Abstract

The invention relates to a method for producing a rotor and/or a stator of a dynamoelectric rotary machine by means of the following steps: —producing pre-formed coils from an integral electrically conductive material or pre-insulated or coated electrically conductive wires, —fixing spacers to the pre-formed coil at predefinable intervals, —inserting the pre-formed coil, which is provided with spacers, into slots in a laminated core of a stator or rotor, —making contact with the individual pre-formed coils to form groups of coils and forming a winding system of a rotor and/or stator in accordance with a predefined circuit plan, —insulating the pre-formed coils or the winding system in the slots by complete encapsulation, in particular by complete vacuum encapsulation.
