NORMAL WINDING METHOD OF CONCENTRATED WINDING STATOR CORE

PROBLEM TO BE SOLVED: To tightly and normally wind wires fed from nozzles to a bobbin over the whole wound layer. SOLUTION: In this concentrated winding stator core, a coil is concentratedly wound to one slot by winding the wires 2 fed from the nozzles 11, 12 to the bobbin 3. In a normal winding method of the stator core, the nozzles 11, 12 are moved to the axial direction of the bobbin accompanied by the winding of the wires 2 to the bobbin 3, and even if the number of the wound layers of the wires 2 in the bobbin 3 is increased, the nozzles 11, 12 are axially moved in timing that a supply angle θs formed by the wires 2 to be fed and external peripheral faces (Pf1, Pf2, Pg1 and Pg2) of the bobbin 3 reaches a certain value ("0°" for example). Here, a face inclination angle θi at which the external peripheral face of the bobbin 3 forming the supply angle θs between the wires 2 is directed to a vertical direction is changed at each wound layer of the wires 2 in timing that the nozzles 11, 12 are moved to the axial direction of the bobbin.
