Abstract: An insulation system for a stator of an electric motor, in particular for an electric motor of an electrical compressor, wherein the stator has multiple coil carriers which point radially inwards from a stator inner side and have inner flanges spaced apart on the head side, said inner flanges radially delimiting coils wound onto the coil carriers with electrical conductors, wherein the insulation system comprises insulator elements which are each held at their foot end by holding grooves formed on the stator inner side in the axial direction between axial end sides of the stator and are positioned pointing radially inwards between adjacent coils with their head ends between opposing flanks of adjacent inner flanges, wherein an electrically insulating substance is introduced in contact regions between the insulator elements and the holding grooves and/or between the insulator elements and the inner flanges of the coil carriers.
