Abstract
The invention relates to an electrotechnical coil, to a method for producing same, and to an electromagnet or an electric machine comprising at least one such coil. The aim of the invention is to produce and use an electrotechnical coil for achieving an increased slot fill factor reliably and easily in a reproducible and economical manner. This is achieved in that the method according to the invention has the steps: step A: casting an electrotechnical coil with at least one winding which runs about a coil axis; and step B: shaping the coil, thereby changing the cross-section Q, Q' of the at least one winding, such that the centroid FS, FS′ of the cross-section Q, Q′ of the at least one winding is displaced at least partly in the radial direction R relative to the coil axis A.
