A method for producing an electrical coil device may include winding a strip conductor into a coil winding and subsequently dividing the coil winding into at least two partial coils by at least one cut through the coil winding, wherein the strip conductor remains connected as a doubly contiguous loop by existing remaining connections in the end regions of the strip conductor. An electric coil device is also disclosed, which includes at least two partial coils from a higher-level doubly contiguous strip conductor. The at least two partial coils may be produced by subsequent cutting of a coil winding wound by a single strip conductor.

Forming an electrical coil device by cutting a strip conductor winding into at least two partial coils

An electric coil apparatus has at least two subcoils from a superordinate doubly connected tape conductor. The coil apparatus has at least two conductor branches, each of the subcoils being wound from one of these conductor branches respectively. The conductor branches of the superordinate tape conductor have a superordinate first surface and a superordinate second surface facing away from this first surface. In a first subcoil, the first surface of the tape conductor faces a centerpoint of the first subcoil, and in a second subcoil, the second surface of the tape conductor faces a centerpoint of the second subcoil. Furthermore, in a manufacturing method of such a coil apparatus the two conductor branches are routed parallel to each other so as to dorm the subcoils.
