Abstract

A general winding law for twisted coils is described in terms of analytic functions. On a toroidal surface given as ->chi = ->chi(phi,theta) (phi = toroidal coordinate, theta = poloidal coordinate) the current filaments phi = phi-kappa(theta) are represented in terms of sine functions. The paper includes several examples of classical stellarator and HELIAC configurations. By specifying a separate winding law for every single coil WVII-AS type configurations can also be modelled. The numerical code describing the central filament and the borderlines of the coils are given in the appendix.
