Apparatus and method for winding poles of cores for electric dynamo machines

Method for winding coils (B) of wire conductor (W) around respective poles (10c) of a core (10) of a dynamo electric machine component;

• the coils (B) having turns (Sp,S), wherein a turn is formed of two opposite longitudinal stretches, each longitudinal stretch being deposited in a respective slot (10a,10b), and two stretches of the turn are each deposited adjacent a respective axial end (A) of the pole (10c);
• the method comprising the steps of:
• forming the wire turns of a coil (B) using a wire dispenser arm (11) rotating around the poles to dispense the wire (W);
• positioning and moving a first wire guide (32) during winding adjacent an axial end (A) of a pole (10c) being wound;
• positioning and moving a second wire guide (36) within a first slot (10a) adjacent to the pole (10c) being wound;
• positioning and moving a third wire guide (37) positioned within a second slot (10b) adjacent to the pole (10c) being wound;
• supporting the first wire guide (32) using a first support member (35);
• supporting the second wire guide (36) and the third wire guide (37) using a second support member (23);
• guiding the second wire guide (36) along a respective axis of the first slot (10a) using first guide means (38) supported by the second support member (23);
• guiding the third wire guide (37) along a respective axis of the second slot (10b) using second guide means (39) supported by the second support member (23);
• moving (18,26,50) the first support member (35) to move the first wire guide (32) along a movement axis (11′), the second wire guide (36) and the third wire guide (37) in a predetermined alignment with respect to each other and with the pole (10c) being wound, and moving the second wire guide (36) and the third wire guide (37) respectively along the first and the second guide means (38,39).
