The invention relates to a stator (1) of an electric motor, in particular of an electric motor for a refrigerant compressor, said stator (1) comprising a coil, said coil comprising windings (3), wherein at least one of the windings (3) comprises two wires (4, 5) made of different materials and connected electrically parallel, wherein the windings (3) are arranged at least in sections in receptacle grooves (2) of the stator (1). According to the invention, the receptacle grooves (2) each have a receptacle cross-section (8) having a receptacle cross-section area AAQ , within which the windings (3) are arranged and cover a total cross-section area Atot , wherein a filling degree F results, as a ratio of the total cross-section area to the receptacle cross-section area F = Atot /AAQ and wherein the coil is designed such that, in case of a specified power and/or a specified degree of efficiency of the electric motor, the filling degree F in at least one receptacle groove (2) is greater than the highest filling degree F in an alternative coil, which has exactly as many windings, but said windings consist of wires of only one material. |
