A winding method and machine for making multiple coils of conducting wires are described. Step A provides for prearranging a winding machine with a wire guiding device configured for guiding conducting wires in one or more bundles, a winding tool provided with two winding chambers in which the bundles of conducting wires are intended to be wound, a first spindle intended for rotating the winding tool, one or more storage satellites configured for storing a length of the bundles of conducting wires and a second spindle intended for rotating the storage satellites. The bundles of conducting wires are guided on the winding tool through the wire guiding device and are stored on the storage satellites. The first spindle rotates the winding tool on a rotation axis X-X to cause the winding of a first length of the bundles of conducting wires provided by the wire guiding device in a first winding chamber. The second spindle rotates the storage satellites about a rotation axis X-X and about the winding tool to cause the winding, in a second winding chamber, of second lengths of the bundles of conducting wires. The second lengths of the bundles are not withdrawn upstream from the wire guiding device, but downstream from the storage satellites.

METHOD AND WINDING MACHINE FOR MAKING AN ELECTRIC COMPONENT PROVIDED WITH A SPIRAL-SHAPED WINDING
A method and an automatic winding machine (20) for making an electric component (1) provided with a support (2) inside which at least one winding of a conducting wire (4) is housed, are described. Although the winding extends spirally, the conducting wire with which it is made is not twisted. It is provided to rotate the support on its axis while pushing the conducting wire into a slot (6', 6'') of the support by means of a pressure roller (53) which rolls on the slot. The pressure roller is guided by a wire guiding flange (49, 50) which controls its displacement so as the pressure roller intercepts and travels along the entire length of the slot. In an embodiment, the electric component is provided with a first winding (3') on a front side (2') of the support and with a second winding (3'') on the rear side (2'') of the support. The two windings are made with the same wire, which is overlapped on the perimeter edge of the support. The pressure roller is displaced from the front side to the rear side to perform the insertion of the wire into the slot of the second winding, by using a second wire guiding flange (50) as a guide.
A method and an apparatus for manufacturing a star yoke stator for electric motors with distributed winding, as well as a stator achieved with the method described, are described. A two-component stator is provided with a central star-shaped element provided with radial stator teeth and stator slots interposed between the teeth, and a yoke into which the star is inserted with the windings included in the stator slots. The assembly method provides for positioning the star on a rotating spindle and for inserting the linear portions of coils of wire, previously formed on a winding tool and preferably pressed and carburized, into the stator slots, so that to keep the arrangement of the wires in order. The windings are completed by alternating the movements of inserting coils into the stator slots and of rotating the star. The yoke can be coupled to the star in a final step, whenever the yoke is made in one piece, or can be constructed around the star by coupling sectors of the yoke as the windings are completed. An apparatus configured for implementing the method described is further described. The invention further concerns a stator directly obtained with the method described and an electric motor integrating the stator. Greater filling coefficient, greater efficiency, less leakage currents and reduced stator height are achieved.

WINDING METHOD AND MACHINE FOR WINDING CONDUCTING WIRE ON POLE PIECES OF ELECTRIC MOTO ROTORS
A method and an automatic winding machine for making high quality windings on pole pieces of rotors of electric motors with the direct in slot winding technique, thus overcoming the problem related to the elasticity of the pack of laminations that defines the body of the rotor, are described. While winding, the conducting wire is guided by means of a wire guiding cap movable in the rotor slots between which the pole piece to be wound at that moment extends. The body of the rotor is compacted by means of a pressing device internal to the wire guiding cap. The axial pressing of the body, performed parallel to the rotation axis Z of the rotor for preventing the umbrella effect, is thus formed thanks to a specific device integrated into the wire guiding cap, i.e. by exploiting the volume inside the wire guiding cap and providing the axial pressing device therein.
A method, a processing line and components of the processing line for making a stator for electric motors, and the resultant stator. The conducting wire is wound in coils having at least one straight portion which is inserted into a corresponding stator sector. The sector is thus deformed to move its teeth close to each other and to close the straight portion of the coil. Multiple stator sectors so made are assembled together to form a stator complete with windings. During the production of stator sectors, the coils and/or stator sectors are rototranslated to bring them to the final position they must take inside the finished stator. Measures are provided to maximize the filling factor, to minimize torque ripple phenomena, to minimize noise and the vibrations of the electric motor achieved with the stator, and to maximize its performance, under other equal conditions.
