The present invention pertains to the mechanical and electronic industry, and relates to a coil winding system for transformers and/or electric motors. Thus, the present invention relates to a coil winding system that comprises an element for rotating the needles and a headpiece (4) mounted in said element, the needle rotating element comprising a drive shaft (2a) designed for moving the headpiece (4) in translation and in rotation. The needle rotating element further comprises an electromagnetic element for rotating the headpiece (4) integrated in the drive shaft (2a). The use of the present system, in which an electromagnetic needle rotating element is fitted to the drive shaft (2a), avoids the mechanical coupling of the two motions, allowing the rotor to move freely both radially and linearly inside the magnetic field of the stator. This leads to greater flexibility and ease of automation, since the system has an angle of rotation that can be electronically programmed, rather than a mechanically fixed angle as in previous solutions; the system is also faster in that inertia is reduced in the absence of the mechanical coupling, more precise since the play between mechanical parts is eliminated, less prone to wear, eliminating the need for constant lubrication due to the absence of attrition and friction, is less costly and requires less maintenance. |
