  • mobile phones are equipped with batteries of a certain capacity, it is inevitable that the capacity of the batteries will be reduced as mobile phones tend to be smaller. As a result, when the battery is exhausted when trying to use it, the phenomenon of being unable to make a call increases. This can lead to unexpected disadvantages for those who operate with the convenience of mobile phones in mind.

Abstract

Ce générateur de puissance plat et de petite taille peut produire de l'énergie électrique à un niveau requis pour un ensemble téléphone portatif et peut être réduit à la dimension voulue pour cet ensemble. Ce générateur est pourvu d'un rotor plat à aimants portant plusieurs pôles magnétiques N et S disposés en alternance sur la surface périphérique intérieure du rotor, une armature de stator portant plusieurs pôles magnétiques entourés chacun d'enroulements d'armature sur la périphérie extérieure et placés sur l'intérieur du rotor, de façon que les pôles magnétiques du stator puissent faire face aux pôles magnétiques du rotor. On actionne manuellement ce générateur en imprimant une force d'entraînement rotationnelle au rotor.
