Apparatus and methods for winding supports for coils and single poles of cores of dynamo electric machines

A method for winding coils of at least one electrical wire on a coil support that is wound and assembled on a pole of a core of a dynamo electric machine, or a pole that is wound and assembled to form the core of a dynamo electric machine, the method comprising the steps of:

• dispensing the wire using a dispensing member configured to translate relative to an axis of rotation of the coil support to change a distance between the dispensing member and the axis of rotation, the wire dispensing member having a passage portion for the wire and an exit from where the wire reaches the coil support during winding of the coil, wherein during winding the wire that extends from the dispensing member to the coil support has an angular orientation with respect to the exit that remains constant, and wherein during winding the wire that extends from the dispensing member to the coil support is not inclined with respect to the exit;
• rotating the coil support with respect to the dispensing member for rotation around the axis of rotation to wind the wire onto the coil support;
• and
• pressing with pressing means on a portion of wire wound on the coil support, wherein the portion of wire on which a pressing occurs is located on the coil support that is immediately adjacent to a portion of wire that still has to be wound on the coil support.

Apparatus for winding coils of at least one electric wire on a coil support that is wound and assembled on a pole of a core of a dynamo electric machine, or a pole that is wound and assembled to form the core of the dynamo electric machine, the apparatus comprising:

• a wire dispensing member for dispensing the wire, the wire dispensing member configured to translate relative to an axis of rotation of the coil support to change a distance between the dispensing member and the axis of rotation, the wire dispensing member having a passage portion for the wire and an exit from where the wire reaches the coil support during winding, wherein during winding the wire that extends from the dispensing member to the coil support is not inclined with respect to the exit;
• an assembly for rotating the coil support with respect to the dispensing member for a rotation around the axis of rotation to wind the wire onto the coil support;
• and
• means for pressing on a wire portion wound on the coil support, wherein during winding the means for pressing presses on a portion of wire that is located on the coil support immediately adjacent to a portion of wire that still has to be wound on the coil support.
