The circuit according to the invention is characterised in that a diode 6, 7 is mounted in the supply branch 1, 2 of each of the motors M1, M2, the mounting of the said diode 6, 7 being such that its direction of conduction is that of the supply to the associated motor M1, M2. Application to the central locking of motor vehicles.

Description

Circuit d'alimentation à sécurité d'arrêt pour moteurs électriques.Safety shutdown power circuit for electric motors.

L'invention concerne un circuit d'alimentation à sécurité d'arret pour moteurs électriques à courant continu tournant dans un seul sens et montés en parallèle.The invention relates to a stop-safe power supply circuit for direct current electric motors rotating in one direction and mounted in parallel.

Un tel montage de moteurs a de nombreuses applications, par exemple le verrouillage centralisé des véhicules automobiles.Such an assembly of engines has many applications, for example the central locking of motor vehicles.

Ce montage présente cependant l'inconvénient que, après ouverture de l'interrupteur commun d'alimentation, les moteurs ne s'arrêtent pas tous au même instant. Ceux qui continuent à tourner jouent, vis-à-vis de celui ou de ceux qui sont arrêtés antérieurement, le rôle de générateurs électriques et donnent ainsi à ces moteurs arrêtés une impulsion d'alimentation qui les fait tourner à nouveau.However, this arrangement has the disadvantage that, after opening the common power switch, the motors do not all stop at the same time. Those which continue to run play, vis-à-vis that or those which were stopped previously, the role of electric generators and thus give these stopped motors a supply pulse which makes them turn again.

Il est en conséquence pratiquement impossible d'obtenir une position d'arrêt unique et sure pour chaque moteur, ce qui est un inconvénient important dans de nombreuses applications,en particulier pour le verrouillage centralisé.It is therefore practically impossible to obtain a single and safe stop position for each motor, which is a major drawback in many applications, in particular for central locking.

La présente invention vise à pallier cet inconvénient.The present invention aims to overcome this drawback.

A cet effet, le circuit selon l'invention est caractérisé par le fait qu'une diode est montée dans la branche d'alimentation de chacun des moteurs, le montage de ladite diode étant tel que son sens de conduction soit celui de l'alimentation du moteur associé. Grâce à la diode associée à chaque moteur, le courant généré par un ou plusieurs moteurs non encore arrêtés ne peut alimenter un moteur arrêté, dont la position d'arrêt est en conséquence fixe.To this end, the circuit according to the invention is characterized in that a diode is mounted in the supply branch of each of the motors, the mounting of said diode being such that its direction of conduction is that of supply of the associated motor. Thanks to the diode associated with each motor, the current generated by one or more motors not yet stopped cannot supply a stopped motor, the stop position of which is consequently fixed.

L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dans lequel: - la figure 1 est un schéma d'une partie d'un circuit selon l'état de la technique, et - la figure 2 est un schéma correspondant à celui de la figure 1, pour un exemple de réalisation de l'invention.The invention will be clearly understood on reading the following description made with reference to the appended drawing in which: - Figure 1 is a diagram of part of a circuit according to the prior art, and - Figure 2 is a diagram corresponding to that of FIG. 1, for an exemplary embodiment of the invention.

Le circuit d'alimentation de moteurs M1, M2... représenté aux figures 1 et 2 est, dans l'exemple décrit, à commande par la masse, mais l'invention s'applique à tout autre mode de commande. Les moteurs M1, M2, etc. sont montés chacun sur une branche 1, 2, etc. reliée à une extrémité à un premier conducteur commun 3 lui-même relié au + et, à l'autre extrémité, à un second conducteur commun 4 relié à la masse par l'intermédiaire d'un interrupteur de commande 5.The motor supply circuit M1, M2 ... shown in Figures 1 and 2 is, in the example described, ground control, but the invention applies to any other control mode. Motors M1, M2, etc. are each mounted on a branch 1, 2, etc. connected at one end to a first common conductor 3 which is itself connected to the + and, at the other end, to a second common conductor 4 connected to ground via a control switch 5.

En cas de fonctionnement (interrupteur 5 fermé), le courant s'écoule du + vers le - en traversant chacun des moteurs
M1, M2, etc., qui est ainsi alimenté.In the event of operation (switch 5 closed), the current flows from + to - through each of the motors
M1, M2, etc., which is thus supplied.

Lorsqu'on ouvre l'interrupteur 5, les moteurs M1, 2' etc.When the switch 5 is opened, the motors M1, 2 'etc.

ne s'arrêtent pas tous simultanément. Par exemple, le moteur
M1 s'arrête le premier. Le moteur M2, qui continue à tourner, génère un courant électrique dans la bucle formée par la branche 2, le conducteur 4, la branche 1 et le conducteur 3.do not all stop simultaneously. For example, the engine
M1 stops first. The M2 motor, which continues to run, generates an electric current in the loop formed by branch 2, conductor 4, branch 1 and conductor 3.

Dans le cas du circuit connu représenté à la figure 1, ce courant généré circule effectivement dans la boucle et alimente le moteur M1, qui se remet à tourner. Sa position d'arrêt est donc modifiée.In the case of the known circuit represented in FIG. 1, this generated current effectively circulates in the loop and feeds the motor M1, which starts to rotate again. Its stop position is therefore modified.

L'invention prévoit de munir les branches 1 et 2 d'une diode 6,7 respectivement. Les diodes 6,7 sont montées de manière qu'elles conduisent dans le sens d'alimentation du moteur. The invention provides for providing branches 1 and 2 with a diode 6,7 respectively. The diodes 6,7 are mounted so that they lead in the direction of supply of the motor.

Lorsque l'interrupteur 5 est fermé, les diodes 6,7 n'ont aucune influence et les moteurs M1,M2, etc. sont alimentés normalement. A l'ouverture de l'interrupteur 5, le moteur
M1, par exemple, s'arrête le premier. Le courant induit par le moteur M2, qui continue à tourner, ne peut circuler dans la boucle 2-3-1-4 car il est arrêté par la diode 7 puisque le courant généré par le moteur M2 est inverse de son courant d'alimentation.When the switch 5 is closed, the diodes 6,7 have no influence and the motors M1, M2, etc. are powered normally. When switch 5 opens, the motor
M1, for example, stops first. The current induced by the M2 motor, which continues to rotate, cannot flow in the loop 2-3-1-4 because it is stopped by the diode 7 since the current generated by the M2 motor is opposite to its supply current .

Les diodes 6,7 peuvent être disposées entre les moteurs M1,
M2 respectivement et le conducteur commun 4 au lieu d'être, comme dans l'exemple représenté, entre les moteurs M1, M2 et le conducteur commun 3. The diodes 6,7 can be arranged between the motors M1,
M2 respectively and the common conductor 4 instead of being, as in the example shown, between the motors M1, M2 and the common conductor 3.
