Abstract
A prefabricated coil for placement on a tooth for a direct drive is orthocyclically wound from a wire of circular cross section. The coil includes two straight portions having an inner surface facing an interior of the coil and an outer surface opposite and parallel to the inner surface. A distance between the inner surface and the outer surface defines a thickness of the coil. Two coil overhangs connect the straight portions. A distance between the coil overhangs defines a height of the straight portions. The inner and outer surfaces of the straight portions have the height of the straight portions and a width of the straight portions. A sheet-like insulator covers the straight portions. The wire and the sheet-like insulator are bonded together such that the coil is self-supporting under the application of pressure and temperature. The sheet-like insulator has a joint region at the outer surface.
