Abrégé

An armature segment of an electrical machine includes a coil and a core section. A method of producing such a segment comprises the steps of tightly winding the coil, providing a compaction die having a cavity for shaping the tightly wound coil, introducing the tightly wound coil into the compaction die and compacting the coil therein so as to reduce the volume occupied by the coil, providing a compression-moulding die having a moulding cavity, positioning the compacted coil in the moulding cavity of the compression die, filling the moulding cavity with insulated ferromagnetic particles, and compressing the insulated ferromagnetic particles in the moulding cavity so as to form the armature segment as a single-piece unit including the core section and the compacted coil.
