Abstract

In a rotating electrical machine a stator winding is formed of flexible cables inserted in an open stator in the stator core. The stator slots extend from a radially outermost yoke part of the stator core radially inwards towards the rotor, the stator slots being separated by teeth. The stator slots are shaped as double slots with shoulders arranged in the slot walls such 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 manufacturing such a winding the first cable is inserted through the opening of the stator slot and pressed firmly into a cable slot arranged at the bottom of the stator slot and designed to retain the cable when it has been pressed in. A second cable is inserted through the opening of the stator slot and secured between this first cable and an opposing securing shoulder in the wall of the slot, after which a third cable is inserted through the opening in the stator slot and secured between the second cable and a securing shoulder in the slot wall opposite the second cable, and so on.
