Abstract: 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.

Abstract: A needle winding machine, particularly for winding poles arranged inside a cylindrical surface, the machine comprising a main supporting structure that supports at least one spindle that is extended around an axis and is provided, at an axial end thereof, with a head that supports a wire guiding tube; the spindle can move on command parallel to its own axis and can rotate on command about its own axis with respect to the main supporting structure; the wire guiding tube can rotate on command, with respect to the remaining part of the spindle, about a rotation axis that is substantially perpendicular to the axis of the wire guiding tube and can move on command, with respect to the remaining part of the spindle, along a direction that is oriented radially with respect to the axis of the spindle.
