The stator for electrical machines has stator slots that are open radially inward, at least some of which contain coils made from round wire and have side walls ( 10, 12 ) of equal length that each extend parallel to their center radial plane. To attain an especially high fill factor, the entrances ( 16 ) of the stator slots have a width, measured transversely to their center radial plane, that is slightly greater than the diameter d of the round wire ( 18 ). A further condition is that the width of the stator slots, measured between the parallel side walls ( 10, 12 ), amounts to (1+cos 30°)d, and the radially outer slot wall ( 14 ) forms angles of 60° and 120°, respectively, with each of the two side walls ( 10, 12 ).
