Abstract

See full text

A method for manufacturing a plurality of generators, each intended to power supply an electronic circuit operating in a given power supply voltage range, includes a step of manufacturing coils distributed in N pluralities of coils, similar within the same plurality and different from one plurality to another, and a step of manufacturing a plurality of rotors which is carried out with tolerances limiting the cost of production. The plurality of rotors is classified into N classes of rotors which are associated respectively with the N pluralities of coils to form N pairs allowing the assembly of N groups of generators. The generators of each of the N groups of generators have magnetic coupling factors between their rotor and their stator which are located in a corresponding optimised value range, which is at least partially superimposed on the others of the N optimised value ranges relating to the N generator groups.
