ⁇ ( ⁇ .nl), if p is the number pairs of claws and neither the number of phases of the system associated with rotor 3; similarly, the timing relative of the active parts of the rotor 5 and of the stator claw system will be 2 ⁇ / ( ⁇ .n2), n2 now being the number of phases of the system associated with the rotor 5.
- stator-rotor 3 and stator-rotor 5 interaction pairs independently by the compound current control: the first current system with neither phases is set to the angular position electric and therefore the electric pulsation of the rotor 3: its amplitude and its phase allow the adjustment of the associated torque level.
- the second current system with n2 phases is set to the electrical angular position and therefore the electrical pulsation of the rotor 5; its amplitude and phase allow the adjustment of the associated torque level.
- ni and n2 for example among those in the figure
- FIG. 12 provides an illustration with asynchronous cage rotors.
- the pulsations of each current system correspond to p. ⁇ l. (l-gl) and p, ⁇ 2. (L + g2) respectively, gl and g2 being the slip required to establish the desired couples, as it is known in the control of asynchronous machines.
- the reference 31 designates an intermediate rotor with flow through and with an asynchronous cage. Its conductive bars 24 extending parallel to the axis of the rotor. The structure of this intermediate rotor is identical to that shown in FIG. 9.
- the reference 32 designates the external rotor with an asynchronous cage.
- the structure of the rotor 32 is identical to that shown in FIG. 10.
- NB depending on the shape of the claws and the space between them, it may or may not be desirable to give these bars an inclination relative to their reference direction, as is often done in the usual asynchronous machines for smoothing the powerful phenomena associated with the notching of the stator.
- the ends of the bars are electrically connected to each other on each side of the rotor by a conductive ring, according to the usual principle of asynchronous cages.
- Electrical continuity between the segments of a bar is ensured at the borders between wafers by connections which in principle take the form of arcs of a circle in the plane perpendicular to the longitudinal axis.
- the bar segments may have an inclination relative to their reference position, and the aliasing in principle between the segments may be greatly reduced, or even masked.
- the ends of the bars are electrically connected to each other on each side of the rotor by a conductive ring, according to the usual principle of asynchronous cages.
- the polyphase stators of the two electric machines comprise annular windings and are integrated in adjacent spaces; the distribution of the alternating flow in the air gap takes place by claw systems or zero sequence teeth.
- the rotors can be of different types (with magnets, asynchronous, etc.), and in particular with variable reluctance with double salience with transverse looping of the flux to the rotor.
- the annular windings of the two stators are pooled and supplied by a compound current control with a single inverter. The arrangement can then be with an intermediate stator with "traversing flux” or else with an intermediate rotor with "traversing flux”.
