An armature for an electric d.c. machine, in particular a stator for a d.c. brushless motor, and a method for the manufacture thereof

The armature (1) comprises a ferromagnetic structure (2) made of stacked laminations (10) and including an annular portion (3) and a plurality of radial teeth (4) between which a corresponding plurality of slots (5) is defined, each tooth (4) carrying a respective winding (6). The ferromagnetic structure (2) is formed of a plurality of separate tooth members (4), each comprising a respective stack (12) of laminations (10) and having a root portion (12a), an intermediate shank portion (12b) carrying the respective winding (6), and a distal head portion (12c). The tooth members (4) arc mechanically interconnected and magnetically coupled with each other through respective mating formations (12f, 12g) of their root portions (12a), whereby the interconnected root portions (12a) of the tooth members (4) form the said annular portion (3) of the ferromagnetic structure (2).
