The rotary electric actuator, to operate the harness cords at a Jacquard loom, has an armature (4b) as a stack of plates (20) where the stator has at least two stator units side by side following the rotary axis of the rotor. Each stator component has two zones to take a coil (4a) of electrically conductive wire (22). Some of the plates in each zone are matched with each other. The matched plates in each zone are formed by a single plate along the armature (4b) length. The matched plates, before assembly into the armature, are shaped with a central rupture bridge (20d) which can be turned partially round the wire coil. Each plate is extended at right angles to the bridge by a prong and at the side of it, and two prongs of neighboring plates are in the same direction at the other sides of their bridges. The prongs can be embedded into each other when the bridges have been broken. The plates of the stator units are assembled head to foot. A socket structure is shaped to accommodate the two stator components, together with the connections for the actuator electrical supply. An Independent claim is included for the production of each stator unit by winding on to an armature, and folding (F1, F2) each armature to bring their ends (20c) together and form a fitting to take the rotor through the mounting of the ends. Preferred Features: The armature is folded by rupture of the bridges, and the prongs are embedded by the alternating prongs of the rupture bridges. A molding stage, using an elastomer, holds the stators to the socket, with the electrical feeds to the stator assembly. |
