Abstract
The inventive coil comprises a coil body (1) on which an exciter winding (7) is arranged. A peripheral insulation winding (8) consisting of an insulating fiber is formed over the exciter winding, the individual windings of the insulating winding being bonded to each other in order to form a continuous insulation layer. The insulation winding can be made up of a mineral fiber impregnated with duromer resin or a thermoplastic fiber which has been melted on by subsequent heat treatment.
