Abstract

A winding device for producing a field coil including a double-layer multiple-circuit winding for an electric motor includes a drive. The drive is configured to operate upon a winding mandrel with multiple lamellas arranged to be swung radially outwardly and inwardly by the drive in order to produce the double-layer multiple-circuit winding as a plurality of winding stacks that are arranged in separate slots and electrically connected in series, in parallel or both. At least two axially-separated winding stacks can be produced at the same time by the drive.
