Cette construction a l'inconvénient de modifier l'enroulement de travail au moment de la commutation et par conséquent des tensions lead either with the auxiliary winding. This construction has the disadvantage of modifying the working winding at the time of switching and consequently of the voltages.

De cette façon, on évite les composantes transitoires pendant la commutation et on réduit en même temps la main start-up motors and are only coupled in parallel with some of the main windings when the motor has reached a determined speed of rotation. In this way, the transient components are avoided during the switching and at the same time the

L'invention va maintenant être décrite en se référant aux dessins annexes dans lesquels: la figure 1 représente un montage de moteur asynchrone monophasé connu; la figure 2 représente un montage de moteur asynchrone monophasé selon l'invention; et la figure 3 représente le couple en fonction de la The invention will now be described with reference to the accompanying drawings in which: FIG. 1 represents a known single-phase asynchronous motor assembly; FIG. 2 represents an assembly of a single-phase asynchronous motor according to the invention; and Figure 3 shows the torque as a function of the

Le montage du moteur asynchrone monophasé représenté sur la figure 1 comprend quelques enroulements principaux A1, A2, un condensateur C et un enroulement auxiliaire S. L'enroulement auxiliaire S est monté en parallèle avec un ou plusieurs des composants ci-dessus, la commutation étant effectuée grâce au commutateur 1 dans la phase de démarrage The assembly of the single-phase asynchronous motor shown in FIG. 1 comprises a few main windings A1, A2, a capacitor C and an auxiliary winding S. The auxiliary winding S is mounted in parallel with one or more of the above components, the switching being performed by switch 1 in the start-up phase

Le montage d'un moteur asynchrone monophasé représenté sur la figure 2 comprend des enroulements principaux Ai', A2', un enroulement auxiliaire S' monté en parallèle avec un ou plusieurs des enroulements principaux et un condensateur C' Selon l'invention, l'enroulement auxiliaire S' et le condensateur C' sont montés en parallèle avec un ou plusieurs des enroulements principaux A1', A2'. De cette façon, le condensateur sert à la fois de condensateur de démarrage et de condensateur de fonctionnement, de sorte que l'on obtient un rapport plus élevé entre le moment de démarrage et le moment de fonctionnement. Dès que le moteur tourne, le commutateur 1' permet de commuter le moteur en position de fonctionnement, conformément au schéma de la figure 2, avec environ la moitié du couple. La figure 3 illustre en outre certaines courbes des variations du moment D en fonction du nombre n de tours ou du glissement dans la position de démarrage et dans la position de fonctionnement, respectivement. En outre, le montage selon The mounting of a single-phase asynchronous motor shown in FIG. 2 comprises main windings Ai ', A2', an auxiliary winding S 'mounted in parallel with one or more of the main windings and a capacitor C' According to the invention, the auxiliary winding S 'and the capacitor C' are mounted in parallel with one or more of the main windings A1 ', A2'. In this way, the capacitor serves as both a start-up capacitor and an operating capacitor, so that a higher ratio between the start-up time and the operating time is obtained. As soon as the engine is running, the switch 1 'makes it possible to switch the engine to the operating position, in accordance with the diagram in FIG. 2, with approximately half of the torque. FIG. 3 also illustrates certain curves of the variations of the moment D as a function of the number n of turns or of the sliding in the starting position and in the operating position, respectively. In addition, mounting according to
l'invention permet une meilleure utilisation des matériaux. the invention allows better use of materials.

tation, et en ce que la tension aux bornes de l'enroulement auxiliaire et du condensateur est diminuée lorsque le moteur a atteint sa pleine vitesse de rotation, ce qui tation, and in that the voltage at the terminals of the auxiliary winding and of the capacitor is reduced when the motor has reached its full speed of rotation, which
apporte une réduction des pertes.reduces losses.
Le condensateur C' a une capacité coprise entre 50 The capacitor C 'has a capacity between 50
et 300 pF.and 300 pF.
Le moteur asynchrone est par exemple un moteur de 1 à cv et utilisable par exemple pour faire tourner une pompe ou un ventilateur. Le moteur asynchrone est de préférence alimenter par une tension secteur alternative de 220 V, dont la fréquence est de préférence égale à 50 Hz. The asynchronous motor is, for example, a 1 to hp motor and can be used, for example, to rotate a pump or a fan. The asynchronous motor is preferably supplied by an AC mains voltage of 220 V, the frequency of which is preferably equal to 50 Hz.
