Abstract (en)
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. <IMAGE>
