FIELD: electro-mechanical engineering. ^ SUBSTANCE: bandage of electric machine anchor winding is made in form of continuous solid coiling, coil to coil, in a layer of isolated wire of magnetic or non-magnetic material at whole axial length of bandage section of winding, which does not have other means of radial attachment. The bandage contains even number of wire layers with a lock of beginning and end of coiling on one of end sides. Below each single or double layer of wire, an insert ribbon is positioned which envelopes the anchor surface being bandaged in one layer and which is made of non electro-conductive reinforced material containing axially oriented direct threads rigid to stretching. Aforementioned insert ribbon is provided with collar stops on external surfaces along end edges. Collar stops are longitudinally reinforced with wire or non-metallic filaments rigid to stretching. Axial distance between their internal stopping surfaces is equal to axial size of surface being bandaged. ^ EFFECT: simplified construction, ensured maximal technically possible reduction of losses to vortex currents, ensured stable reliability. ^ 4 cl, 8 dwg |
