Abstract
Stator () of an electric motor, in particular an electric motor for refrigerant compressors, the stator () comprising a coil, the coil comprising windings (), where at least one of the windings () comprises two wires () of different materials that are electrically connected in parallel, where the windings () are disposed at least in sections in mounting slots () of the stator (). It is provided according to the invention that the mounting slots () each have a mounting cross section () with a mounting cross-sectional area A, within which the windings () are disposed and cover a total cross-sectional area A, where a degree of filling F is given as the ratio of the total cross-sectional area to the mounting cross-sectional areaand where the coil is designed so that for a given power and/or given efficiency of the electric motor, the degree of filling F is greater in at least one mounting slot () than the highest degree of filling F in the case of an alternative coil that has exactly as many windings, but which windings consist of wires of only one material.
