FIELD: electric engineering and electro-mechanical industry, namely, windings of electric machines.
SUBSTANCE: winding of electric machine, consisting of rigid coils, is made of rectangular cross-section wire and has groove and frontal parts. In accordance to the invention, each rod of winding during transition from groove part to frontal part and backwards is twice bent along the line passing at an angle of 45 degrees to longitudinal axis of wide side of rod, and frontal parts of coils of different phases of winding are positioned one after the other along the rotation axis of machine and bent along a circle.
EFFECT: ensured minimal possible overhang of frontal parts of winding coils due to their radial positioning, and also due to simplified manufacturing technology of coil and reduced fault probability of winding isolation due to the fact that rods are bent along their wide side.
