Abstract
An electric motor is disclosed with an air-cored winding which is composed of a plurality of single coils made of wire, wherein the single coils overlap each other in an imbricated manner and the single coils are preformed to form an offset at least in the region of two opposite corners, so that half of the legs are located in a first plane and half of the legs are located in a second plane. A more inexpensive and more robust assembly of air-cored windings for electric motors can thereby be achieved.
