A coil module for an electric machine, comprising: a first coil disc with a first coil carrier made of an electrically insulating material and at least one winding embedded in the first coil carrier and made of an electrically conductive material; a second coil disc with a second coil carrier made of an electrically insulating material and at least one winding embedded in the second coil carrier and made of an electrically conductive material; wherein the coil discs are arranged one behind the other in an axial direction of the electric machine; wherein the first coil disc and the second coil disc are configured and attached to each other such that a substantially annular cooling channel for a coolant is formed in the axial direction between the first coil disc and the second coil disc ; characterized in that the first coil disc comprises a first ceramic delimitation ; the second coil disc comprises a second ceramic delimitation ; each of the first ceramic delimitation and the second ceramic delimitation at least partially forms an inner wall of the substantially annular cooling channel ; the first coil carrier and/orthe second coil carrier comprise/comprises a substantially annular recess on a side facing the second and/or first coil disc in the axial direction, so that the recess is enclosed within the two coil discs and thus forms the cooling channel ; and the first ceramic delimitation and/or the second ceramic delimitation are/is provided in the form of a substantially annular ceramic disc arranged in the substantially annular recess on the first coil carrier and/or the second coil carrier. a first coil disc with a first coil carrier made of an electrically insulating material and at least one winding embedded in the first coil carrier and made of an electrically conductive material; a second coil disc with a second coil carrier made of an electrically insulating material and at least one winding embedded in the second coil carrier and made of an electrically conductive material; wherein the coil discs are arranged one behind the other in an axial direction of the electric machine; wherein the first coil disc and the second coil disc are configured and attached to each other such that a substantially annular cooling channel for a coolant is formed in the axial direction between the first coil disc and the second coil disc ; characterized in that the first coil disc comprises a first ceramic delimitation ; the second coil disc comprises a second ceramic delimitation ; each of the first ceramic delimitation and the second ceramic delimitation at least partially forms an inner wall of the substantially annular cooling channel ; the first coil carrier and/orthe second coil carrier comprise/comprises a substantially annular recess on a side facing the second and/or first coil disc in the axial direction, so that the recess is enclosed within the two coil discs and thus forms the cooling channel ; and the first ceramic delimitation and/or the second ceramic delimitation are/is provided in the form of a substantially annular ceramic disc arranged in the substantially annular recess on the first coil carrier and/or the second coil carrier. <EOS>
