Definitions
- Known devices of this type operate in such a way that the plate moves in translation or in rotation around an axis of rotation situated outside the zone of the airfoils of the electromagnets and thus assimilable to a translational movement of the plate.
- the present invention results from the observation that the greater the mechanical performance of a known electromagnetic control device, the more bulky this device.
- It relates to a device having at least first and second gaps of variable thickness to be closed by the plate during positioning of the mechanical element in at least one position, the plate being rotated so that the The axis of rotation of the plate passes between the first and second air gaps.
- the second position of the mechanical element is such that the gaps are open or said large air gaps.
- a closed air gap is also called a low air gap.
- the two positions of the valve are controlled by the plate which oscillates angularly between two positions controlled by similar means.
- the permanent magnet although placed out of the magnetic circuit of the electromagnet, is traversed by the magnetic flux generated by
- the magnetic material included in the plate is advantageously a ferromagnetic material.
- the invention relates to a device for electromagnetic control of the opening and closing of a mechanical element, the positioning of the mechanical element in at least one position (open or closed) being obtained by the action of at least one electromagnet acting on a plate including a magnetic material and controlling the positioning of the mechanical element, this device comprising: at least a first and a second gap of variable thickness to be closed by the plate during the positioning the mechanical element in at least one position, the plate being mounted in rotation so that the axis of rotation of the plate passes between the first and second air gaps, and - at least one permanent magnet for biasing the device so as to maintain the plate in at least one position in the absence of current in the electromagnet, this permanent magnet not being traversed by the magnetic flux main electromagnet.
- Figure 10 shows a perspective view of an exemplary embodiment of the invention.
- the magnetic circuits and the magnetic fluxes are represented by a closed curve referenced for the sake of clarity by the same reference.
- the magnetic circuit is a circuit that can channel a magnetic flux.
- the arrow on such a closed curve indicates the direction of polarization magnetic flux.
- the magnetic fluxes are represented in the cutting plane of the plate.
- the symbols used are identical for all the figures.
- the double arrows represent the directions of the polarization fluxes in the permanent magnets and the directions of the induction fluxes created by these permanent magnets in the air gaps.
- the simple arrows represent the directions of the induction fluxes generated by the coils in the air gaps.
- the devices described preferably have a linear behavior and preferably operate without magnetic saturation to allow a high controllability of the device. Proper sizing of the different elements of the devices allow such behaviors.
- the coefficient ⁇ is classically of the order of 10 N / cm 2 , 160 at the most.
- This half period T / 2 is related to the operation of the engine. It is of the order of 3 ms.
- FIG. 3 shows a case of non-polarized device with four gaps where the two positions of the plate 33 are controlled by two electromagnets 30 and 36, respectively comprising a first and a second coil 31 and 37 and a first and second magnetic circuit 32 and 38
- Four air gaps 34a, 34b and 34c, 34d are therefore present in the two magnetic circuits 32 and 38 and intended to be closed alternately, two by two, depending on the position of the plate 33 and therefore the valve.
- This unpolarized configuration is in fact a double basic system similar to that described in Figure 1.
- the polarization is called series when the flux of a bias magnet is in series with the flow of the coil for performing the actuation of the device.
- the configurations shown in Figure 4 and Figure 5 are examples of such polarization. These examples have the advantage of being simple configurations of construction even if the magnetic circuits which carry the coils are rather complex, because crisscrossed.
- the magnets In the case of serial configurations, it is advantageous for the magnets to be as thin as possible in order to maintain a good efficiency of the ampere turns of the coils. Indeed the magnets constitute an additional gap for the amp turns generated by the coils. On the other hand, the magnets are subjected to demagnetizing fields which can be important when the fields of the coils are in opposition with their magnetization.
- the induction Bpc and Bpd is lower because the magnet 49b sees a relatively large air gap, but it is not zero.
- This induction generates a fairly weak force which slightly reduces the main attraction force generated by the magnet 49a.
- the use of rather thin magnets allows this force to be very reduced.
- the inductions Bba and Bbb in the air gaps 44a and 44b add (or retract in the direction of the current) to the induction due to the polarization.
- the magnetic flux generated by the current in the coil 41 may be in both gyratory directions and follows the same circuit 42 as the polarization magnetic flux.
- the coil 41 then sees an air gap equivalent to the thickness of the magnet 49a. The thickness of this magnet is therefore advantageously reduced to obtain a high efficiency of actuation by the coil 41.
- FIG. 6 representing a case of parallel polarization.
- the magnetic circuit 68 in which circulates the magnetic flux generated by the coil 67 of the electromagnet 66 when it is traversed by a current does not include a permanent polarization magnet. It is the same for the magnetic circuit 62 in which circulates the magnetic flux generated by a current in the coil 61.
- a single magnet has been shown in FIG. 6, but the system functions in the same way with a second magnet as for Figure 8.
- the stream of the coils can pass through a simple small air gap 98 devoid of magnet and crossed by the ampere turns in parallel with the gap which contains the magnets as shown in a dashed circle in Figure 9.
- This gap is shown in Figure 9, in parallel of the magnet 99a, but similar air gaps can be used in parallel magnets 89a, 89b and 99b. This allows the use of relatively large sections for permanent magnets. In addition, these magnets may not be subject to significant demagnetizing fields, which allows the use of low-end magnets and large section.
- the magnetic circuit of the so-called parallel series configurations of FIGS. 8 and 9 is quite simple, and it allows a great variety of embodiments.
- the magnetic flux can pass through two air gaps (84a and 84c) closed by the plate when it tilts to a position.
- This makes it possible to use air gaps seen by the relatively small coils, and thus to make the contribution of the coils more efficient than for series polarizations. It has therefore been shown that it is advantageous to use devices with a small magnet thickness to obtain a series behavior for small air gaps and parallel for large air gaps.
- the plate is located in the middle of the gaps for reasons of simplicity at the level of the variations of the forces on each side of the plate.
- any other position of the plate such as the latter is mounted in rotation about an axis located between the gaps is concerned by the invention.
- the two coils can also be powered simultaneously.
