A process for assembling a rotor of a variable-reluctance synchronous motor, characterised in that it comprises the steps of: i. preparing a plurality of discs having a through-cavity for each polar sector for housing at least a magnet; ii. positioning the discs in sequence along an axis of rotation for forming the rotor, so that the through-cavities are aligned to one another; iii. preparing magnets having an identical depth that is smaller than the depth of the rotor, and a frontal section that is identical to or smaller than the area of the cavity; iv. calculating the number of magnets to be inserted, for each polar sector, in a sequence so as to occupy only part of the total depth of the rotor as a function of the performances to be obtained; v. inserting the calculated number of magnets in a series of cavities aligned for each polar sector. The invention also relates to a rotor of a variable-reluctance synchronous motor assembled using the process set out above.
