Apparatus for winding and terminating dynamo electric machine cores

Apparatus for winding and terminating coils wound with at least one electric wire (W) on a core (20) of a dynamo electric machine;

• the core having a longitudinal axis (20′);
• the apparatus comprising:
• a wire dispenser (21);
• the dispenser having a tubular portion for passage of the wire and an exit from where the wire (W) reaches the core (20);
• means (106) for translating the dispenser (21) with respect to the core during winding or the termination of leads;
• support means (70) for supporting the core (20);
• means (82) for rotating the support means of the core around a rotation axis (20′);
• means (100) for feeding the wire W comprising a pulley wheel (30) where the wire is wound before entering the passage portion of the dispenser (21);
• a recovery device (34,35) of the wire that draws the wire returning from the pulley wheel (30).
• characterized in that the means for feeding the wire comprises:
• a device (33) for applying torque in two directions (RP1,RP2) on the pulley wheel (30) as a function of the position of the dispenser in the translation (TR1,TR2) and the position of the core in the rotation (RO1,RO2).

Apparatus for winding and termination of coils wound with at least one electric wire (W) on a core (11) of a dynamo electric machine;

• the core having a longitudinal axis (11′) and a groove (120) at an end (D) of the core for receiving at least a wire on a termination path that extends around the longitudinal axis;
• said apparatus comprising:
• a wire dispenser (20);
• the dispenser having a holding structure (105) for passage of the wire and an wire exit from where the wire reaches the core (20);
• means (106) for translating the dispenser with respect to the core (20) during winding or the termination of the leads;
• wherein the means for translating translates the holding structure (105) along the core for positioning the wire exit adjacent the end (D) of the core where the groove (120) is located;
• support means (70) for supporting the core (20);
• means (82) for rotating the support means (70) for rotating the core (20) around a rotation axis (20′) for winding the core;
• characterized in that it further comprises:
• a wire deflector (85)
• support means (87) for the wire deflector (85) positioned adjacent the end (D) of the core where the groove (120) is located;
• the deflector intercepting and aligning the wire with the groove (120);
