Abstract

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.
