| 摘要 |
<p>The invention concerns an armature commutator (24) of an electric rotary machine, in the form of a drum comprising an outer cylindrical surface whereon are arranged axially oriented longitudinal conductor segments (30) comprising each a friction track (34) for brush or carbon contacts, and each of which is extended by a connecting end (38) to at least one wire (16) of a winding, in the form of a longitudinally open hook, the hook comprising a base section (40) located in the front extension of the conductor segment (30), a connecting section (42) in the form of a bend and a free end section (44) extending rearwards above the base section (40). The invention is characterised in that the inner surface (50) of the connecting end comprises at least a projecting zone (48) which co-operates with the periphery of a section of the wire (16) housed in the hook. The invention also concerns an armature and an electric rotary machine comprising such a commutator.</p> |
