The subject of the invention is more particularly an electromagnetic machine element, notably forming a stator or rotor, of new design. STATE OF THE ART In the field of electromagnetism, and particularly rotating machines, it is customary to use a stator comprising a plurality of coils each formed of a winding of turns in which a current is induced when the rotor associated with the stator and provided with magnets is rotated. The current generated is then a function of the coils used and the magnets used. The winding of the coils is made along an axis substantially perpendicular to a polar face of a rotor magnet. The coils do not maximize the interaction between a magnet and an associated coil. In addition, the winding of a coil is long to achieve.
    [0002] Connecting coils together in the context of a miniaturized stator is a tedious step in the context of the realization of the stator.

In addition, the element may comprise a stack of first tracks and a stack of second tracks, in particular extending in parallel directions. The invention also relates to an electromagnetic machine comprising at least a first element, in particular forming a stator, as described and a second element, in particular forming a rotor, provided with at least one magnetic element arranged so as to interact with the circuits of the first element during a relative rotational movement between the first and second elements.

According to an improvement, the machine may comprise two additional elements as described (including the tracks) radially surrounding the second element. The first element can be arranged so that it surrounds the second element. The machine may comprise an operating configuration in which the interaction of each magnetic element with at least one corresponding circuit of the first element allows generation of an electric current within said corresponding circuit. The machine may also include an operating configuration in which the circuits interact with at least one magnetic element to generate the relative rotational movement.

    [0006] DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION The rotor or stator element described below differs from the state of the art in that the coils are replaced by preferably flat crenellated tracks.
    [0007] As illustrated in FIGS. 1 and 2, the element 100 of electromagnetic machine, notably forming a stator or rotor, comprises at least a first electrically conductive track 101 in the form of an annular crenellated line so as to form a first plurality of electromagnetic circuits 102 capable of interacting with at least one magnetic element (not shown in FIGS. 1 and 2) of the electromagnetic machine. The element 100 further comprises at least a second electrically conductive track 103 arranged in the form of an annular crenellated line so as to form a second plurality of electromagnetic circuits 104 capable of interacting with at least one magnetic element of the electromagnetic machine. Said second track 103 is formed along said corresponding first track 101 and so that the circuits 104 of the second plurality of electromagnetic circuits are each disposed between two successive circuits 102 of the first plurality of electromagnetic circuits. It will be understood that the electromagnetic machine may comprise a plurality of magnetic elements. Each magnetic element is advantageously a dipolar magnet. That is to say a magnet comprising a north face and a south face, the field lines from the magnetic field of the magnet extending between the north and south poles of said magnet. By "electromagnetic circuit" is meant here a circuit behaving similarly to a turn of a coil in the context of its interaction with a magnetic element such as a dipole magnet. In fact, the circuit may be an armature in which electrical current is generated during the interaction with the magnetic element in the context of an electromagnetic machine operating as an electric power generator. Alternatively, the circuit can generate a magnetic field by voluntary application of an electric current passing through said circuit, when interacting with the magnetic element (s), the electromagnetic machine then operates as a motor. The electromagnetic machine is typically a rotating machine comprising a stator and a rotor. The electromagnetic machine may be of axial magnetic flux type (preferably at least a part of the dipolar magnetic elements is then arranged such that the axis passing through the two magnetic poles of each of the magnetic elements of said at least a part of the elements magnetic is parallel to an axis of rotation Al of the rotor of the electromagnetic machine and the tracks are arranged so as to face a pole of each magnetic element) and / or radial magnetic flux (preferably at least a portion of the magnetic elements dipoles is then located so that the axis passing through the two magnetic poles of each of the magnetic elements of said at least a portion of the magnetic elements is perpendicular to an axis of rotation Al of the rotor of the electromagnetic machine and the tracks are arranged so to face a pole of each element ma gnetic, alternatively the axes of the magnetic elements are similar to those of the axial magnetic flux but the tracks will be arranged so as to interact with the field lines between the two magnetic poles of each magnetic element). Advantageously, a pair of tracks comprising a first track and a second track is such that the first and second tracks are advantageously included in the same surface, preferably flat (for example in the plane of FIGS. 1 and 2) in order to exploit a axial magnetic flux, or cylindrical circular section (Figure 3) to exploit a radial magnetic flux. Preferably, the first and second tracks are shaped (in whole or in part) in the form of a band having a section, in a plane perpendicular to the elongation at least local of the strip, square or rectangular. The strip then has a main face, intended to face one or more magnetic elements, perpendicular to the direction directing the thickness of the strip. The transverse dimensions of the main face of the strip according to its elongation at least local, preferably at any point on the track concerned, are greater than the dimension defining the thickness of the strip.
    [0008] According to one particular embodiment, said at least one first track 101 comprises a plurality of electrically conductive transverse flanks 105 each extending between a first discontinuous lateral edge 106 (shaped along the dotted line li in FIG. 2) of the first 101 and a second discontinuous lateral edge 107 (shaped along the dotted line 12 in FIG. 2) of the first track 101. Each circuit 102 of the first plurality of electromagnetic circuits has a pair of adjacent transverse flanks 105 of the first track. 101. In addition, said at least one second track 103 comprises a plurality of electrically conductive transverse flanks 108 each extending between a third discontinuous lateral edge 109 (shaped along the dotted line 13 in FIG. 2) of the second track 103 and a fourth discontinuous lateral edge 110 (shaped along the dotted line 14 in FIG. the second track 103. Each circuit 104 of the second plurality of electromagnetic circuits has a pair of adjacent transverse flanks 108 of the second track 103. The discontinuous lateral edges are of course electrically conductive. It is understood that for each track, the band described above may have at least a local elongation for each discontinuous edge and each transverse flank. Preferably, at least the transverse flanks of the first and second tracks 101, 103 have a square or rectangular section in the form of a bar. This section shape maximizes the result of the interaction between a circuit and a magnetic element as it passes the circuit. The discontinuous lateral edges serving as a simple electrical conductor, their sections may be circular or square or rectangular. The first and second tracks 101, 103 are advantageously dimensioned such that each transverse flank is part of only one circuit. In other words, each circuit is separated from an adjacent circuit of the same track by a distance such that the magnetic element (s) can not be opposite two adjacent transverse flanks of two. separate circuits of the same track. In the opposite case, parasitic effects could reduce or nullify the efficiency of the electromagnetic machine. In the embodiment of Figures 1 to 3, the third discontinuous side edge 109 is located between the first and second discontinuous side edges 106 and 107, and the second discontinuous side edge 107 is located between the third and fourth discontinuous edges 109 and 110. According to a more detailed description, the first discontinuous lateral edge 106 is formed by a plurality of first electrically conductive segments 111 each connecting two transverse flanks 105 of the first track 101. The second discontinuous lateral edge 107 is formed by a plurality of second electrically conductive segments 112 each connecting two transverse flanks 105 of the first track 101. The third discontinuous lateral edge 109 is formed by a plurality of third electrically conductive segments 113 each connecting two transverse flanks 108 of the second track 103. The fourth edge discontinuous lateral 110 is formed by a plural Four first and third segments (111, 114) each have a length greater than that of each of the second and third segments (112, 113). More generally, this condition on the segment lengths allows adjacent transverse flanks of two adjacent circuits (i.e., directly connected by a first segment within the first track frame or by a fourth segment within the scope of the first segment. third track) not to form an electromagnetic circuit in the sense as defined above. In other words, the magnetic element can not interact with the transverse flanks of two adjacent circuits of the same track. Such an interaction would induce parasitic effects which reduce or cancel the efficiency of the electromagnetic machine. It is then understood that the annular crenellated line shape of the first track is conferred by the fact that for each transverse side of the first track, outside the transverse flanks of the ends of the first track, said transverse flank is connected on the one hand to a previous transverse flank by a first segment and secondly to a next transverse flank by a second segment. In this paragraph, the terms first track, first segment and second segment may be replaced respectively by second track, third segment and fourth segment. According to an implementation making it possible to make the most of the interaction between a rotor and a stator of the electromagnetic machine, the element comprises a stack of first tracks and a stack of second tracks. In particular, the stacks extend in parallel directions. Of course, to avoid any electrical short circuit, two tracks of the same stack are separated by an electrical insulator. In the context of an electromagnetic machine with axial magnetic flux, the stacks referred to above are in accordance with an axis of rotation of the rotor of the electromagnetic machine. In the context of an electromagnetic machine with radial magnetic flux, the stacks referred to above are in a direction perpendicular to an axis of rotation of the rotor of the electromagnetic machine. According to a first example, in the context of an electromagnetic machine with a radial magnetic flux, the first, second, third and fourth discontinuous lateral edges of a first track and a second associated track, are respectively included along each other. a first circle, a second circle, a third circle and a fourth circle. Said first, second, third and fourth circles are staggered along the same axis (forming in particular the axis of rotation of the rotor of the electromagnetic machine) and each have a radius of the same length. According to a second example, in the context of an electromagnetic machine with axial magnetic flux, the first, second, third and fourth discontinuous lateral edges of a first track and a second associated track, are respectively included along each other. a first circle, a second circle, a third circle and a fourth circle. Said first, second, third and fourth circles are included in the same plane and have the same center (in particular through which the axis of rotation of the rotor of the electromagnetic machine can pass). In this example, the radius of the first circle is greater than the radius of the third circle, itself greater than the radius of the second circle, itself greater than the radius of the fourth circle.
    [0009] Preferably, the element referred to above and comprising the first and second tracks is a stator of the electromagnetic machine.
    [0010] It will be understood that the invention also relates to an electromagnetic machine, as illustrated in FIGS. 4 and 5, comprising at least a first element 100, in particular forming a stator, as described above, and a second element 200, notably forming rotor, provided with at least one magnetic element 201 arranged to interact with the circuits (the circuits of the first plurality of circuits and the second plurality of electromagnetic circuits) of the first element 100 during a relative rotational movement between the first 100 and second 200 elements.
    [0011] By relative movement of rotation between the first and second elements 100, 200 is meant that there is an axis of rotation Al (visible in Figures 1, 3, 4 and 6) around which turns one of said first and second elements then that the other of said first and second elements remains fixed.
    [0012] In FIG. 5, the first element 100 comprises a stack of first tracks 101 and second tracks 103. Of course this is only a particular example, in fact a single first track 101 and a single second track 103 would have just as well could be used. In particular, the second element 200 may comprise at least one blade 202 as illustrated in FIG. 6. Therefore, the second element 200 forms a rotor of the electromagnetic machine and the first element 100 forms the stator of the electromagnetic machine. In the example of Figure 6, a plurality of blades 202 form a helix of the rotor. The propellers then extend between the axis of rotation Al of the rotor and an outer ring of the rotor carrying (or formed by) magnetic elements intended to interact with the circuits of the first element 100.
    [0013] It will be understood that in general, a turbine may comprise an electromagnetic machine as described and in which the second element 200 forms a rotor capable of being rotated by a fluid. The first element 100 then forms the stator of the electromagnetic machine. The turbine can then be a wind turbine (the fluid is then air) or a tidal turbine (the fluid is then a liquid). In particular, the second element 200 comprises a plurality of magnetic elements 201 advantageously as described above. Each magnetic element 201 is then arranged such that during the rotational movement it cooperates with the different circuits of the first element 100. In other words, according to one embodiment, each magnetic element 201 of the second element 200 is located so as to interact, during a complete revolution of one of the first or second elements 100, 200 about an associated axis of rotation (preferably a complete revolution of the second element 200 forming a rotor around its axis of rotation A1), with each circuit 102 of said at least one first track 101 and / or with each circuit 104 of said at least one second track 103. This ensures improved performance both in motor mode and generator mode of the electromagnetic machine. Preferably, the electromagnetic machine is such that each magnetic element 201 has, in particular parallel to the conductive tracks, a section such that at all times the relative rotational movement, said magnetic element 201 does not come opposite to at most two transverse sides of 'a couple of first and second tracks. In other words, during the relative rotational movement, a face of the magnetic element 201 defining a magnetic pole (north or south) of said magnetic element 201 passes next to each circuit of the first element (this being particularly true for each magnetic element ), and this face is dimensioned such that it never covers more than two transverse flanks 105, 108 of a pair of first and second tracks of the first element 100. When a magnetic element 201, or a face thereof last, comes opposite two side flanks during its rotation, it is understood that there is then an air gap along the axis of rotation (by the axis of rotation is meant parallel in the case of axial magnetic flux and perpendicular to case of radial magnetic flux) between said magnetic element and the two lateral flanks concerned. Thus, at any moment of the rotation of one of the magnetic elements, the two transverse flanks overlapped by said magnetic element belong to either the first track, the second track or the first and second tracks. Preferably, and always in the expectation of improving and / or maximizing the efficiency of the electromagnetic machine, during the relative rotation movement, said at least one magnetic element or each of the magnetic elements 201 never comes opposite the first , second, third and fourth discontinuous edges 106, 107, 109, 110. In other words, during the rotation of the rotor, the face of the magnetic element defining a magnetic pole (north or south) of said magnetic element 201 passes of each circuit of the first element (this being notably true for each magnetic element) without ever being opposite the discontinuous edges of the first and second tracks. In order to optimize the efficiency of the electromagnetic machine, the first (s) and second (s) tracks are adapted to the shape of the magnetic element (or magnetic elements), in particular to the dimensions of the face of the electromagnetic machine. magnetic element 201 (forming in particular a magnetic pole) facing the first element 100 during the rotational movement. In particular, the faces of all the magnetic elements arranged opposite the first element all have the same dimensions and are such that they respect the overlapping conditions as described. The shape of the face can then be square, rectangular, or trapezoidal. Thus, generally applicable to all that has been said above, the crenellated line shape does not imply the presence of transverse flanks parallel to each other. The aliasing of the line may be such that the slots have a shape tending towards the omega or the sinus. In particular, the transverse flanks can each extend along different radii of the same circle. According to one particular embodiment, the electromagnetic machine 20 has an overlapping configuration in which each circuit 102, 104 of the first plurality of electromagnetic circuits and the second plurality of electromagnetic circuits is opposite a corresponding magnetic element 201. In other words, there are as many magnetic elements as electromagnetic circuits contained in a pair of first and second tracks. This allows a maximized yield of the electromagnetic machine.
    [0014] Preferably, the magnetic elements 201 are arranged as illustrated in FIG. 4, that is to say so as to form a closed magnetic ring. In other words, the second element 200 may comprise a plurality of magnetic elements 201 staggered, in particular at regular intervals, along an annular line (forming for example a circle) centered on the axis of rotation A1. In particular, the second element 200 comprises a plurality of magnetic elements 201 arranged so as to present, opposite the first element 100, alternately a positive pole and a negative pole so that, during the relative rotational movement, when all the circuits of the first plurality of electromagnetic circuits are each interacting with positive poles, all the circuits of the second plurality of electromagnetic circuits are each interacting with negative poles. On the other hand, during the relative rotational movement, when all the circuits of the first plurality of electromagnetic circuits are each interacting with negative poles, all the circuits of the second plurality of electromagnetic circuits are each interacting with positive poles. As mentioned above, the electromagnetic machine can operate in motor or generator mode. Thus, the electromagnetic machine may comprise an operating configuration in which the interaction of each magnetic element 201 with at least one corresponding circuit of the first element 100 makes it possible to generate an electric current within said corresponding circuit. In addition, the electromagnetic machine can alternatively or in combination with the current generation mode, comprising an operating configuration in which the circuits (or at least one circuit) interact with at least one magnetic element 201 to generate the relative rotational movement.
    [0015] In order to optimize the efficiency by taking advantage of the two faces (in other words of the two opposite poles) of the magnetic elements, the electromagnetic machine may comprise, as illustrated schematically in FIG. 7, two first elements 100a, 100b, preferably identical, as described and arranged on either side of the second element 200 along an axis of rotation Al associated with the relative rotational movement. Preferably, here the element 200 forms the rotor and the elements 100a, 100b form two stators. Here, one of the first two elements is configured to face one of the magnetic poles of a magnetic element during the relative rotational movement while the other of the first two elements is configured to make opposite the other of the magnetic poles of said magnetic element. According to one possible improvement, the electromagnetic machine may also include, in addition to the first two elements 100a, 100b, a two additional elements 100c 100d (FIG. 7) each formed by another electromagnetic machine element as described (that is, i.e. having first and second tracks) and radially surrounding the second member 200. In this case, one of the additional members 100c is configured to interact with a first magnetic pole of an element. while the other of the additional elements is configured to interact with a second magnetic pole (opposite the first pole) of said magnetic element. The plane P1 is here perpendicular to the axis of rotation A1 of the rotor preferably formed by the element 200. This makes it possible in particular to use the field lines between the two opposite magnetic poles of the same magnetic element in order to generate further more electric power.
    [0016] According to a variant illustrated in FIG. 8, the first element 100 is arranged in such a way that it surrounds the second element 200. In other words, the first and second elements 100, 200 are included in the same plane P1 which is also the plane in particular rotation of the second element 200 that is to say perpendicular to the axis Al of rotation. In this case, each magnetic element has a magnetic pole facing said first element 100, and preferably the other magnetic pole is mounted on a steel ring 220. Generally applicable to all that has been said above, the first and second tracks can be formed of copper. Such tracks can easily be made by stamping, cutting. In addition, the final shape is directly obtained without long and tedious welding steps as in the context of the coils of the prior art.
    [0017] Preferably, and in a manner applicable to all that has been said above, each of the transverse flanks of the first and / or second tracks are straight, while the segments connecting two adjacent transverse flanks of the same track are curved. Moreover, in order to improve the efficiency of the electromagnetic machine, the skilled person can add to each element comprising the first and second crenellated tracks masses of magnetic material for concentrating the flows. For example, the element comprising the first and second crenellated tracks may comprise one or more magnetic cores arranged such that the first and second tracks are arranged between each magnetic element and all or part of the magnetic core or nuclei.
    [0018] In particular, the masses of magnetic material, or a part of these masses, can be arranged between each transverse flank of an electromagnetic circuit. The masses of magnetic material can be arranged in such a way as to reduce the residual magnetic torque.
