Description
Dispositi de reglage pour moteur electrique ä collecteur 0n sait que la tension du reseau electrique n'a pas ete choisie ä la meine valeur dans tous les pays. Les tensions les plus courantes sont de 110 volts, 125 volts et 220 volts. Les appareils munis d'un moteur electrique doivent donc etre adaptes ä la tension utilisee dans 1e pays auquel ils sont destines. Adjusting device for electric motor with commutator It is known that the voltage of the electric network has not been chosen at the same value in all countries. The most common voltages are 110 volts, 125 volts and 220 volts. Appliances fitted with an electric motor must therefore be adapted to the voltage used in the country for which they are intended.
Dans certains cas, les constructeurs ont prevu des moteurs bivoltage qui peuvent etre adaptes ä une tension de Fordre de 110 volts ou de 220 volts par simple com- mutation de Fenroulement d'excitation. Lorsque 1e mo- teur electrique est uruni d'un dispositif de reglage elec- tronique, celui-ci doit etre etabli en tenant compte de la tension d'alimentation du moteur, ce qui complique encore la täche du fabricant. Il est donc avantageux de pouvoir utiliser un meine type de dispositif de reglage sans avoir ä tenir compte de la tension pour laquelle 1e moteur electrique est prevu. In some cases, manufacturers have provided dual voltage motors which can be adapted to a voltage of the order of 110 volts or 220 volts by simply switching the excitation winding. When the electric motor is fitted with an electronic adjustment device, the latter must be established taking into account the supply voltage of the motor, which further complicates the task of the manufacturer. It is therefore advantageous to be able to use the same type of adjustment device without having to take account of the voltage for which the electric motor is intended.
Le brevet principal a pour objet un dispositif de reglage pour moteur electrique ä collecteur alimente en courant alternatif par 1'intermediaire d'au moins une diode contrölee, dopt 1'instant d'allumage est determine par un eircuit de commande comprenant au moins un condensateur Branche en serie avee une resistance variable, ce dispositif etant caraeterise en ce que 1'elec- trode d'allumage de la diode contrölee est reliee au point commun de Liaison de la resistance variable et du con- densateur, au moins une diode et une resistance supple- mentaires etant branchees de fagon ä obtenir des cons- tantes de temps differentes pendant les deux demi-alter- nances de la tension d'alimentation. The main patent relates to an adjustment device for an electric motor with a commutator supplied with alternating current via at least one controlled diode, the moment of ignition of which is determined by a control circuit comprising at least one capacitor. Connected in series with a variable resistor, this device being characterized in that the ignition electrode of the controlled diode is connected to the common point of connection of the variable resistor and of the capacitor, at least one diode and one additional resistors being connected so as to obtain different time constants during the two half-cycles of the supply voltage.
La presente invention a pour but de permettre d'uti- liser un seul type de dispositif de reglage convenant aux deux tensions prevues pour un moteur bivoltage et d'ob- tenir pratiquement la meine courbe de vitesse en fonc- tion de la valeur donnee ä la resistance variable pour Tune et 1'autre desdites tensions. 13ien entendu, les meines avantages sont obtenus Jans 1e cas oü 1e meine dispositif de reglage est destine ä etre monte Sur des moteurs pre- vus uniquement pour une tension de 110 volts ou pour une tension de 220 volts. The object of the present invention is to make it possible to use a single type of adjustment device suitable for the two voltages provided for a dual-voltage motor and to obtain practically the same speed curve as a function of the value given to the variable resistance for one and the other of said voltages. Of course, the same advantages are obtained in the case where the same adjustment device is intended to be mounted on motors provided only for a voltage of 110 volts or for a voltage of 220 volts.
Ce but est atteint, selon la presente invention, gräce au fait qu'au moins un des composants ä caract6ris- tique non lineaire est Branche en serie avec 1e conden- sateur. This object is achieved, according to the present invention, thanks to the fact that at least one of the components having a non-linear characteristic is connected in series with the capacitor.
La figure unique du dessin annexe represente, ä titre d'exemple, 1e Schema dune forme d'execution du dispositif de reglage selon Finvention. The single figure of the appended drawing represents, by way of example, the diagram of one form of execution of the adjustment device according to the invention.
Le Schema represente constitue une modification du Schema selon la fig. 1 du brevet principal. Un moteur M ä collecteur et dont 1'enroulement d'excitation E est Branche en Serie est alimente par une source de courant alternatif reliee aux Bornes a et b. Le courant d'alimen- tation du moteur est contröle par un thyristor T, appele aussi di-ode contrölee, dont 1'electrode de commande est reble par 1'intermediaire dune diode Zener D2 ä une Borne de condensateur Cl dont Fautre Borne est reliee ä une Borne du moteur. La Borne b est reliee au condensateur Cl par l'intermediaire dune resistance R1 en Serie avec une resistance R3 qui est ä caract6ris- tique non lineaire du type VDR. Le condensateur Cl est egalement reue ä la Borne b par une diode Dl et par une resistance variable R2 en serie avec une r6sis- tance fixe R4. The diagram represented constitutes a modification of the diagram according to fig. 1 of the main patent. A motor M with a commutator and whose excitation winding E is connected in series is supplied by an alternating current source connected to terminals a and b. The motor supply current is controlled by a thyristor T, also called a controlled diode, the control electrode of which is connected by means of a Zener diode D2 to a terminal of capacitor Cl, the other terminal of which is connected. ä a Motor terminal. Terminal b is connected to capacitor Cl via a resistor R1 in series with a resistor R3 which has a non-linear characteristic of the VDR type. Capacitor C1 is also received at Terminal b by a diode D1 and by a variable resistor R2 in series with a fixed resistor R4.
Un interrupteur S permet de court-circuiter 1e thyristor T et la diode Dl pour alimenter 1e moteur sous sa ten- sion nominale. A switch S makes it possible to short-circuit the thyristor T and the diode D1 to supply the motor at its nominal voltage.
Lorsque la Borne b est positive par rapport ä la Borne a, la diode Dl est conductrice et 1e condensateur C1 est charge par les resistances Rl et R3 en parallele avec R2 et R4. En principe, 1'interrupteur S est ouvert sauf lorsqu'on veut faire tourner 1e moteur M ä la vi- tesse la plus grande. When Terminal b is positive with respect to Terminal a, diode D1 conducts and capacitor C1 is charged by resistors R1 and R3 in parallel with R2 and R4. In principle, the switch S is open except when it is desired to make the motor M run at the highest speed.
Des que 1e potentiel du condensateur Cl atteint la tension de Zener de la diode D2, celle-ci devient conduc- As soon as the potential of capacitor C1 reaches the Zener voltage of diode D2, the latter becomes conductive.
trice et les courants traversant les resistances R1, R2, R3 et R4 sont appliques ä 1'electrode de commande du thyristor T qui devient ainsi conducteur. A cet instant, les resistances susmentionnees viennent se mettre en parallele avec 1e condensateur Cl, un courant de decharge s'etablit jusqu'ä la fin de 1'alternance positive de la Borne b, instant oü 1e thyristor devient non conducteur. Ce courant de decharge est independant de la tension du secteur. Les variations importantes de rette demiere en- gendrent donc une variation de 1'angle d'allumage du thyristor. trice and the currents crossing the resistors R1, R2, R3 and R4 are applied to the control electrode of the thyristor T which thus becomes conductive. At this instant, the aforementioned resistances come to be placed in parallel with the capacitor Cl, a discharge current is established until the end of the positive alternation of Terminal b, instant when the thyristor becomes non-conductive. This discharge current is independent of the mains voltage. Significant variations in the last edge therefore generate a variation in the firing angle of the thyristor.
Il est bien evident que le condensateur Cl atteindra plus ou moins rapidement le potentiel de Zener de la diode D2 suivant la valeur choisie pour la resistance variable R2. La manoeuvre de rette resistance permet donc de regler 1'angle d'allumage du thyristor T pour les alternances pendant lesquelles la Borne b est positive par rapport ä la Borne a. La resistance R4 Limite 1e courant de charge de Cl lorsque R2 = 0. A 1'appa- rition de 1'alternance suivante, la Borne a devient positive par rapport ä la Borne b, et la diode Dl, ainsi que le thyristor T passent ä leur etat non conducteur. Il con- vient de noter que la diode Dl est en Serie avec 1e thy- ristor T, de Sorte quelle protege celui-ci contre les sur- tensions eventuelles. It is quite obvious that capacitor Cl will more or less quickly reach the Zener potential of diode D2 depending on the value chosen for variable resistor R2. This resistance maneuver therefore makes it possible to adjust the ignition angle of the thyristor T for the half-waves during which Terminal b is positive with respect to Terminal a. Resistor R4 limits the charging current of Cl when R2 = 0. On the appearance of the next half-wave, Terminal a becomes positive with respect to Terminal b, and diode D1, as well as thyristor T, switches to to their non-conductive state. It should be noted that the diode D1 is in series with the thyristor T, so that it protects the latter against possible overvoltages.
Par Suite de 1'inversion de polarite, 1e courant dans le condensateur Cl s'inverse. Le condensateur West relie ä la Borne b que par les resistances R1 et R3 dont la valeur est choisie assez Brande pour maintenir 1e courant de decharge du condensateur ä un niveau trop bas pour qu'une inversion genante de la polarite aux Bornes du condensateur Cl puisse se produire. Si 1e dis- positif de reglage represente a ete prevu pour fonctionner avec un moteur de 110 volts, la valeur des resistances R2 et R4 a ete choisie pour qu'en position ouverte de 1'interrupteur S, 1'instant d'allumage du thyristor T donne 1e courant minimum necessaire pour 1'entraine- ment du moteur M ä hasse vitesse. Si 1e meine dispo- sitif ne presentait pas la resistance non lineaire R3 et si ce dispositif etait utilise saus modi- fication pour etre Branche sur un reseau ä 220 volts, 1e moteur M etant bien entendu dans ce ras un moteur universel ä collecteur prevu pour 220 volts, il est clair que la tension d'allumage de la diode Zener serait atteinte par 1e condensateur Cl dans un temps plus court, 1'influence des resistances R1, R3 et R2, R4 sur la decharge de Cl lorsque 1e thyristor conduit etant plus petite. Il en resulterait une avance de 1'allumage du thyristor T, de sorte qu'on obtiendrait, pour 1e moteur M, une vitesse sensiblement plus rapide dans 1e ras du moteur ä 220 volts que dans 1e ras du moteur ä 110 volts. As a result of the polarity reversal, the current in capacitor C1 reverses. Capacitor West is connected to Terminal b only by resistors R1 and R3, the value of which is chosen high enough to maintain the capacitor discharge current at a level too low for a disturbing reversal of the polarity at the terminals of capacitor C1 to be possible. occur. If the adjustment device represented has been designed to operate with a 110 volt motor, the value of resistors R2 and R4 has been chosen so that in the open position of switch S, the instant of ignition of the thyristor T gives the minimum current required to drive the motor M at high speed. If the same device did not present the nonlinear resistance R3 and if this device was used without modification to be connected to a 220 volt network, the motor M being of course in this ras a universal motor with collector provided for 220 volts, it is clear that the ignition voltage of the Zener diode would be reached by the capacitor Cl in a shorter time, the influence of the resistors R1, R3 and R2, R4 on the discharge of Cl when the thyristor conducts being smaller. This would result in an advance of the ignition of the thyristor T, so that one would obtain, for the motor M, a substantially faster speed in the flush of the motor at 220 volts than in the flush of the motor at 110 volts.
La resistance R3 presente une caracteristique non lineaire symetrique du type VDR, ce qui revient ä dire que la valeur de rette resistance diminue lorsque 1e courant qui la traverse augmente. Gräce ä rette non- linearite, 1'ensemble des resistances R1 et R3 prUente une plus Brande conductibilite lorsque 1e dispositif est Branche Sur un reseau ä 220 volts. 1I en resulte que 1e courant de decharge du condensateur Cl par res r6sis- tances R1 et R3 pendant que la Borne a est positive augmente plus fortement que 1e courant de charge par 1'ensemble de R1 et R3 en parallele avec F.2 et 114. Cette augmentation du courant de decharge a pour effet de retarder 1'instant d'allumage du condensateur, ce qui permet de compenser 1'avance de cet allumage qui est due ä 1'utilisation du dispositif dans un reseau ä tension plus elevee. Resistor R3 has a symmetrical nonlinear characteristic of the VDR type, which amounts to saying that the value of this resistance decreases when the current flowing through it increases. Thanks to this non-linearity, the set of resistors R1 and R3 exhibits greater conductivity when the device is connected to a 220 volt network. As a result, the discharging current of capacitor C1 through resistors R1 and R3 while Terminal a is positive increases more than the charging current through R1 and R3 together in parallel with F.2 and 114 This increase in the discharge current has the effect of delaying the instant of ignition of the capacitor, which makes it possible to compensate for the advance of this ignition which is due to the use of the device in a higher voltage network.
Par un rapport convenable entre R1 et R3 et compte tenu des caracteristiques du moteur IVi, il est possible de realiser un dispositif de reglage dopt chacune des po- sitions de la resistance variable R2 permet d'obtenir une meine vitesse du moteur M, que celui-ci sofft un moteur du type 110 volts et connecte ä un reseau de 110 volts, qu'il sofft du type ä 220 volts et Branche dans un reseau ä 220 volts ou qu'il sofft du type bivoltage Branche res- pectivement Sur un reseau correspondant ä ses deux tensions nominales. By a suitable ratio between R1 and R3 and taking into account the characteristics of the motor IVi, it is possible to produce an adjustment device adopting each of the positions of the variable resistor R2 makes it possible to obtain the same speed of the motor M, as that whether it is a 110 volt type motor and connected to a 110 volt network, whether it is a 220 volt type and plugs into a 220 volt network or whether it is a dual voltage type plugs into a network respectively corresponding to its two nominal voltages.
Il est clair que ce resultat pourrait etre obtenu de fa@on differente et qu'au lieu de brancher en Serie avec la resistance R1 une resistance R3 ä caracteristique du genre VDR, an pourrait obtenir un meine effet de com- pensation en branchant en Serie avec R2 une resistance non lineaire dont 1e coefficient de resistance augmente en meine temps que 1e courant. It is clear that this result could be obtained in a different way and that instead of connecting in series with resistance R1 a resistance R3 with a characteristic of the VDR type, one could obtain the same compensation effect by connecting in series with R2 a nonlinear resistor whose resistance coefficient increases at the same time as the current.
La resistance non lineaire R3 pourrait etre aussi rem- plac6e par deux diodes Zener en Serie et de polarite opposee. The non-linear resistor R3 could also be replaced by two Zener diodes in series and of opposite polarity.
