A process for forming the stack of metallic laminations for the stator of an electric motor and the stack of metallic laminations, from a plurality of overlapped metallic laminations (11), which are annular, mutually concentric and each provided with a plurality of orifices (14) axially aligned with respective orifices of the other metallic laminations (11), in order to define axial housings (15) along the height of the lamination stack (10), said process comprising the steps of: a- molding, in each axial housing (15), a respective insert (20) in a non-conductive material, occupying the whole volume of said axial housing (15); and b- hardening each insert (20) molded inside the respective axial housing (15), in order to lock said metallic laminations (10) against rotational and mutually relative displacements parallel and transversal in relation to the longitudinal axis of the lamination stack (10).
