In a rotating electrical machine a stator winding is formed of flexible cabl es (20, 22, 26) inserted in open stator in the stator core. The stator slots extend from a radially outermost yoke part of the stator core radially inwar ds towards the rotor, the stator slots being separated by teeth. The stator slo ts are shaped as double slots with shoulders (24, 28) arranged in the slot wall s in such a manner that each cable in the winding is secured between the previous cable in the stator slot and, seen from the slot opening, the next shoulder situated outside that particular cable. In a method for manufacturi ng such a winding the first cable (20) is inserted through the opening of the stator slot and pressed firmly into a cable slot arranged at the bottom of t he stator slot and designed to retain the cable when it has been pressed in, whereupon a second cable (22) is inserted through the opening of the stator slot and secured between this first cable and an opposing securing shoulder (24) in the wall of the slot, after which a third cable (26) is inserted through the opening in the stator slot and secured between said second cable (22) and a securing shoulder (28) in the slot wall opposite the second cable , and so on.
