Selon une définition générale de l'invention, l'organe de commande loge un moteur pas à pas, de type hybride, comprenant un rotor dont l'arbre de rotation correspond à celui de l'organe de commande et sur la circonférence duquel sont disposées des dents de polarités alternativement différentes et magnétisées par un aimant permanent, et un stator comprenant au moins des premier à quatrième pôles magnétiques disposés autour du rotor et possédant chacun des dents, au moins une première bobine enroulée dans le même sens autour des premier et troisième pôles opposés et une seconde bobine enroulée dans le même sens autour des second et quatrième pôles opposés, l'agencement des dents du stator par rapport à celui des dents du rotor permettant la génération inductive dans les première et seconde bobines de deux trains d'impulsions en fonction de la rotation du rotor, et les moyens de traitement étant reliés à l'une des bornes des première et seconde bobines pour recevoir et traiter ces deux trains d'impulsions et en déduire lesdites grandeurs électriques.According to a general definition of the invention, the control houses a stepper motor, hybrid type, comprising a rotor whose rotation shaft corresponds to that of the control member and on the circumference of which are arranged teeth of alternately different polarities and magnetized by a permanent magnet, and a stator comprising at least first to fourth magnetic poles arranged around the rotor and each having teeth, at least one first coil wound in the same direction around the first and third opposite poles and a second wound coil in the same direction around the second and fourth opposite poles, the arrangement of the stator teeth relative to that of the rotor teeth for inductive generation in first and second coils of two pulse trains in depending on the rotation of the rotor, and the processing means being connected to one of the terminals of the first and second coils to receive and process these two pulse trains and deduce therefrom said electrical quantities.
Selon un mode particulier de réalisation de l'invention, la distance angulaire entre deux dents successives du rotor est différente de la distance angulaire entre deux dents successives du stator, le pas du moteur étant proportionnel à ladite différence.According to a particular embodiment of the invention, the angular distance between two successive teeth of the rotor is different from the angular distance between two successive teeth of the stator, the motor pitch being proportional to said difference.
En pratique, le moteur pas à pas comprend un nombre élevé de pas d'une valeur de quelques degrés. In practice, the stepper motor includes a high number of not worth a few degrees.
Par exemple, le pas du moteur pas à pas est de 1,8°.For example, the step of the stepper motor is 1.8 °.
Le Demandeur s'est également posé le problème de fournir un organe de commande rotatif qui procure un effet tactile lors notamment du changement de l'affichage du paramètre de sélection du titre.The Applicant also raised the problem of providing a rotary control element which provides a tactile effect during including changing the display of the parameter title selection.
Elle trouve également une solution à ce problème en utilisant astucieusement des effets inductifs du moteur pas à pas.She also finds a solution to this problem by using cleverly inductive effects of the stepper motor.
Ainsi, selon un autre aspect de l'invention, les moyens de traitement sont propres à activer lesdites première et seconde bobines pour freiner ou bloquer inductivement la rotation de l'organe de commande en fonction du paramètre affiché sur les moyens d'affichage ou en réponse à une condition prédéterminée.Thus, according to another aspect of the invention, the means of processing are suitable for activating said first and second coils to inductively brake or block the rotation of the control unit according to the parameter displayed on the display means or in response to a predetermined condition.
Un tel dispositif a l'avantage d'utiliser pour le freinage inductif de l'organe de commande les mêmes bobines que celles utilisées pour la détection de la rotation de l'organe de commande. Toutefois, il a l'inconvénient de réclamer une électronique de commande du freinage à impédance interne élevée pour ne pas influencer la lecture des impulsions sur les bobines.Such a device has the advantage of using for braking inductive of the control member the same coils as those used for the detection of the rotation of the ordered. However, it has the disadvantage of claiming a brake control electronics with internal impedance high so as not to influence the reading of the pulses on the coils.
Une solution à ce problème consiste selon l'invention à équiper en outre le stator d'une troisième bobine fortement couplée avec la première bobine et enroulée dans le même sens que la première bobine autour des premier et troisième pôles magnétiques et d'une quatrième bobine fortement couplée avec la deuxième bobine et enroulée dans le même sens que la deuxième bobine autour des second et quatrième pôles magnétiques et d'activer lesdites troisième et quatrième bobines pour freiner ou bloquer inductivement la rotation de l'organe de commande en fonction du paramètre affiché sur les moyens d'affichage ou en réponse à une condition prédéterminée.A solution to this problem is according to the invention to additionally equip the stator with a third coil strongly coupled with the first coil and wound in the same direction that the first coil around the first and third poles magnetic and a fourth coil strongly coupled with the second coil and wound in the same direction as the second coil around the second and fourth magnetic poles and activate said third and fourth coils to inductively brake or block the rotation of the organ of command according to the parameter displayed on the means display or in response to a predetermined condition.
Avantageusement, les moyens de traitement sont aptes à activer les première et seconde bobines ou les troisième et quatrième bobines selon une intensité et une durée choisies en fonction du paramètre affiché sur les moyens d'affichage ou en réponse à une condition prédéterminée.Advantageously, the processing means are able to activate the first and second coils or the third and fourth coil according to a chosen intensity and duration according to the parameter displayed on the display means or in response to a predetermined condition.

Sur la figure 1, on a représenté la façade avant FAC d'un distributeur de titres de transport ou analogue en échange d'un paiement. D'une manière connue, le distributeur comprend un écran ECR destiné à afficher au moins un paramètre relatif à la sélection du titre. Un organe de commande à rotation libre ORG est disposé en dessous de l'écran. Cet organe de commande est de forme cylindrique ou ovoïde. Une partie de la face externe du cylindre (sensiblement la moitié) affleure la surface de la face avant du distributeur tandis que l'autre partie de la face externe du cylindre est logée à l'intérieur de la façade avant du distributeur.In Figure 1, there is shown the front facade FAC of a distributor of transport tickets or the like in exchange a payment. In a known manner, the distributor comprises an ECR screen intended to display at least one relative parameter when selecting the title. A rotary control member free ORG is located below the screen. This organ of command is cylindrical or ovoid in shape. A part of the outer face of the cylinder (substantially half) is flush with the surface of the front face of the dispenser while the other part of the external face of the cylinder is housed inside front panel of the dispenser.
La façade avant du distributeur est complétée par des moyens de validation VAL et ANN (boutons à touches) de la commande de sélection d'affichage obtenus par l'entraínement par un usager de l'organe de commande à rotation libre.The front of the dispenser is completed by means VAL and ANN validation (buttons with keys) of the order display selection obtained by training by a user of the freely rotating control member.
Dans le cas de la distribution d'un titre en échange d'un paiement, le distributeur de titres comprend en outre des moyens de saisie de paiement PAI, par exemple du type paiement électronique, comprenant un clavier CLA et un lecteur de carte de paiement électronique LEC.In the case of the distribution of a security in exchange for a payment, the securities distributor also includes PAI payment entry means, for example of the type electronic payment, including a CLA keyboard and a LEC electronic payment card reader.
Des moyens de délivrance DEL d'un titre en réponse à la validation parachèvent la façade avant du distributeur.DEL delivery means of a title in response to the validation complete the front of the dispenser.
En référence à la figure 2, l'organe de commande ORG est de forme ovoïde. L'axe de rotation horizontal de l'organe de commande AX est parallèle au plus grand côté de l'organe de commande. L'organe de commande est à rotation libre entre deux fourches ou similaires FOU1 et FOU2 solidaires du châssis de la façade avant du distributeur à l'aide de moyens de fixation FIX1 et FIX2 de type connu.Referring to Figure 2, the ORG control unit is ovoid shape. The horizontal axis of rotation of the AX command is parallel to the longest side of the ordered. The control member is freely rotatable between two forks or the like FOU1 and FOU2 secured to the chassis of the front panel of the distributor using means fixing FIX1 and FIX2 of known type.
En référence à la figure 3, un moteur pas à pas MOT est logé dans l'organe de commande qui est constitué de deux coquilles COQ1 et COQ2 emboítables l'une dans l'autre.Referring to Figure 3, a MOT stepper motor is housed in the control member which consists of two shells COQ1 and COQ2 nestable one inside the other.
Par exemple, les coquilles sont constituées d'un alliage d'aluminium traité par oxydation anodique.For example, the shells are made of an alloy aluminum treated by anodic oxidation.
Le moteur pas à pas est raccordé à des moyens de traitement (non représentés) par des fils de raccordement FI.The stepper motor is connected to processing means (not shown) by FI connection wires.
En référence à la figure 4, le moteur pas à pas comprend un rotor (non représenté) dont l'arbre de rotation correspond à l'axe de rotation AX de l'organe de commande. Le moteur pas à pas MOT est composé d'une carcasse de forme parallélépipédique, solidaire de l'axe de rotation AX à l'aide d'une bague BAG en forme de U qui enserre totalement le boítier contenant le moteur pas à pas. Des moyens de type roulement et circlips ROU1 et ROU2 complètent les moyens de guidage en rotation libre du moteur pas à pas.Referring to Figure 4, the stepper motor includes a rotor (not shown) whose rotation shaft corresponds to the axis of rotation AX of the control member. Motor not MOT step consists of a parallelepiped-shaped carcass, secured to the axis of rotation AX using a ring U-shaped BAG that completely encloses the housing containing the stepper motor. Bearing and circlip means ROU1 and ROU2 complete the means of guiding in rotation free of the stepper motor.
Le moteur pas à pas est de type hybride, c'est-à-dire que le rotor ROT est à aimant permanent d'une part, et le couple rotor/stator présente une structure susceptible d'introduire une variation de réluctance d'autre part.The stepper motor is hybrid type, that is to say that the ROT rotor is permanent magnet on the one hand, and the torque rotor / stator has a structure capable of introducing a change in reluctance on the other hand.
Par exemple, le moteur pas à pas est celui vendu par la société MINEBEA (société japonaise) sous la référence 14PM-M201-T2 à six fils (figure 6) ou à quatre fils (figure 5).For example, the stepper motor is the one sold by the MINEBEA company (Japanese company) under the reference 14 PM-M201-T2 six-wire (Figure 6) or four-wire (Figure 5).
Le Demandeur s'est aperçu que ce moteur pas à pas hybride est capable de fournir des grandeurs électriques qui correspondent au sens de rotation et au déplacement angulaire de l'organe de commande contenant ce moteur pas à pas.The Applicant has noticed that this hybrid stepper motor is capable of supplying electrical quantities which correspond in the direction of rotation and the angular displacement of the control member containing this stepping motor.
En référence à la figure 5, le moteur pas à pas à 4 fils comprend un rotor ROT sur la circonférence duquel sont disposées des dents de polarités alternativement différentes DR et magnétisées par un aimant permanent inclus dans le rotor.Referring to Figure 5, the 4-wire stepper motor includes a ROT rotor on the circumference of which are arranged teeth of alternately different polarities DR and magnetized by a permanent magnet included in the rotor.
Le stator STA comprend au moins des premier à quatrième pôles magnétiques PM1 à PM4 disposés autour du rotor et possédant chacun des dents DS.The STA stator includes at least first to fourth poles magnetic PM1 to PM4 arranged around the rotor and having each of the DS teeth.
Une première bobine BA est enroulée dans le même sens autour des premier et troisième pôles opposés PM1 et PM3.A first BA coil is wound in the same direction around first and third opposite poles PM1 and PM3.
Une seconde bobine BB est enroulée dans le même sens autour des second et quatrième pôles opposés PM2 et PM4.A second coil BB is wound in the same direction around second and fourth opposite poles PM2 and PM4.
Une borne EA1 de la bobine BA est reliée à la masse et l'autre borne EA2 de la bobine BA est reliée à un amplifica teur de mise en forme suivi d'un détecteur de crêtes CT1 propre à délivrer des impulsions logiques TR1 synchrones avec le signal analogique présent à la borne EA2.A terminal EA1 of the coil BA is connected to ground and the other terminal EA2 of the coil BA is connected to an amplifier shaping device followed by a CT1 peak detector suitable for delivering synchronous TR1 logic pulses with the analog signal present at terminal EA2.
De même, une borne EB1 de la bobine BB est reliée à la masse et l'autre borne EB2 de la bobine BB est reliée à un amplificateur de mise en forme suivi d'un détecteur de crêtes CT2 propre à délivrer des impulsions logiques TR2 synchrones avec le signal analogique présent à la borne EB2.Similarly, a terminal EB1 of the coil BB is connected to ground and the other terminal EB2 of the coil BB is connected to an amplifier shaping followed by a CT2 peak detector suitable for delivering synchronous TR2 logic pulses with the analog signal present at terminal EB2.
L'avantage de tels circuits de mise en forme et de détection CT1 et CT2 est de rendre la génération des impulsions logiques TR1 et TR2 indépendantes de la vitesse de rotation du rotor tout en conservant le synchronisme des impulsions par rapport aux pas du moteur.The advantage of such shaping and detection circuits CT1 and CT2 is to make the generation of pulses TR1 and TR2 logic independent of the rotation speed of the rotor while maintaining the synchronism of the pulses relative to the engine pitch.
C'est l'agencement des dents DS du stator par rapport à celui des dents du rotor DR qui permet ici la génération inductive dans les bobines BA et BB des deux trains d'impulsions TR1 et TR2 en fonction de la rotation du rotor.This is the arrangement of the DS stator teeth relative to that teeth of the DR rotor which allows here the inductive generation in the coils BA and BB of the two pulse trains TR1 and TR2 depending on the rotation of the rotor.
Des moyens de traitement UT, de type microprocesseur, sont reliés aux circuits CT1 et CT2 pour traiter les deux trains d'impulsions TR1 et TR2 et en déduire le sens de rotation de l'organe de commande, son déplacement angulaire, et donc sa vitesse de rotation.Processing means UT, of microprocessor type, are connected to circuits CT1 and CT2 to process the two trains of pulses TR1 and TR2 and deduce the direction of rotation of the control member, its angular displacement, and therefore its rotation speed.
A partir de ces trains d'impulsions, les moyens de traitement UT sont ainsi propres à sélectionner l'affichage d'un paramètre à l'aide des grandeurs électriques fournies par le moteur pas à pas.From these pulse trains, the processing means UT are thus able to select the display of a parameter using the electrical quantities supplied by the step-by-step engine.
En pratique, la distance angulaire entre deux dents successives DR du rotor est différente de la distance angulaire entre deux dents successives DS du stator, le pas du moteur est ainsi proportionnel à cette différence.In practice, the angular distance between two successive teeth DR of the rotor is different from the angular distance between two successive DS stator teeth, the motor pitch is thus proportional to this difference.
Le choix de cette différence permet de définir un nombre élevé de pas d'une valeur de quelques degrés. The choice of this difference makes it possible to define a number high of steps worth a few degrees.
Par exemple, le pas du moteur pas à pas est de 1,8°.For example, the step of the stepper motor is 1.8 °.
De façon surprenante, le Demandeur a observé que ce moteur pas à pas peut en outre conférer un effet tactile à l'organe de commande.Surprisingly, the Applicant has observed that this engine step by step can also give a tactile effect to the organ control.
Pour cela, les moyens de traitement UT sont propres à activer lesdites première et seconde bobines BA et BB pour freiner ou bloquer inductivement la rotation de l'organe de commande en fonction du paramètre affiché sur les moyens d'affichage ou en réponse à une condition prédéterminée.For this, the UT processing means are able to activate said first and second coils BA and BB for braking or inductively block the rotation of the control member by depending on the parameter displayed on the display means or in response to a predetermined condition.
Pour l'activation des bobines BA et BB, les moyens de traitement UT délivrent à travers un circuit de commande CT3 un signal de courant continu, de 0 à 12 Volts par exemple, aux bornes EA2 et EB2 des bobines BA et BB.For the activation of the coils BA and BB, the means of UT processing deliver through a CT3 control circuit a DC signal, from 0 to 12 Volts for example, at terminals EA2 and EB2 of the coils BA and BB.
Avantageusement, le circuit de commande CT3 du freinage est à impédance interne élevée IM1 et IM2 pour ne pas influencer la lecture des impulsions sur les bobines BA et BB.Advantageously, the braking control circuit CT3 is with high internal impedance IM1 and IM2 so as not to influence reading the pulses on the coils BA and BB.
Le moteur pas à pas décrit en référence à la figure 5 est de type bipolaire dans la mesure où les bobines BA et BB sont parcourues par des courants dans les deux sens.The stepping motor described with reference to FIG. 5 is of bipolar type insofar as the coils BA and BB are crossed by currents in both directions.
En variante (figure 6), le moteur pas à pas est de type unipolaire dans lequel les bobines sont parcourues de courants dans un seul sens.As a variant (FIG. 6), the stepping motor is of the type unipolar in which the coils are traversed by currents in one direction.
Le moteur pas à pas unipolaire est ici à 6 fils. Son rotor ROT est identique à celui décrit en référence à la figure 5. Son stator est différent de celui décrit en référence à la figure 5 dans la mesure où en outre des bobines BA et BB agencées de façon identique à la figure 5, il comprend maintenant une troisième bobine BC fortement couplée avec la première bobine BA et enroulée dans le même sens que la première bobine BA autour des premier et troisième pôles magnétiques PM1 et PM3 et une quatrième bobine BD fortement couplée avec la deuxième bobine BB et enroulée dans le même sens que la deuxième bobine BB autour des second et quatrième pôles magnétiques PM2 et PM4.The unipolar stepper motor is here 6-wire. Its rotor ROT is identical to that described with reference to Figure 5. Its stator is different from that described with reference to the Figure 5 insofar as further coils BA and BB arranged identically to FIG. 5, it comprises now a third BC coil strongly coupled with the first BA coil and wound in the same direction as the first BA coil around the first and third poles magnetic PM1 and PM3 and a fourth BD coil strongly coupled with the second BB coil and wound in the same sense that the second BB coil around the second and fourth PM2 and PM4 magnetic poles.
Les bobines BA et BB ne sont plus activées par les moyens de traitement. Au contraire, le circuit de commande CT3 (sans impédance interne élevée) active maintenant les troisième et quatrième bobines BC et BD pour freiner ou bloquer inductivement la rotation de l'organe de commande ORG en fonction du paramètre affiché sur les moyens d'affichage ou en réponse à une condition prédéterminée.The coils BA and BB are no longer activated by the means of treatment. On the contrary, the control circuit CT3 (without high internal impedance) now activates the third and fourth coils BC and BD to inductively brake or block the rotation of the ORG control member according to the parameter displayed on the display means or in response to a predetermined condition.
Pour l'activation des bobines BC et BD, les moyens de traitement UT délivrent à travers le circuit de commande CT3 un signal de courant continu, de 0 à 12 Volts par exemple, aux bornes EC1 et ED1 des bobines BC et BD. Les bornes EC2 et ED2 des bobines BC et BD sont à la masse.For the activation of the BC and BD coils, the means of UT processing deliver through the control circuit CT3 a DC signal, from 0 to 12 Volts for example, at terminals EC1 and ED1 of the coils BC and BD. EC2 and ED2 of the coils BC and BD are grounded.
Grâce à l'activation commandée des bobines BA et BB (moteur bipolaire) ou BC et BD (moteur unipolaire), l'usager ressent sur l'organe de commande ORG un effet tactile qui peut être fonction du changement de la rubrique affichée et sélectionnée.Thanks to the controlled activation of the BA and BB coils (motor bipolar) or BC and BD (unipolar motor), the user feels on the ORG control unit a tactile effect which can be depending on the change of the item displayed and selected.
Il est à remarquer que cet effet tactile est totalement différent des dispositifs classiques tels que ceux connus sous le terme "souris" par le fait que le changement de rubrique provoqué notamment par la rotation de l'organe de commande peut produire un freinage dudit organe de commande ou un durcissement de la rotation dudit organe de commande.It should be noted that this tactile effect is completely different from conventional devices such as those known under the term "mouse" by the fact that the change in rubric caused in particular by the rotation of the organ of control can produce a braking of said control member or a hardening of the rotation of said control member.
Il est à remarquer que l'effet de freinage peut être constant, ou bien dépendant de certaines circonstances telles que la rubrique sélectionnée, ou l'absence d'action de l'utilisateur pendant une temporisation prédéterminée, ou encore la vitesse instantanée imprimée à l'organe de commande par l'utilisateur.It should be noted that the braking effect can be constant, or depending on certain circumstances such that the selected rubric, or the absence of action of the user for a predetermined time delay, or again the instantaneous speed printed on the control unit by the user.
Lorsque le freinage est dépendant de la rubrique sélectionnée, c'est le micro-ordinateur (moyens de traitement) gérant l'écran qui va commander l'intensité du freinage ainsi que sa durée en déterminant le signal de commande issu du circuit CT3.When braking is dependent on the selected item, it is the microcomputer (means of treatment) managing the screen which will control the intensity of the braking as well as its duration by determining the control signal from the circuit CT3.
Il est à remarquer que cette programmation permet d'éviter des choix erronés à l'usager en empêchant un mouvement involontaire de l'organe de commande qui pourrait déclencher une mauvaise sélection.It should be noted that this programming makes it possible to avoid wrong choices to the user by preventing movement involuntary from the control unit which could trigger wrong selection.
En pratique, lorsque le freinage est constant, l'usager ressent des "crans" inductifs offrant une certaine résistance à la rotation de l'organe de commande ORG.In practice, when braking is constant, the user feels inductive "notches" offering some resistance to the rotation of the ORG control member.
