1. A rotating electrical machine comprising:

  • a stator having ends, a stator body, and a stator winding inserted in the stator body;

    a rotor which rotates about an axis and is surrounded concentrically by the stator;

    wherein the stator winding comprises, in a concentric arrangement, a lower layer which is more remote from the axis, and an upper layer which is closer to the axis, of axially extending winding bars which emerge from the stator body at the ends of the stator, the winding bars being arranged, within an end winding, with their bar ends on two concentric circles in pairs one above the other in the radial direction; and

    wherein in winding bars of a pair which belong to different phases within a phase segregation, the bar ends are radial spread to increase the radial distance between the different phases.
