Abstract

At least two winding modules nested hollow-cylindrically one inside the other and extending around a common winding axis, wherein said winding modules are spaced radially apart from one another within at least one hollow-cylindrical cooling channel arranged therebetween by means of insulation strips, wherein the insulation strips have a cross-sectional form which avoid a surface profile radially with respect to the winding axis, the insulation strips including one of a fiber-reinforced epoxy, polyester resin, or from an unreinforced thermoplastic material.
