摘要:
La montre comprend deux moteurs multipolaires coaxiaux, situés au centre, dont le rotor (4) de l'un est monté sur un arbre (13) qui porte une aiguille de secondes (17) et dont le rotor (5) de l'autre est monté sur le canon (12 b ) d'une chaussée (12) traversée par l'arbre (13). Le canon (12 b ) porte une aiguille de minutes (18). Le pignon (12) entraîne la roue (14) d'un mobile démultiplicateur dont le pignon (15) est en prise avec une roue (16) montée rotativement sur le canon (12 b ) et qui porte une aiguille d'heures (19). Les enroulements (8 et 9) des deux moteurs sont diamétralement opposés. L'entraînement des aiguilles de secondes (17) et de minutes (18) est direct en ce sens que ces aiguilles sont solidaires des rotors (4 et 5), respectivement, qui les entraînent.

Un générateur, destiné notamment aux dispositifs consommateurs de courant miniaturisés, comporte une roue rotorique (4) couplée à un axe mené et dotée de pôles magnétisés, un stator (5) possédant une pluralité d'enroulements destinés à produire une tension électrique, un dispositif d'entraînement (2, 33) servant à entraîner l'axe mené (3), ainsi qu'un dispositif de transmission possédant un corps élastique (34) assurant une transmission élastique entre ledit dispositif d'entraînement et ledit axe mené. Un dispositif interrupteur (37) sert à interrompre au moins sensiblement la transmission entre ledit dispositif d'entraînement et ledit axe mené en fonction de la tension de ressort dudit corps élastique. De préférence, le dispositif interrupteur comporte un certain nombre de ressorts à lames disposés autour d'un disque ou d'un embrayage de roue libre (37).

The electric supply voltage system is provided with an alternating current generator, an electrically chargeable accumulator, and a direct current generator. The alternating current generator is provided with a rotor with permanently magnetized poles and a stator which is provided with at least one electric winding for generating an alternating current when the rotor moves relative to the stator. The system further comprises an eccentric oscillatory weight for driving the rotor. The system is further provided with an accelerating transmission included between the oscillatory weight and the rotor, which accelerating transmission is provided with a resilient coupling, such that the oscillatory weight can move in advance of the rotor while the rotor can reside in one of the rest conditions. The accelerating transmission is provided with a first transmission which is included between the oscillatory weight and a point of application of the resilient coupling, and a second transmission which is included between a second point of application of the resilient coupling and the rotor.

Electro-mechanical timepiece, comprising a circuit for generating electric pulses that appear at suitable points of time, a stepper motor (1) controlled by said pulses and comprising a rotor (2) with permanently magnetic poles (8,9), a stator (3,4,5) and a coil (6), as well as a gear driven by the action of the step motor (1) for driving the clock hands, the stator (3, 4, 5) being constructed from two stator parts (3,4) situated on either side of the rotor (2) and a yoke (5), connecting these two parts (3, 4) and extending through said coil (6). The poles (8,9) are situated in a same cross section plane, perpendicular to the rotation axis of the rotor, and form a ring-shaped layer (14) which is thin in radial direction. According to a preferred embodiment the rotor (2) is at the radial inner side of the poles provided with an uninterrupted round-going ring-shaped portion (7) of soft-magnetic material.

A generator, for miniature power consuming devices in particular, comprises a rotor wheel (4), which is coupled to a driven shaft and which has magnetized poles, a stator (5) having a plurality of windings for providing an electric voltage, a driving means (2, 33) for driving the driven shaft (3), and a transmission means having a resilient body (34) for providing a resilient transmission between said driving means and said driven shaft. Interrupting means (37) are provided for at least substantially interrupting the transmission between said driving means and said driven shaft as a function of the spring tension of said resilient body. The interrupting means preferably comprise a number of leaf springs, arranged around a disc, or a free-wheel clutch (37).
